Laser laser welding - rapid development of laser welding
Rapidly developing laser welding technology The basic principle of laser welding plastic is to superimpose two workpieces by pressing the clamp, and then inject laser into the upper workpiece so that the laser can penetrate the workpiece and be absorbed by the workpiece below. The absorbed laser light energy is converted into heat energy, which in turn causes the contact faces of the two workpieces to melt, eventually forming a weld zone. However, it is true that the application of laser...
