Abstract
The residual stresses and deformation, in terms of the thermoelastoplastic theory, were simulated with the finite element method using ANSYS 13.0 software for a 5A06 aluminum alloy plate after welding. The butt joint thickness of the plate was 6 mm. A 3D thermomechanical model of the plate was constructed. The dimensions and distribution of residual stresses in the welded structure should be analyzed after simulation. Appropriate welding technologies were chosen to control welding residual stresses and deformation. The efficient production of an aluminum alloy for the welded structures will be provided.
