The design principle of the utility model is as follows: because the heat conductivity coefficient and the linear expansion coefficient of the magnesium alloy are larger, the size of the magnesium alloy template is larger and the number of welding seams is larger. During welding, the welding seam is positioned at the edge of a molten pool, and the metal of the molten pool is heated and expanded, so that the welding seam and the adjacent area are extruded to present compressive stress, and the area far away from the welding seam is tensile stress; when the arc is far away, the weld metal cools and contracts, so that the area near the weld is tensile stress, and conversely, compressive stress is presented away from the weld area. The rapid heating and rapid cooling occur in the welding process, particularly severe temperature gradient is generated near the welding seam, large residual stress occurs on the component, deformation is caused after the welding of the template, and deformation of 4-6mm usually occurs after the welding of the template; after the welding deformation of the template, the form of the template is presented as concave deformation of the middle part of the side rib and asymmetric deformation of the two ends of the handle and the panel. Although the periphery of the panel is greatly deformed, the panel is far away from the welding seam area, and is mainly elastically deformed in the welding process, so that the template can be restored to the initial state after a certain acting force is applied.
