Resistence Spot Welding (RSW) is still the most used form of welding in the automotive industry,primarly for welding steel and also most favorable method for joining Dual-phase steel. One of the advanced steel used in the automotive
industry is dual phase steel,so it is important to properly select the welding parameters for these steel. Dual-Phase(DP800) are charecterized by a microstructure consisting of ferrite and martensite and offers favorable combination of high strength and good deformability.These properties have made them a potential candidate for the fabrication of automobile body frame
structures,which help increase fuel economy by down-gauging material thickness and improving the car worthiness of the vechile.The objective of this work is to conduct experimental and theoretical studies on resistance spot welded advanced
dual phase steel joint with copper interlayer.Here we evaluated the Mechanical properties and Metalluurgical charecterization of the base metal with different RSW parameters(Welding current,Time,Pressure) and it includes TSFL(Tenile Shear Facture Load),Hardness and Microstructural charecteristics of DP800 steel with copper interlayer.This experiment has evaluated by taking different value for the RSW parameters to a certain limit and we found out the area with higher hardness and lower hardness along the region of base metal and also the degree of softening in the HAZ(Heat Affected Zone) when the current increase.It is concluded that the major welding parameters was welding current
70(W),welding time(1sec),welding pressure(4.25bar) was founded by the experiment.
