Zerstörende Prüfung von Schweißverbindungen an metallischen Werkstoffen - Heißrissprüfungen für Schweißungen - Lichtbogenschweißprozesse - Teil 2: Selbstbeanspruchende Prüfungen (ISO 17641-2:2015); Deutsche Fassung EN ISO 17641-2:2015
Overview
This part of ISO 17641 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. This part of ISO 17641 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. This part of ISO 17641 describes only how to carry out the tests and report the results. It does not give any acceptance criteria. The responsible German standardization committee is Joint Working Committee NA 092-00-05 GA "Gemeinschaftsarbeitsausschuss NAS/NMP: Zerstörende Prüfung von Schweißverbindungen (DVS AG Q 4/Q 4.1)" ("Joint Working Committee NAS/NMP: Destructive testing of welds (DVS AG Q 4/Q 4.1)") at Standards Committee Welding and allied processes (NAS) at DIN.
