Evaluation of solidification cracking of Ni-based alloy dissimilar welds based on Trans-Varestraint test

This study aims to evaluate the weldability of dissimilar welds with Inconel 625 and Hastelloy C-276 nickel-based alloys deposited on ASTM A36 AISI 1045 carbon steel plates. The were carried out by GMAW process evaluated Trans-Varestraint test. test results statistically evaluated, Fusion Zone solidification processes simulated in JMatPro software using several dilution levels. analysis variance (ANOVA) showed that two different base metals did not affect 625. However, alloy a significant drop compared A36. as filler metal greater susceptibility cracking than all other pairs tested, according Moreover, ANOVA indicated heat input levels influence sets’ weldability; this was probably because there only tiny variation simulation indicates higher promote precipitation larger secondary phase fraction.
