Laser welding has many advantages. Laser welding can reduce the amount of heat required to the minimum. The range of metallographic changes in the heat-affected zone is small, and the deformation caused by heat conduction is also very low. There is no need to use electrodes, and there is no concern about electrode contamination or damage. The laser beam is easy to focus and correct. Accurate and guided by optical instruments, it can be placed at an appropriate distance from the workpiece, and can be redirected between machines, tools or obstacles around the workpiece. Other welding rules cannot function due to the above-mentioned space restrictions. The workpiece can be placed in a closed In a small space, the laser beam can be focused on a small area and can weld small or closely spaced components. In addition, laser welding has a wide range of weldable materials. It can join various heterogeneous materials with each other, and it is easy to perform high-speed welding with automation. It can also be digitally or computer-controlled. When welding thin materials or fine-diameter wires with laser, it will not be like an arc. Welding is prone to remelting problems, and laser welding is not affected by magnetic fields and can accurately align welding parts.
