DISSIMILAR STEEL COLD CRACK SUSCEPTIBILITY TEST METHOD

摘要

A dissimilar steel cold crack susceptibility test method with reference to the Weldability Testing Method of Y groove Cracking Test (GB4675.1 84) comprising test piece preparation test process and evaluation; a preferable welding rod is a welding rod matching with a metal material (1) or a metal material (2) or a welding rod with the grade thereof being between the metal material (1) and a metal material (2). The test can easily and reliably test and evaluate the dissimilar steel welding cold crack susceptibility. Furthermore the test method can provide a reliable basis for the selection of optimum welding material and preheating temperature during the welding of dissimilar steel.
