MCWlaser 2 In 1 Head 1000W 1500W 2000W Handled Fiber Laser Welding Machine with Weld Seam Cleaning FunctionAdvantages We've upgraded our welding process by replacing the fixed optical path with a handheld welding gun, which is ideal for laser welding long distance and large workpieces. This new method results in a smaller heat affected area, preventing deformation, blackening, or traces on the back of the workpiece. Additionally, it allows for deeper welding and produces a firm and sufficiently melted material without any depressions on the convex parts of
