　　Resistance spot welding(RSW)represents about 90%of car body assemblies,due to its production convenience and cost effectiveness.For both aspects of safety and lightening vehicle structures,the introduction of the Ultra High-Strength Steels(UHSS)in the spot welded assemblies is increasing,and it brings to a new generation of multisheet multi-steel grades spot welded assemblies.
