Laser spot welding is one of the important aspects of the application of laser material processing technology. The spot welding process belongs to the heat conduction type, that is, the laser radiation heats the surface of the workpiece, and the surface heat is directed to the internal diffusion through heat transfer. By controlling parameters such as the width, energy, peak power, and repetition frequency of the laser pulse, the workpiece is melted, forming a specific molten pool.
Laser spot welding advantages.
1. Hand-held welding gun replaces the fixed optical path before, which is more flexible and convenient, realizes long-distance laser welding, and overcomes the limitation of worktable travel space.
2. Hand-held welding joints are light and flexible, easy to operate, and can meet the requirements of welding at various angles and positions.
3. The hand-held welding head can be equipped with imported optical fibers of 5 meters/10 meters, which is flexible and convenient for outdoor welding.
4. Infrared positioning is used to correct the position of welded joints and verify the position of welded joints. The position of welded joints is more accurate and the weld seam is more beautiful.
This laser spot welding is mainly used for repairing holes and spot welding sand holes in gold and silver jewelry, and is widely used for spot welding of micro and small precision parts, such as jewelry, battery nickel strips, integrated circuit leads, clock and watch springs, picture tubes, electron gun assembly, and other fields.
