Abstract

Resistance spot welding is a welding process where the assembly of work part is produced by electrode pressure and heat obtain from resistance with the flow of electric current. The shape and size of weld formed are depends on the shape and size of the electrodes. The strength of vehicle structure mostly depends on the weld structure. Thus, this project purposed to study the effect of different welding parameters to mechanical properties of spot weld. The parameter of resistance spot welding such as welding current, welding force, and welding time were changed follow by the parameters designated. In this project, the tensile strength and hardness test of lap joint in spot welding for 2.12 mm thickness of two layer welded sheet was investigated. The testing process that had been done is tensile shear-test by using Universal Testing Machine, hardness test by using Vickers Microhardness Testing machine, and surface microstructure by Scanning Electron Microscopy. By the results obtained in this project, parameter four seems to be the most excellence parameter compare from the others. The most less excellence is parameter one that has tensile and hardness value lowest. The results of this study found, parameter four suitable for spot welding process because it has high quality in terms of strength, hardness and microstructure.
