Abstract

The invention provides a block side wall installing and welding tool and process for a laser welding structure. The block side wall installing and welding process comprises the following steps that S1, an installing and welding frame and an aluminum plate profiling working tread are adopted as a tool main body; S2, an exhaust groove and a sealing groove are milled in the aluminum plate profiling working tread, and a vacuum pump is used for adsorbing a wallboard to the working tread through the sealing groove; S3, a corrugated plate is pre-spotted on the wallboard through a single-face pre-spotted technology, and the corrugated plate is positioned through profiling pressing positioning; S4, a layer of insulating paint is sprayed on the surface of the tool to prevent the wallboard and the tool from generating electric sparks to burn a strong board during pre-spotting; and S5, a gantry is assembled on the tool, and pressing and spot fixation of a framework and the wallboard on the tire position is achieved through the gantry. According to the block side wall installing and welding tool and the process for the laser welding structure, the wallboard is installed on a carbon steel installing and welding foundation platform in an adsorption mode, and laser automatic welding can be achieved under the condition that the tool is not pressed or positioned; compared with the spot welding,and after automatic laser welding is achieved, the quality of the exposed face is obviously improved.

Description

Technical field [0001] The invention belongs to the field of rail vehicles, and in particular relates to a welding tooling and process for the segmented side wall of a laser welding structure. Background technique [0002] In the field of rail vehicles, stainless steel car bodies are more and more popular in various cities; at present, the welding of stainless steel car bodies mostly uses molten gas arc welding (MAG) and tungsten arc welding (TIG). MAG welding can conveniently perform welding in various positions. It has the advantages of faster welding speed (generally 300-500mm / min) and high deposition rate. However, due to the need for wire addition, manual welding, and unstable heat input, It is easy to produce welding slag, spatter, crater pores and surface crack welding defects, and the heat-affected zone is large. TIG welding adopts pulsed arc, with low heat input and uniform heat input at all points of the weld, it better realizes the control of heat input; the weld is d...
