Investigation of Welding Parameter on Resistance Spot Welding of Stainless Steel and Mild Steel Sheet

This final report or dissertation of Final Year Project outlines the background of the project “Investigation on the Effects of Welding Parameter on Resistance Spot Welding of Stainless Steel and Mild Steel Sheet”. The resistance spot weld of metals such as mild steel generally more challenging than that of another metals due to difference in the physical, chemical and mechanical properties of the base metals. This Final Year Project aims to investigate the effect of weld current, weld time, and electrode force/pressure on resistance spot welding of stainless steel and mild steel sheet. Spot welding is the most economical way to join two pieces of sheet metal. While joining sheet metal is the most common use for the process, resistance welding (RW) equipment actually can be used for a large variety of joining and heat-treating projects, some of which are not so well-known. The research methodology on this project has been studied and identified. The experimental process that had been done throughout this semester is tensile test, microstructure inspection, and micro hardness test.
