摘要：
Thermo-mechanical simulations of single butt welding were performed for CLAM steel, utilizing commercial software, ANSYS, in which double ellipsoid heat source model was introduced and phase transition action was precluded. The residual stress distributions based on the calculated temperature field were calculated and almost coincided with those from the experimental results. Based on the simulation, it was also found that tensile stress exists in the partial melting region and bond area; whilst compressive stress turns on away from weld zone. The residual stress over the cross section is very little and it is also confirmed to be tensile stress. ©2010 Editorial Board of CHINA WELDING.
