Optimizing Stresses in Cold Metal Transfer Welded 316L Austenitic Stainless Steel

In the present study, the weld joints of Cold Metal Transfer (CMT) 316L ASS weld were investigated with three different heat inputs. The tensile strength of LHI welds (610 MPa) is the highest compared to MHI (603 MPa) and HHI (601 MPa) welds, which is due to the higher chromium and nickel content in the weld metal. The experimental findings were compared with the simulation outcomes using ANSYS R18.1. It was found that the total deformation of HHI welds was higher than that of MHI and LHI due to the content of alloying elements in the welds. The Von Misses stresses of LHI weld was found to be greater than MHI and HHI weld due to the input parameters during welding. The experimental results of yield strength are found to be lower than simulation which is helpful to predict the yielding criteria of ductile materials.
