The development trend of handheld laser welding machine Continuous laser welding is divided into two types: fiber laser welding and semiconductor laser welding. The key difference is that the light spot of the optical fiber is very thin, and the light spot of the semiconductor is relatively large. It can be simply considered that the spot size is different. Fiber laser welding is 2-3 times faster than semiconductors, the key initial light spot is small, the kinetic energy is concentrated, and the welding penetration is good. Laser welding has achieved rapid development in recent years. Fiber laser welding has the advantage of speed, but it requires extremely high product workpieces. The gap is within 20 wires, and it is difficult to guarantee mass production for many hardware processing. To better solve this problem, the shaking fiber laser cutting head appeared. Simply speaking, shaking the laser cutting head is to draw a circle. It will be easier to understand by using a descrip...
