Abstract
This study presents how Numerical Simulation, by using the Finite Element Method (FEM), can help to avoid hot cracking phenomena for resistance spot welding of 6xxx AlMgSi alloys. It is well known that aluminum spot welding is a difficult task especially for 6xxx alloys. Small silicon contents in these alloys increase the cracking sensitivity dramatically in comparison with 5xxx alloys. In order to reduce tedious experimental work and to understand such problems SORPAS®, a commercial available Finite Element Method software for resistance welding, was used. Virtual simulation experiments for the innovative resistance spot welding process DELTA SPOT™ led to optimized welding parameters in order to get the desired nugget size without surface cracks.
