Effect of Electrode Materials on Nugget Deflection in Spot Welding of Non-equal Thickness Stainless Steel
Taking stainless steel resistance spot welding as an example, the influence of Cr-Zr-Cu electrode, Be-Cu electrode, W-Cu electrode on nugget offset of non-equal thickness plate resistance spot welding was analyzed. By making electrodes with the same shape, Cr-Zr-Cu electrode was used on the side of thick plate, and Cr-Zr-Cu, Be-Cu, W-Cu electrode was used on the side of thin plate. Under the premise of consistent welding parameters, nugget size and thickness and morphology was analyzed. The analysis results show that the phenomenon of nugget shift is obviously improved by using Cr-Zr-Cu electrode on the thick plate side and W-Cu electrode on the thin plate side.
