Abstract

The embodiment of the invention provides a laser welding technology. A laser device and a welding head are adopted for welding. The welding head is provided with a double-beam lens used for splitting a single beam into double beams. The method comprises the steps that beam split mass parameters generated after an output laser of the laser device passes through the welding head are measured; the target welding position is determined according to the beam split mass parameters; a welding material is fixed at the target welding position; and the laser device is started to weld the welding material. In the embodiment, the double-beam lens is arranged in the welding head, the double-beam laser is formed after the laser passes through the welding head, the welding material is welded through the double-beam laser at the target welding position, a welding line of the welding material is in a U shape, and the requirement of the electromagnetic valve welding technology is met.

Description

technical field [0001] The present application relates to the technical field of laser welding, in particular to a laser welding process, a laser welding device and a laser welding equipment. Background technique [0002] With the development of metal welding, the current mature welding methods include: resistance welding, argon arc welding, electron beam welding, plasma arc welding, laser welding, etc. [0003] Laser welding is also divided into a variety of laser light sources, including CO2 laser welding, YAG laser welding, and fiber laser welding. Welding is mostly used in the automotive industry and the electronics industry. Many electronic devices are welded by fiber laser, and the welding process is also diverse. [0004] Welding is an important process in the production of metal full-sealed devices (such as solenoid valves, air pressure valves), and is used to achieve firm and permanent connections of metal parts of solenoid valves. As a precise, efficient and high...
