With the permission of the commission, welders may be admitted to inspections for several welding methods and types of work, provided that their training and work experience for each type of welding will meet the requirements of Art. 2 of these Rules.

16. For welders who have successfully passed the test of theoretical knowledge and practical skills, the administration of the enterprise (organization) issues certificates signed by the chairman and one of the members of the commission in the form according to appendix. one.

17. Welders who received an unsatisfactory grade in one of the types of testing (theoretical or practical) may be admitted to a new test after additional training, but not earlier than after 1 month.

18. Re-testing of knowledge should be carried out by permanent commissions:

a) periodically, at least once every 12 months *;

b) during a break in work in their specialty for more than 6 months;

c) before admission to work after the temporary suspension of the welder for violation of technology and poor quality of work.

* Welders who continuously work in their specialty and have proven themselves to be of high quality of work performed during the last year, confirmed by the results of control, by decision of the commission, can be exempted from repeated tests for a period of 1 year, but not more than 3 times in a row.

19. When conducting a re-inspection, by decision of a permanent commission for assessing practical knowledge, control welded joints made by welders in the manufacture of industrial products and structures for a period of not more than 3 months prior to the inspection may be allowed.

20. Additional tests of the welder's knowledge should be carried out:

a) when switching to new welding methods or types of work;

b) when welding products from new materials or when there is a significant change in the technology of welding, surfacing (introduction or exclusion of heating, use of new equipment or welding materials, etc.);

METHODS FOR DETERMINING THE MECHANICAL PROPERTIES OF METAL OF WELDED JOINTS (according to GOST 6996)

Methods for determining the mechanical properties of the welded joint as a whole and its individual sections, as well as the deposited metal for all types of welding of metals and their alloys, are regulated by GOST 6996;

The standard establishes methods for determining mechanical properties for the following types of tests:

a) testing the metal of various sections of the welded joint and the deposited metal for static (short-term) tension;

b) testing the metal of various sections of the welded joint and the deposited metal for impact bending (on notched specimens);

c) testing the metal of various sections of the welded joint for resistance to mechanical aging;

d) measuring the hardness of the metal of various sections of the welded joint and deposited metal;

e) testing the welded joint for static tension;

f) testing the welded joint for static bending (bending);

g) impact testing of the welded joint.

Tests carried out in determining the quality of products and welding consumables, the suitability of welding methods and modes, in establishing the qualifications of welders and the indicators of weldability of metals and alloys, must comply with the requirements of the standard. The choice of types of tests, types of samples and methods used is provided for in the standards and specifications for products.

Sampling

Test specimens are taken from samples cut directly from the controlled structure or from control joints specially welded for testing.

If the shape of the welded joint precludes the possibility of manufacturing samples of this type (parts of complex configuration, pipes, etc.), then samples can be taken from specially welded flat control joints.

When making control joints, the nature of the preparation for welding, the brand and thickness of the base metal, the grade of welding materials, the position of the seam in space, the initial temperature of the base metal, the welding and heat treatment conditions must fully comply with the conditions for manufacturing the controlled product or the special purpose of the test.

Welding of control joints intended for testing welding materials (electrodes, welding wires, filler rods, fluxes, etc.), if there are no special requirements, is carried out with cooling between the application of individual layers. The temperature to which the metal must cool is set by the standard or other technical documentation.

The dimensions of the plates for the manufacture of control joints are determined by the requirements indicated below.

For control joints performed by arc, electroslag and gas welding of flat elements, the width of each welded plate, unless otherwise specified in the standards or other technical documentation, must be at least:

50 mm - with metal thickness up to 4 mm;

70 mm - with a metal thickness of St. 4 to 10 mm;

100 mm - with a metal thickness of St. 10 to 20 mm;

150 mm - with a metal thickness of St. 20 to 50 mm;

200 mm - with a metal thickness of St. 50 to 100 mm;

250 mm - with a metal thickness of St. 100 mm.

The width of a control joint made of round or shaped steel must be at least two diameters or two element widths.

The length of the welded edges of the plates is determined by the size and number of samples to be manufactured, taking into account repeated tests, allowances for the width of the cut and subsequent processing, and with the addition of the length of unused sections of the seam. The dimensions of unused areas are taken equal to:

in manual arc welding with coated electrodes and gas welding - at least 20 mm at the beginning and at least 30 mm at the end of the weld;

in automatic and semi-automatic welding with any type of protection, except for flux, with a metal thickness of up to 10 mm - at least 15 mm at the beginning and at least 30 mm at the end of the weld, and with a metal thickness of more than 10 mm - at least 30 mm at the beginning and at least 50 mm at the end of the seam;

in automatic and semi-automatic submerged arc welding at a current of up to 1000 A in electroslag and arc welding with forced formation - at least 40 mm at the beginning and at least 70 mm at the end of the weld;

in automatic submerged arc welding at a current of more than 1000 A - at least 60 mm at the beginning of the seam.

The length of the unused section at the end of the seam for this case is taken equal to the length of the crater of the seam (the section having an incomplete section).

The dimensions of the plates for control joints performed by welding methods not indicated above are established by the relevant technical conditions.

In cases of plate welding with the use of attachment strips for the output of the beginning and end of the weld, it is possible to take samples along the entire length of the control joint. Attached strips are made from the same material as the plates.

The length of the attachment strips must be at least the size of the unused sections of the seam.

The dimensions of the samples cut from the controlled structure are determined by the number and dimensions of the samples.

During oxygen cutting of samples, their dimensions are determined taking into account the allowance for subsequent machining, which ensures the absence of metal that has undergone thermal influence during cutting in the working part of the samples.

It is recommended to cut blanks for samples from samples and control compounds on machine tools. It is allowed to cut blanks on scissors, dies, oxygen, plasma, anode-mechanical and other cutting methods.

An allowance for the size of the workpiece, which ensures the absence of a metal sample with properties changed as a result of cutting in the working part, is assigned depending on the cutting method. The minimum value of the allowance should be:

with a metal thickness of up to 10 mm: oxygen and plasma cutting - 3 mm, mechanical, including anode-mechanical cutting, - 2 mm;

with a metal thickness of more than 10 to 30 mm: oxygen cutting - 4 mm, plasma cutting - 5 mm, mechanical, including anode-mechanical cutting, - 3 mm;

with a metal thickness of more than 30 to 50 mm: oxygen cutting - 5 mm, plasma cutting - 7 mm, mechanical, including anode-mechanical, - 3 mm;

with a metal thickness of more than 50 mm: oxygen cutting - 6 mm, plasma cutting - 10 mm, mechanical, including anode-mechanical, - 3 mm.

When cutting blanks for samples from metal, in which properties in the working part of the sample do not change under the influence of cutting, it is allowed to reduce the allowances indicated above, but not more than two times.

The allowance for cutting methods not listed above must be specified in the regulatory and technical documentation for this type of product or for the sampling method.

In the manufacture of samples, it is necessary to take measures to exclude the possibility of changing the properties of the metal as a result of heating or work hardening that occurs during machining.

On samples, control joints and blanks from rolled sheets and pipes, the direction of rolling of the base metal in relation to the seam should be indicated.

Editing the control compound or a sample taken from the controlled structure is not allowed. It is allowed to edit finished samples outside their working part. When testing welded joints from pipes, the admissibility of straightening samples is stipulated by standards or other technical documentation.

If there are no other instructions in the standards or other technical documentation, then the deflection arrow f over a length of 200 mm (Fig. 1) should not exceed 10% of the thickness of the metal, but not more than 4 mm.

Sheet plane mismatch h in butt joints (Fig. 2) should not exceed 15% of the sheet thickness, but not more than 1 mm.

Heat treatment, if it is stipulated by the normative and technical documentation, is carried out before the finishing processing of the samples. Heat treatment may be applied to samples, control compounds or blanks for samples cut from them. In the case of normalization or hardening, heat treatment of specimen blanks is not allowed.

Heat treatment of control compounds or sample blanks is preferably combined with heat treatment of the controlled product. The procedure for conducting heat treatment in the manufacture of samples from materials with s in more than 1000 MPa (100 kgf / mm 2) is established by regulatory and technical documentation.

Stamping of samples, control joints of blanks and finished samples can be done in any way so that the stamp is located outside the working part of the sample and remains on it after testing.

Test conditions and evaluation of their results

Samples that have deviations from the drawing dimensions in terms of the cleanliness of processing, as well as mechanical damage in the working part, are not allowed for testing and are replaced by the same number of new samples made from the same sample or control compound. If the dimensions of the sample or control joint exclude the possibility of making new samples, a new sample is cut or a new control joint is welded.

If the results of mechanical tests comply with the requirements of standards or other technical documentation, in all cases, except for arbitration tests, it is allowed to use samples with a lower surface roughness class.

Unless otherwise specified in standards or other technical documentation, static tensile and static bending tests are carried out on at least two samples; tests for impact bending, for resistance to mechanical aging and impact rupture - at least on three samples; hardness measurement - at least at four points for each welded joint. If the dimensions of the welded joint exclude the possibility of placing four points, then it is allowed to reduce their number in accordance with the real possibilities.

The results for all types of tests are determined as the arithmetic mean of the results obtained from testing all samples. If there are no indications in the relevant standards or other technical documentation, then for all types of tests, except for tests for static bending and when measuring hardness, it is allowed to reduce the test results for one sample by 10% below the standard requirement if the arithmetic mean result meets the standard requirements. The permissible reduction in the results of testing samples for static bending and when measuring hardness should be specified in the relevant standards or other technical documentation. When testing for impact bending, the permissible decrease below the regulatory requirements is set to no more than 5 J / cm 2 (0.5 kgf × m / cm 2).

Tests of the welded joint for static bending and tension, as well as impact rupture and hardness measurements are carried out at normal temperature equal to 20 ± 10 °C. The temperature of the sample is taken equal to the temperature of the room in which the tests are carried out. Tests of metal of various sections of the welded joint and deposited metal for static (short-term) tension, impact bending (on notched specimens), as well as tests for resistance to mechanical aging are carried out at normal temperature or as required, specified in the relevant standards or other technical documentation, at high or low temperatures. When testing at a low or high temperature, the temperature of the sample is assumed to be equal to the temperature of the medium in which heating or cooling is carried out. In this case, it is allowed to determine the temperature on the witness samples.

The test results are considered unsatisfactory if they do not meet the requirements set forth above, or crystallization or cold cracks are found in the fracture of the sample, or on its surface (except when the presence of cracks is allowed by the relevant regulatory and technical documentation). If the results are unsatisfactory, the tests are repeated on twice the number of samples. If a sample whose test results are considered unsatisfactory has defects in the base metal or welded joint (except for cracks), it is excluded from the assessment and replaced with one new sample.

The overall test results are determined from the readings obtained from repeated tests. The results of the retests are final.

The methodology for determining the size of samples, the requirements for testing equipment, the conditions for testing and calculating the results must comply with: when testing for static tensile strength at room temperature - GOST 1497, at low temperatures - GOST 11150, at elevated temperatures - GOST 9651;

when testing for impact bending at low, room and elevated temperatures - according to GOST 9454;

when measuring hardness - according to GOST 2999, GOST 9013 and GOST 9012.

Other requirements for test conditions, sample sizing, test equipment and scoring should be specified in the standard or other technical documentation.

The protocol for all types of tests must contain: the designation of this standard, the thickness and grade of the base metal, the method of welding, the type of connection, the type of heat treatment (if it is performed), the sample index (by brand), the type of sample, the place of its selection, the results of this type testing of all samples, the presence of defects in the fracture of the sample, when testing welded joints - the place of destruction (for the weld metal, for the metal of the heat-affected zone, for the base metal).

According to the requirement specified in the regulatory and technical documentation, it is allowed to use samples of type VI (see Fig. 5) with an incision according to Fig. 7 or 8.

The symbol for impact strength or impact work includes: the symbol for impact strength (KS) or impact work (K); type of notch (concentrator) (U, V); test temperature (temperature +20 °С is not indicated); the maximum impact energy of the pendulum (the maximum energy of 300 J is not indicated); type of sample (type of samples VI and IX is not indicated); location of the notch (Ш - seam; ЗС - fusion zone; HAZ - heat-affected zone, t- distance from the fusion boundary to the notch axis). Meaning t specified in standards or other technical documentation. When the notch is located across the weld metal, fusion zone or heat affected zone, the letter P is placed at the end of the designation.

Testing the metal of various sections of the welded joint for resistance to mechanical aging

Resistance to mechanical aging is characterized by a change in the impact strength of the metal subjected to aging in comparison with its impact strength in the initial state. The resistance of a metal against mechanical aging is judged by the ratio of these values ​​expressed as a percentage or by the absolute (normative) value of impact strength after aging. Tests are carried out for the weld metal and various sections of the metal of the near-weld zone.

The blanks are subjected to artificial aging according to the method: tensile deformation based on obtaining (10 ± 0.5)% residual elongation within the estimated length l, limited by cores or risks. It is recommended to apply risks on the surface of the samples every 10 mm to check the uniformity of deformation along the length of the calculated part.

After elongation, the workpiece is subjected to uniform heating for 1 hour at a temperature of 250 °C (523 K), followed by cooling in air. From the working part of the blanks according to hell. fourteen; 15 or 17 take samples of type VI or IX, and according to hell. 16 - type VII or X. The axis of the notch must coincide with the axis of symmetry of the weld. The sampling scheme for the location of the notch in other areas of the welded joint is stipulated by the standards or other technical documentation.

The aging procedure provided for in this paragraph is applied to welded joints made of steels. The aging procedure for other metals and alloys, as well as a different heating temperature or deformation value for steel joints, are specified in standards or other technical documentation.

Measurement of metal hardness of various sections of the welded joint and deposited metal

Hardness measurement is carried out in the cross section of the welded joint in accordance with drawing. 18, 18a and 19.

Hardness is measured by Vickers (HV), Brinell (HB) and Rockwell - A, B and C scales (HRA, HRB and HRC), giving preference to Vickers measurement.

Vickers hardness measurement is carried out according to GOST 2999. The load on the indenter, depending on the strength of the metal of the welded joint sections and the width of the heat-affected zone, should be 98N (HV10) or 49N (HV50). If there are relevant instructions in the standards or other technical documentation, Vickers hardness is measured. The load on the indenter during such measurements can vary from 0.04 to 4.9N.

Brinell hardness measurement is carried out in accordance with GOST 9012, using a steel ball with a diameter of 2.5 or 5.0 mm.

The measurement of Rockwell hardness is carried out in accordance with GOST 9013 with a spherical-conical diamond indenter (scale A and C) or a ball steel tip with a diameter of 1.5875 mm.

Hardness is determined for joints obtained by fusion or pressure welding from steels of various grades and other metallic construction materials not less than 1.5 mm thick.

The hardness of the base metal, various sections of the heat-affected zone and the weld metal is measured along one or more lines indicated in Fig. 18. If the connection is made of metals of different grades, then the hardness is measured for each of them.

When measurements are performed in the immediate vicinity of the fusion boundary, it is recommended to carry out 2 - 3 measurements in accordance with position I of the line. 18a or additional measurements on the position II fig. 18a.

Note. Hardness measurement lines in all cases, except for position VII, pass through all sections of the welded joint: FROM- from 2 to 4 mm; C1- from 10 to 15 mm; but- thickness of the base metal, mm; H - fillet weld thickness, mm; q- preparatory section with a thickness of at least five layers; q 1 - section for measuring hardness with a thickness of at least six layers. For fillet welds with a concave or convex surface, the value FROM measured from the point of maximum concavity or convexity.

It is allowed to carry out measurements in the areas of the welded joint indicated in Fig. 19.

Vickers hardness measurement is carried out on microsections or samples with a polished surface, if the outline of the seam is visible without etching. The surface roughness of such samples should be from 0.40 to 0.63 µm. Measurement of Brinell or Rockwell hardness is carried out on macrosections or on samples with a ground surface, if the outline of the seam is visible without etching. The surface roughness of such samples should be from 1.25 to 2.00 µm. In the samples, the parallelism of the working and supporting surfaces must be observed.

Hardness of butt and corner joints made arc welding, measure: with a thickness of the base metal or fillet weld from 1.5 to 9 mm in accordance with position VIII of line. 18 along one dotted line; with a thickness of 9 to 25 mm - in accordance with positions I and III of drawing. 18 along two solid and one dotted lines; with a thickness of 26 to 60 mm - in accordance with position II or III of drawing. 18 along two solid and one dotted lines.

The scheme for measuring hardness with a base metal or fillet weld thickness of more than 60 mm is specified in standards or other technical documentation.

The hardness of welded joints obtained by electroslag welding is measured in accordance with position IV of the drawing. 18. The number of measurement points in the heat-affected zone must be at least 10.

The hardness of various parts of the weld metal is measured in accordance with the position V of the line. eighteen.

The hardness of welded joints obtained by pressure welding is measured in accordance with position VI, drawing. eighteen.

The hardness of the deposited metal during quality control of welding consumables is measured in accordance with position VII of the drawing. eighteen.

Static tensile test of a welded joint

When testing, the strength of the weakest section of the butt or lap joint or the strength of the weld metal in the butt joint is determined.

A. Determination of the strength of the weakest section of the butt and lap joint

When testing a welded joint for static tension, the tensile strength of the weakest section is determined. The calculation of temporary resistance is carried out according to GOST 1497.

2. The dimensions of the sample with a metal thickness of more than 50 mm are established by the relevant technical conditions.

The transverse axis of samples of types XXIV and XXV must coincide with the axis of the weld. For one-sided welds, the marking of the transverse axis of the sample is carried out along the narrow part of the weld (for electric arc welding) or along the burr (for contact or gas pressure welding). For double-sided welds, the marking of the transverse axis is carried out after grinding and etching the side surfaces of the sample along the macrosection or in the middle of the convexity of the weld welded from the second side.

The temporary resistance is determined by the formula:

where s in- temporary resistance, MPa (kgf / mm 2); k- correction factor; R - maximum force, N (kgf); F- cross-sectional area of ​​the sample in the smallest section before testing, mm 2 (m 2).

For carbon and low alloy structural steels, the coefficient k is taken equal to 0.9. For other metals, the value of the coefficient k established by the relevant technical documentation.

The weld bulge for Type XXIV specimens must be removed (see above).

Welded joint test for static bending

Tests are carried out for butt joints. The test determines the ability of the connection to take a given size and shape of the bend. This ability is characterized by the bending angle but(Fig. 36), in which the first crack is formed in the stretched zone of the sample, which develops during the test. If the length of cracks that occur during testing in the stretched zone of the sample does not exceed 20% of its width, but not more than 5 mm, then they are not a rejection feature. The place of formation of a crack or destruction is also determined (for the weld metal, the metal of the near-weld zone or the base metal).

Depending on the requirements established by the relevant regulatory and technical documentation, tests are carried out until the standardized bending angle or bending angle is reached, at which the first crack, which is a rejection indicator, is formed, until the sides of the sample are parallel or touch. The bending angle during the test before the formation of the first crack is measured in an unstressed state with an error of up to 2 °.

2. The total length of specimens of types XXVI, XXVII and XXVIII is taken equal to at least the specified value.

3. The cross-sectional shape of the specimen must be constant throughout its length.

The thickness of samples of types XXVI, XXVII and XXVIII with a base metal thickness of 50 mm shall be equal to the thickness of the base metal. With a metal thickness of more than 50 mm, the thickness of the sample is established by the regulatory and technical documentation. Samples of types XXVIa XXVIIa and XXVIIIa, the thickness of which is less than the thickness of the base metal, may be cut out in different sections of the cross section of the welded joint. Different regulatory requirements are established for the test results of samples of different types.

The convexity of the weld on both sides of the sample is removed mechanically to the level of the base metal with a roughness of up to 6.3 microns. In the process of removing the thickening, unless otherwise indicated in the regulatory and technical documentation, undercuts of the base metal are also removed. Plane thickening with samples of types XXVI and XXVIa should be along, and with samples of types XXVII, XXVIIa, XXVIII and XXVIIIa - across the seam. It is allowed to plan the thickening in any direction with the subsequent removal of the scratches. In addition to samples within their working part, they must be rounded with a radius of 0.1 of the sample thickness, but not more than 2 mm, by smoothing with a file along the edge.

Test specimens of types XXVI and XXVIa are carried out as indicated in Fig. 39, types XXVIIa and XXVIII - to hell, 40, type XXVIIIa - to hell. 40a. Distance between supports TO(Fig. 40) should be equal to: for samples of type XXVII - 2.5 D, for samples of type XXVIIa -D + 3a, for samples of type XXVIII - 3D. The distance for samples of types XXVI and XXVIa is indicated in Fig. 39, and type XXIIIa - to hell. 40a.

A prerequisite for testing is the smooth increase in the load on the sample. Tests are carried out at a speed of not more than 15 mm/min on testing machines or presses using support rollers.

Mandrel diameter D may vary depending on the steel grade, sheet thickness, heat treatment method and must be specified in the relevant regulatory and technical documentation. In the absence of special instructions, the diameter of the mandrel is assumed to be equal to two thicknesses of the base metal. Support corner radius r for samples of types XXVI, XXVIa, XXVII and XXVIIa choose according to the table. 15. For samples of type XXVIII r= 25 mm. For specimens of type XXVIIIa, the radius has not been established.

For one-sided butt welds, according to the requirement specified in the standards or other technical documentation, the widest surface or root section of the weld is located in the stretched zone. In the absence of special instructions, the surface of the seam should be located in the stretched zone.

If there are no other indications in the standards or other technical documentation, then for double-sided butt welds in the tension zone, for all types of samples, except for XXVIIIa, the second weld is placed. For samples of type XXVIIIa, the entire section of the weld falls into the stretched zone. When welding multilayer double-sided butt welds with a transverse overlap of passes, the side where the last pass was made is located in the stretched zone.

Connections with a backing seam are one-sided. Tests of butt joints of pipes for bending with a transverse (circular) location of the seam are carried out on samples with a thickening removed from the outside.

For a pipe diameter of £ 20 mm, specimens in the form of pipe segments are used.

With a pipe diameter of more than 20 to 45 mm, samples are used in the form of a pipe segment or flat (segment) samples.

With a pipe diameter of more than 45 mm, flat (segment) samples of types XXVII, XXVIIa and XXVIII are used, their dimensions are indicated in Table. 14. Samples are not straightened. Their shape in cross section is determined by the natural curvature of the pipe.

Testing of pipes with a diameter of 60 mm or less with transverse (circular) and longitudinal seams can be carried out on the samples shown in Fig. 42 or 43. The thickening of the seam on the outside of the pipe is mechanically removed to the level of the base metal.

Type XXIX

Type XXX

On samples cut from pipes made by butt welding, the flash must be removed from the outer and inner sides of the pipe to the level of the base metal.

The results of testing samples of types XXIX and XXX are determined by the value b(Fig. 44) when a crack appears on the sample surface. The nature of the crack must correspond to that indicated earlier.

If a crack does not form, the test is carried out until the sides come into contact.

The test is carried out by deformation of the sample under a press with a compressive load.

A prerequisite for the test is the smooth increase in force on the sample. The test speed shall be as specified above.

When testing samples with a circular seam, the latter is placed along the axis of application of the compressive load (Fig. 45), and when testing a sample with a longitudinal seam, the seam is placed in a diametrical plane perpendicular to the action of the compressive load (see Fig. 44).

If there is a longitudinal weld in the test specimen for the circumferential weld, it shall be located outside the tension zone.

Testing of connections of rods of circular or multifaceted section in the absence of regulatory and technical documentation and other requirements is carried out on the following samples:

with a diameter of the rod or a diameter of a circle inscribed in a polyhedral section £ 0 mm, segments of a natural joint with a removed thickening are tested;

with a diameter of a rod or an inscribed circle of more than 20 to 50 mm - pieces of a natural joint with a removed thickening or flat samples of type XXVIIa, the thickness of which is taken equal to half the diameter of a round rod or a circle inscribed in the section of a polyhedral rod;

with a diameter of the rod or a circle inscribed in the section of the polyhedron of more than 50 mm - flat samples of type XXVIIa, the thickness of the base metal of which is taken equal to half the diameter of the round rod or the circle inscribed in the section of the polyhedron.

In all cases, the working length of the sample must be ³ 250 mm, and the radius of curvature of the polyhedron faces is equal to 01 of the sample thickness, but not more than 2 mm.

Impact testing of a welded joint

The shock tensile strength test is carried out for welded butt joints of sheets up to 2 mm thick. .

The shape and dimensions of the sample must correspond to the drawing. 46. ​​When testing high-strength materials, it is allowed to change the design of the gripping part of the sample.

The test is carried out on pendulum impact testers with a device for fixing flat specimens. Specific shock work is determined by the formula:

where A y- impact work spent on sample rupture, J (kgf×m); V- the volume of the calculated part of the sample, equal to the product of the thickness of the base metal ( but) for the estimated length and width of the sample, cm 3 (m 3).
