摘要：
This study made it clear that the following parameter"eqr" can determine the tensile shear strength of resistance spot welded joint. This parameter "eqr" represents the residual heat quantity of the contact part of the welded plates after welding time. It includes spot welding current, welding time, electrode force, electrode tip diameter and welded plate thickness. It was made it clear by experiments that the parameter"eqr" can be applied to estimate the tensile shear strength of uncoated steel and hot-dip coated steel that were the carbon steels strength class less than 490N/mm2.
