EXPERIENCES WITH HAZ COLD CRACKING TESTS ON A C-MN STRUCTURAL STEEL

The heat-affected zone cold cracking tendency of a C-Mn structural steel was evaluated using controlled thermal severity (CTS) and Tekken Y-groove specimens. This permitted a comparison of the performance of the single-pass fillet weld test and the single-pass butt weld test and the development of improved understanding of the performance of the latter. No cracking occurred in the CTS tests, but severe weld or heat-affected zone cracking was encountered in the Y-groove tests under conditions which had been expected to be less likely to produce cracking than the conditions employed in the CTS tests. It was shown that special procedures are necessary in order to control the critical root opening in the Y-groove specimen. A preferred method is to employ a two-piece specimen which has wide root faces in the restraint portions. When these faces are in contact, the correct root opening is maintained in the test weld portion after welding the restraint portions.
