Study of Contact Behavior in the Pre-squeeze Stage of Aluminum Alloy Resistance Spot Welding
In this paper, an axis-symmetric contact finite element analysis (FEA) model of resistance spot welding (RSW) for aluminum alloys was developed using ANSYS. It provided effective analysis of contact behavior in the pre-squeeze stage of aluminum alloys RSW. The computational simulation interpreted the reason leading to contact pressure distribution shape and contact area size at the faying interface between work-pieces. And the factors and rules affecting contact behavior were also discussed in this paper.
