摘要：
In this paper, welding residual stresses of welded H-beam considering both butt weld and fillet weld have been researched. Taking the welded H-beam frame as background, basing on technological parameters of arc welding, construction sequence and the fabricated method, the three dimensions thermal-mechanics finite element model of the welded H-beam has been established by the finite element analysis software. The distribution of welding residual stresses of welded H-beam considering both butt weld and fillet weld are simulated, and the simulation results are compared with the results that not considering butt weld. Numerical simulation results show that complicated stresses state appears in the junction between the butt weld and fillet weld, and the residual stress peak value increases.
