The invention relates to an air blowing module for laser flight welding. The air blowing module comprises a flat blowing nozzle, wherein the flat blowing nozzle is of a whistle-shaped structure; an air outlet and a plurality of air inlets are respectively arranged at two ends along the length direction of the flat blowing nozzle; the air outlet extends along the width direction of the flat blowingnozzle; a plurality of side-by-side small pores of the same pore diameter serve as the air inlets; and the air inlets are uniformly distributed along the width direction of the flat blowing nozzle. The invention further provides a welding system for laser flight welding. The air blowing module is simple in structure; through the convection design of the air inlets and the air outlet, the air inlets are all adopted for controlling the convection of airflow which passes through the flat blowing nozzle, so that the air outflow uniformity of the air blowing module can be guaranteed; and accordingly, plasma negative pressure can be formed on the surface of a weld, zinc vapor can be blown away, and the problem that pores are formed during the laser flight welding of a galvanized plate can be effectively solved.
Description
technical field [0001] The invention belongs to the technical field of laser welding, and in particular relates to an air blowing module and a welding system for laser flying welding. Background technique [0002] The manufacturing of the automobile industry has entered an automatic, efficient and high-quality stage. Compared with ordinary welding processes, laser welding has significant advantages such as concentrated heat source energy, fast welding speed, small thermal deformation, and less spatter. Half of the auto parts in Europe and the United States Or the entire vehicle manufacturing process uses laser welding; in high-power laser welding, flying laser welding is favored for its solution to the connection of high-density welds. And it is more and more widely used in the welding manufacturing of automobiles. Compared with spot welding, it can significantly improve the welding cycle. [0003] In order to increase the corrosion resistance of the car body panels, galvan...
