Abstract
The invention discloses a method for welding multilayer thin metal sheets and a thick metal sheet. The method comprises the following steps that the multilayer thin metal sheets are clamped through a clamp, and the ends of the multilayer thin metal sheets are welded by using metal inertia gas welding; the welded ends of the multilayer thin metal sheets are in butt joint with one end of the thick metal sheet, and then welding is carried out. According to the method for welding the multilayer thin metal sheets and the thick metal sheet, welding efficiency and welding quality between the multilayer thin metal sheets and the thick metal sheet can be remarkably improved.
Description
technical field [0001] The invention belongs to the field of metal welding, in particular, the invention relates to a welding method of multi-layer thin metal plates and thick metal plates. Background technique [0002] At present, the methods for welding thin metal sheets (for example, aluminum and aluminum alloy sheets) mainly include laser welding, brazing, argon tungsten arc welding, and partial solidification welding. Among them, brazing is usually used for the welding of multi-layer metal sheets, but brazing often cannot meet the requirements of welded products due to its low strength. For the welding of metal sheets with high weld strength requirements, argon tungsten arc welding is usually used. Although argon tungsten arc welding can meet the requirements of welding strength, its welding efficiency is relatively low. In addition, although the other welding methods can achieve a small adjustment range of parameters, and can well control the formation and temperature...
