Abstract

The invention provides an overall pressing device and method for stainless steel side wall laser lap joint stitch welding. The overall pressing device comprises a bottom plate and a corrugated plate pressing assembly, wherein the bottom plate is provided with a corrugated plate positioning assembly for positioning a corrugated plate, the bottom plate is provided with a window reinforcing beam pressing and positioning assembly for pressing and positioning a window reinforcing beam, a pressing air cylinder for pressing the corrugated plate is arranged on the corrugated plate pressing assembly, and the pressing assembly and the bottom plate are installed in a matched mode. The device has the beneficial effects that the gap between an external wall panel and the corrugated plate is reduced, and the welding quality is improved.

Description

technical field [0001] The invention belongs to the technical field of laser lap stitch welding of stainless steel side walls of rail cars, and in particular relates to an integral pressing device and method for laser lap stitch welding of stainless steel side walls. Background technique [0002] At present, domestic OEMs are committed to replacing resistance spot welding with laser welding lap welding process for the manufacture of stainless steel rail vehicles, so as to solve related problems such as traces of solder joints on the car body, poor air tightness, and low welding efficiency. Laser welding has been widely used in the manufacture of stainless steel rail cars due to its advantages such as stable joint welding quality, fast welding speed, and small welding deformation. However, due to the particularity of laser welding lap welding technology, high precision is required for the workpiece and assembly to ensure the welding quality of the joint. Therefore, high requi...
