Jun 01,2018&0183;Filler metal addition has been investigated as an effective way to enhance mechanical properties of cold rolled mild steel in resistance spot welding.In the present study,filler metal from 30 to 80 mg was added to the spot weld to study its effect on mechanical behaviour of spot weldments.The effects of expulsion on microstructure and tensile shear strength of spot welds have been investigated for a high-strength cold rolled sheet steel.Spot welds with expulsion are characteristic for a “double im-age” near the fusion line,an equiaxed dendritic grain zone along the faying surface,and deep indenta-tions on the outer surfaces.
