3.2 Tensile shear strength of resistance spot welding
of Al/steel with consideration of results from dissimilar welding between aluminum/steel sheets using one step weld schedule, two step weld schedule (post weld) was carried out with post weld current and various post weld time. Figure 5(a) shows that the peak load being measured with tensile shear strength test is not influenced by post weld current, which should provide more heat input on interface for IMC growth.
