Abstract

Numerical simulation welding process of box structure at different environment temperature, it obtains and tests deformation and stress distribution of ironing plate. The results show that deformation trend is convex on the bottom of U-shaped plate, and deformation is concave in the center of connecting plates on both sides. The maximum deformation position occurs the connecting plate extends from one end of the upper side. Deformation peak values at environmental temperature of 0oC, 20oC and 40oC are respectively 5.18mm, 3.481mm, 4.173mm. Error is respectively 10.5%, 8.5%, 8.1%. Stress peak values are respectively 460MPa, 452.1MPa, 431.7MPa. Error is respectively 11.8%, 9.8%, 6.9%. Welding stress and deformation results meet the requirement of engineering application. It proves accuracy of simulation results. When environment temperature is 0oC or 40oC, deformation is more than that of 20oC. Welding deformation and residual stress are larger at 0oC, so welding operation should be avoided in the low temperature environment.
