Influence of Addition the Al Power on the Tensile Shear Loads in Resistance Spot Welding of TC4/AZ31B

Abstract:

The tensile shear loads in resistance spot welding of TC4/AZ31B with addition Al power have been investigated in this paper. The results showed that the tensile shear loads with and without addition Al power were 2.636 KN and 3.692 KN when welding current was 9800A , respectivly. And the values changed 2.971 KN and 4.167 KN when the welding current was 11300A, respectively. Morphology characteristics of the welding zone were studied by scanning electron microscopy (SEM), energy dispersive spectrometer (ESD). The results suggested that the addition of Al power on the sheets of TC4 and AZ31B increased much in the tensile-shear loads when welding TC4 and AZ31B by RSW.
