Abstract :
After the completion of pipeline girth welding joint, the joint may be strengthened or softened and have high residual stress. Most of weld indies are acceptable, but when pipeline work under inner pressure conditions and the weld joint is high-accident risk zone. This paper establishes indirect coupling pipe 3D pipe multilayer V girth weld based on a weld temperature field and stress field of finite element analysis program, and make temperature field simulation results compare with the experimental and simulation results from some references and analy those Comparison results, Analies those results of residual stress strength joint simulation in operation conditions (0MPa, 5MPa, 10MPa, 15MPa inner perssure) and summarizes their law of variation.
