The weldability of materials is still for many years a highly contentious issue, particularly regarding the causes of the hot crack formation. Because of the process-related temperature and emissions, direct measurement for the arising strain in the close vicinity of the welding process is challenged. Therefore, the externally loaded hot cracking tests remain for decades the only way to determine...
Finite element analysis (FEA) model of the solidification process in the cast pin tear test (CPTT) was developed using the commercial software ProCAST™. Modeling predictions of the solidification and strain accumulation sequences and of the cracking sensitive region location were validated using parallel CPTT testing of Alloy 52M filler metal. Predicted pin length dependences of the hot tearing indicator...
