Using finite element analysis to simulate all process of welding in the present paper studies the residual stress of welded steel plates.Actually measuring the residual stress of weld steel plates is by method of hole-drilling,and proves feasibility of finite element analysis.Further we research and analyze the influence of residual stress on the propagating of fatigue crack. Research divides into three directions : 1.Using finite element analysis to simulate 2-D welded plate,and study the residual stress of welded plates.Further we research the residual stress on different welding way(Shield Metal Arc Welding and Submerged Arc Welding),different weldind condition(the constrained boundary and change of welding speed etc). 2.Actually measuring the residual stress on the steel plates of Shield Metal Arc Welding and Submerged Arc Welding. 3.Using the steel plates of Submerged Arc Welding studies fatingue- tension-life experiment and analyzes the influence of residual stress on the propagating of fatigue crack.
