| Abstract: | This investigation evaluates the two different welding procedures, single-pass arc weld mode and multi-run arc weld mode, in both plates welding and cylindrical plate welding, by the method of thermal elastic-plastic finite element analysis. It is recognized that the latter is resultful in decreasing welding residual stress as well as welding residual strain. |

| Keywords: | welding residual stress residual strain temperature field numerical simulation |
