[0002] Compared to traditional welding technologies, laser welding boasts high welding efficiency and precision, and a wide range of applications. Because the laser beam can be focused on a very small area, resulting in a small heat-affected zone, laser welding has become increasingly popular in the precision welding of micro and small parts, and in many areas where large machinery or robots are unable to operate. Handheld laser welding devices are proliferating. However, the handheld laser welding devices currently available on the market lack laser switch light monitoring and control capabilities, requiring multiple or multiple people to operate the device in coordination. These devices have poor integration and automation, resulting in low work efficiency. If the workspace is large and the equipment is far away, false triggering is likely to occur, posing a significant risk to personnel safety, equipment safety, and environmental safety.
