62 Characteristic parameter of dynamic resistance for splash in resistance spot welding low carbon steel to some extent is reflected by the sudden change of DRC and its change ratio.
63 Test results showed this method is credible, and it can be used to inspect the spot weld quality of car bodies quickly by 100%, and inspect the spot welding quality of any sheet metal.
64 An axisymmetric finite element electro - thermo - mechanical model for resistance spot welding process is introduced.
65 Expulsion is highly undesirable during the resistance spot welding for it decreases the weld quality.
