Welding principle and classification
As a heat source for welding and welding, laser has the advantages of excellent collimation, high beam energy density, small acting area, fast temperature raising speed, fast condensation, etc. In the welding process, the laser beam is acted on the area to be welded through the optical path system composed of transmission or energy fiber, and the plastics in the thermal acting area are melted each other. The melted material forms a new interfusion material, so that the welded parts are connected, laser welding is divided into welded joint type or galvanometer type, and the light source is mainly semiconductor and optical fiber.

1. Laser butt welding
The two light-tight plastics are welded together by melting the two materials at the same time through laser condensation.
2. Laser penetration welding
One kind of plastic is transparent, the other kind of plastic is opaque, and the laser transmits through the opaque plastic junction, forming a melt pool at the junction of the two materials and welding together.
3. Laser mechanical composite welding
After laser butt welding, mechanical compression is added to make the welding surface smooth and smooth.
