TL;DR: In this article, a comprehensive structural-thermoelectric model for single-sided spot welding (SSSW) is presented. But the model is limited to the case of closed tubular parts.
Abstract: As a new kind of lightweight structure, hydroformed tubes are now widely used in vehicle bodies. The single sided spot welding (SSSW) is a variation of resistance welding used in joining hydroformed closed tubular parts and vehicle structures. During the process of SSSW, large deformation and complex contact status of the workpieces occur because there is no inside support. The time variation of the contact region and pressure distribution changes the flow paths for electric current timely and brings a fierce shunting at the position far away from the axis line, which prevents the heat concentration at the faying surface of workpieces. The characteristics of SSSW different from those of classical resistance welding mentioned above make it difficult to determine rational welding processing parameters for SSSW. In the present paper, a comprehensive structural–thermoelectric model is established. Using the incrementally coupled analysis of finite element analysis, the electrical, thermal and mechanic...

TL;DR: In this paper, a finite-element analysis of two-dimensional thermal stresses and metal movement during bead-on-plate and butt welding in 6061-T6 aluminum alloy is presented.
Abstract: This is the second part of a study of thermal stresses and metal movement during welding. Part I described the finite-element analysis of two-dimensional thermal stresses and metal movement during bead-on-plate and butt welding. Part II presents results of experiments on bead-on-plate and butt welds in 6061-T6 aluminum alloy. Measurements were made of changes of temperature, thermal strains, and metal movement during welding. The paper then compares experimental data with analytical results. Good agreements were obtained between experimental and analytical results.

TL;DR: In this paper, a novel approach to estimate the local weld toe radius is presented, and the derived values are utilized to calculate the respective stress concentration at various locations of the weld using state-of-the-art notch-factor approximation equations.
