1. Laser metal welding, the basic welding seam is beautiful and fast, the operation is easy to learn, the welding is firm, and the sealing is good; 2. The portable air-cooled handheld laser welding machine adopts an integrated integrated fiber laser and is equipped with a self-developed wobble welding head. The high-tech air-cooled heat dissipation system fills the new application of hand-held welding in the laser equipment industry. It has multiple advantages such as simple operation, beautiful weld seam, fast welding speed, small size and convenient transportation. It is suitable for welding thin stainless steel plates, iron plates, and galvanized plates. , aluminum alloy and other metal materials, it can perfectly replace traditional argon arc welding, electric welding and other processes. It can be widely used in complex and irregular welding processes in cabinets, kitchens and bathrooms, stair elevators, shelves, ovens, stainless steel door and window guardrails, distribution boxes, and stainless steel home furnishing.
