DISSIMILAR STEEL REHEAT CRACK SUSCEPTIBILITY TEST METHOD

摘要

A dissimilar steel reheat 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 reheat crack susceptibility. Furthermore, the test method can provide a reliable basis for the selection of optimum welding material and heat treatment temperature during the welding of dissimilar steel.
