ISO 17641-2:2015 specifies the required specimens, the test piece dimensions, and the procedures to be followed to carry out self-restraint hot cracking tests.The following tests are described:- T-joint weld cracking test;- weld metal tensile test;- longitudinal bend test.The tests are designed to provide information about the hot cracking sensitivity of weld metals. The tests are not suitable for the assessment of parent materials.ISO 17641-2:2015 applies primarily to fully austenitic stainless steels, nickel, nickel base, and nickel copper weld metals. This part of ISO 17641 can also be used for other weld metals.ISO 17641-2:2015 describes only how to carry out the tests and report the results. It does not give any acceptance criteria.
