Description	Journal: Iop Conference Series: Materials Science and Engineering In this paper, we use TCL/TK integrated language analysis software and semi-ellipsoid heat source model and life-death element method to simulate the butt welding process of Q345 steel plate with thickness of 10 mm. We simulated and analyzed the temperature field, stress field and welding deformation of multi-layer welding. Through welding simulation analysis, we extracted the distribution of welding residual stress and welding deformation of butt joint, and obtained the transverse and longitudinal shrinkage of butt plate and the main reasons. The results show that the multi-layer butt welding seam and its adjacent area are under tension, and the numerical value generally reaches the yield strength, and the two sides are under compression. The tensile stress in the middle of the weld bead is the largest and decreases gradually toward both ends. The cross-sectional area of single-sided multi-layer welding seam is larger and asymmetric along the thickness of the plate. After welding, the transverse shrinkage and angular deformation of the welded parts are larger. At the same time, the accuracy of the simulation results is verified by actual welding and testing.
