Laser welding is to use high-energy laser pulse to locally heat the material in a small area, and the energy radiated by the laser is diffused through the internal heat conduction of the material to melt the material to form a specific molten pool. It is a new type of welding method mainly aimed at the welding of thin-walled materials and precision parts, which can achieve spot welding, butt welding, overlap welding, sealing welding, etc. It has a high aspect ratio, small weld width, small heat affected zone, small deformation, fast welding speed, smooth and beautiful weld seam, no need for treatment or simple treatment after welding, high weld quality, no pores, precise control, small focus light point, high positioning accuracy, and easy to achieve automation.
Weldable shapes include points, lines, circles, squares, or any planar shapes drawn by AUTOCAD software.
The laser welding machine is highly automated and the welding process is simple. The non-contact operation method can meet the requirements of cleanliness and environmental protection. Using laser welding machine to process workpiece can improve work efficiency. The finished workpiece has beautiful appearance, small weld, large welding depth and high welding quality. The laser welding machine is widely used in the processing of dental dentures, keyboard welding, silicon steel sheet welding, sensor welding, battery seal cover welding and so on. However, laser welding machine has high cost and high precision requirements for workpiece assembly, which still has limitations in these aspects.
