  • Abstract:
  • Arc welding is an important joining process widely used in many industrial applications including production of automobile, ships structures and industrial parts. In welding process, the moving electrode causes highly non-uniform temperature distribution that leads to residual stresses and distortions in thin plates. To control the distortions and increase the quality of welded plates, a clamp can be used as a practical and low cost method with high efficiency. In this study the finite element analysis of residual stresses in shielded metal arc welding of two similar plates is performed with the ANSYS software. This analysis includes a finite element model for the thermal and mechanical welding simulation.
