DOTSLASER hand-held laser welding machine adopts the latest generation of fiber laser, which can realize the simultaneous output of multiple optical fibers. Compared with the traditional hard optical output system, it can increase the degree of freedom of processing, and can perform simultaneous processing of multiple beams and multiple stations Processing provides the conditions for more precise welding. It has the advantages of simple operation, beautiful welding seam, fast welding speed, and no consumables. Welding on thin stainless steel plates, iron plates, galvanized plates and other metal materials can perfectly replace traditional argon Arc welding, electric welding and other processes. The hand-held laser welding machine can be widely used in the complicated and irregular welding processes of cabinet kitchens, stair lifts, shelves, ovens, stainless steel door and window guardrails, power distribution boxes, stainless steel furniture and other industries.
