Abstract

This Final Year Project outlines the background of the project “The Effect of Different Thickness Material Stacking for Four Layer Spot Welding”. Spot welding is one of the metal joining processes that mainly use in the automotive industries. Resistance spot welding of four layer metal sheet generally more challenging than three layers of spot welded sheet due to the several interfaces. The strength of vehicle structure mostly depends on the weld structure. Thus this report intended to research the mechanical properties of four layer welded sheets from different thickness. The research methodology on this project has been studied and identified. The experimental process that had been done is tensile test by using INSTRON Universal Testing Machine. In this research, the strength on the tensile shear-test of lap joint in spot welding of 2.80mm, 3.50mm and 4.40mm thickness of four layer welded sheet was investigated. All the results were then compared with three layer of welded sheet with thickness 2.80mm. Three layer of 2.80mm thickness welded sheet function as a benchmark in this study. From the discussion, it was discovered that four layer of spot welded sheet have higher tensile strength compared to three layer of welded sheet. The study is hopefully will help automobile manufacturer in producing a better product for the automobile industry.
