| Abstract: | By means of welding experiment and thermal elastic-plastic simulation of butt structure and fillet structure,the principles of welding temperature and residual deformation for measuring points were studied.The results showed that the measuring points went through "heating-peak temperature-cooling".The fillet deformation of butt structure was smaller,its transverse shrinking deformation was bigger;the fillet deformation of fillet structure was bigger,its transverse shrinking deformation was smaller. |
