Characterization Of Galvanized And Copper Sheets Joined By Resistance Spot Welding

Abstract

Due to the metal's propensity to develop oxides during welding, joining conductivity metals like copper and galvanized iron (G.I) using conventional welding processes is a time-consuming and costly endeavor. Welding these metals may be expensive, however resistance spot welding (RSW) and other technologies have shown to be a cost-effective option in a number of situations. Resistance spot welding is a common technique in the fabrication of sheet metal for the aerospace and automotive industries.Copper and Galvanized Iron sheets were welded at an angle, and the welding pressure was adjusted during the RSW process to create a strong yet visually distinct connection between the two metals. In contrast, duration and current for welding were held constant in the experiment. To do this, you'll need copper 1.5 mm thick & G.I0.8 mm thick. When the welding is done, XRD and SEM will be used to examine the welded area's microstructure in order to learn more about its characteristics. The results of this experiment demonstrated that the RSW method was effective for welding Copper and Galvanized Iron covered with magnesium sheets, among others.
