Bimetallic combinations of Monel 400 and Hastelloy C276 are widely used in the high temperature applications. This paper investigates the weldability of these metals by Gas Tungsten Arc Welding technique employing ERNiCrMo-3 filler wire. Studies were carried out to characterize the weldments for its mechanical and metallurgical properties. Tensile tests confirmed that the strength of the weld zone is higher as compared to the parent metals. Structure-property relationships have been studied using the combined techniques of optical microscopy and SEM/EDAX analysis.
