As a kind of welding heat source, laser has the advantages of good collimation, high beam energy density, small area of action, fast heating speed and rapid condensation. In the welding process, the laser beam is acted on the welding area through the optical path system composed of optical fiber, the first layer is a transparent layer, the second layer is an absorption layer. When the hot melt zone is formed, the plastics in the thermal zone melt each other. During the subsequent solidification process, the melted material forms a new intermelting material, thus connecting the welded parts.
