Abstract
Resistance spot welding is a fast, easily automated and easily maintained process with high productivity. These advantages result in the highly usage of resistance spot welding in automotive industrial. Almost 90% of the assembly of automotive parts are using this joining process. This project was performed to investigate the design parameters of sheet metal welded joint based on transient thermal condition. Also, the transient thermal condition of the sheet metal is analysed and the factor of safety is proposed at the end of the project. The design parameters included are number of spot welding, dimension, material and thickness of sheet metal. Steady state and transient thermal analysis were conducted on aluminium alloy 5182 sheet metal with dimension 120mm×60mm, thickness 1mm to 6mm and number of spot weld two to five. Suitable combination of thickness of sheet metal with number of spot weld is proposed after the simulation and analysis. The CAD model and analysis of sheet metal was performed by using ANSYS software. The results of both the thermal analysis were heat flux, reaction probe and factor of safety. Scoring is done to determine the number of spot weld for each thickness of the sheet metal. It is found that two number of spot weld is suitable for thickness of 1mm, 2mm, 4mm, and 6mm for the dimension mentioned above. As for sheet metal with thickness 3mm and 5mm, five and two spot weld is suitable respectively.
