Abstract

This paper investigates the influence of spot-welding process on surface accuracy of cold and hot stamping assembly part. In order to control surface accuracy after spot welding, simulative work was carried out. In simulative work, welding sequence under given clamping position was considered. The results show that under the same clamping positions, the welding sequence has an impact on welding deformation. Welding residual stress derived from continuous spot welding is considered the main reason that contributes to welding deformation. For assembly part which possesses multiple welding spots, enough time gap between welding spots can be helpful for welding residual stress release. Additionally, more clamping positions also favour reducing welding deformation. By using relevant welding process for specific welding assembly, surface accuracy of the assembly part can be well controlled within ± 0.5mm. Spot welding simulation plays a crucial role for welding surface accuracy control of assembly part, thereby reducing the number of trial and error attempts.
