The development of handheld laser welding machine

 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 description. Everyone draws a parallel line with a ball-point pen, which is long, slender, and thin; if there is a ball-point pen to draw a circle, draw one immediately, and it will be relatively wider. This basic principle is that the fiber laser shakes the laser cutting head. The laser is continuously drawn in a circle to expand the total width of the seam welding. The grinding time after welding was too long, and the labor cost and consumables cost increased year after year. After laser welding is selected, the seam welding surface is neat and beautiful, which greatly reduces the polishing time. Manpower, grinding, and polishing consumables have also been greatly saved. Hardware polishing and polishing have been an annoying matter in terms of environmental protection in recent years. Laser welding is less polished, and it is easier to implement environmental protection regulations.
