But this kind of spot welding also has obvious disadvantages. For example, the weld size of spot welding is large, and it is not easy to control the penetration depth of the weld.
Therefore, spot welding is not suitable for products that require sealing and cannot be penetrated

Abstract

The invention discloses a laser welding system and method for a metal plate. The method comprises the following steps that a welding track of a to-be-welded metal plate can be obtained through a welding control unit; then the to-be-welded metal plate is fixed below a light emitting surface of a laser galvanometer by a control clamp based on the welding track; the target welding distance between the laser galvanometer and the metal plate is obtained, the actual distance between the laser galvanometer and the metal plate is adjusted to be the target welding distance; a laser generator is controlled to emit laser according to a preset laser parameter; and the laser is controlled by the laser galvanometer to move according to the welding track. According to the laser welding system and method,the laser is a nanosecond-level laser, high-frequency and high-speed welding of the metal plate can be realized, and high-frequency and high-speed welding can effectively reduce the weld joint size of the metal plate and improve the accurate control of the penetration depth.

Description

technical field [0001] The present application relates to the technical field of laser welding, in particular to a laser welding system and method for metal plates. Background technique [0002] Laser welding has the advantages of high precision, fast speed, and easy automation, and is very suitable for welding thin metal plates. [0003] In the existing metal thin plate laser welding technology, most of the metal thin plates are spot welded to form a connection joint with a certain tensile strength. But this kind of spot welding also has obvious disadvantages. For example, the weld size of spot welding is relatively large, and it is not easy to control the penetration depth of the weld. Therefore, spot welding is not suitable for products that require sealing and cannot penetrate through. Contents of the invention [0004] Embodiments of the present application provide a laser welding system and method for a metal plate, which are beneficial to reducing the size of the ...
