scope:

This part of ISO 17641 specifies the required specimens, thetest piece dimensions, and the procedures to be followed to carryout self-restraint hot cracking tests. The following tests aredescribed: ? T-joint weld cracking test; ? weld metal tensile test;? longitudinal bend test. The tests are designed to provideinformation about the hot cracking sensitivity of weld metals. Thetests are not suitable for the assessment of parent materials. Thispart of ISO 17641 applies primarily to fully austenitic stainlesssteels, nickel, nickel base, and nickel copper weld metals. Thispart of ISO 17641 can also be used for other weld metals. This partof ISO 17641 describes only how to carry out the tests and reportthe results. It does not give any acceptance criteria.
