Abstract

The simulation of heat flow, residual stress, and thermal distortion developed in A36 steel plate using a known volume of Zn50 brazing alloy for torch brazing technique is presented in this paper. FEHT software and GTstrudle codes were used for the heat transfer and residual stress simulation, respectively. The result of the heat flow simulation showed excessive cooling at the joints corner following convective heat loss to the ambient and maximum heat flux gradient thereby making the joint predisposed to underfill. Also the von misses stress and strain distribution in the plate showed that the residual stress is compressive and is limiting at 1800 N/mm2, localized in the joint. This is a basic understanding for impedance to thermally induced cracking.
