Handheld laser welding machine is a new‑type portable welding device. Using high‑energy laser as heat source, it realizes precise and efficient metal fusion via handheld welding gun. It features flexible operation, fast welding speed and narrow heat‑affected zone with minimal workpiece deformation. Weld seams are smooth and nice, requiring little or no post‑grinding work. With low learning threshold, ordinary workers can master operation after short‑term training. Widely applied for cabinet & kitchenware, stair & elevator, door‑window guardrail, auto parts, for welding stainless steel, carbon steel and aluminum alloy.
