Abstract

The dissimilar metal joints of have been emerged as a structural material for various industrial applications which provides good combination of mechanical properties like strength, corrosion resistance with lower cost. The quality of weld in MIG mainly influenced by independent variables such as welding current, speed of electrode and Torch angle. The planned experiments were conducted in the MIG welding machine. Image J software was used to find out the depth of penetration depending upon the temperature variation. Thermal flux and Thermal gradient values were obtained moderate value on that specimen analyzing through FEA. The good weldment obtained in the input parameter was AMPS 160 VOLT-18 Torch angle 45º for 6 mm thickness plate. It does not create any major changes and failures in the tensile and Hardness testing process and it was comparatively good and moderate depth of penetration value compared than others. According to the Taguchi design the optimized tensile strength parameter value for the 6 mm plate on EN 8 & SS409 steel was AMPS 140, VOLT-22, and Torch angle 45 º.
