| Abstract: | Welding residual stresses and distortions have been puzzling difficult problems in ship industries for a long time.This paper presents the basic numerical theories for forecasting welding residual stresses and distortions,A real-time 3D numerical simulation has been executed to the welding process of a welding T-joint by using MSC.Marc FE analysis software,and computed results such as welding temperature field,residual stress distributing and angular distortion are drew out and discussed. |
