With the advent of the era of optical fiber laser, the application level of laser technology is gradually moving towards a new level, which makes laser technology more prominent in the field of processing and manufacturing, high efficiency and wide range. Laser welding machine plays an important role in the processing and application of precision parts. Let's take a look at the application advantages of laser welding machine in precision parts. Laser welding machine is one of the welding equipment and one of the most important welding methods applied and developed in recent years. Laser welding uses high-energy laser pulses to locally heat the small area of the workpiece. The energy radiated by the laser is guided to the interior of the workpiece through heat transfer, and the workpiece is melted to form a specific molten pool, because the laser welding power density is high and the energy is released quickly, Therefore, the processing efficiency is much higher than the traditional welding method.
