Plastic laser welding method: contour welding, simultaneous welding, quasi-simultaneous welding radial welding Globol-welding. As the name suggests, the contour welding is to make the laser move along the weld line of the workpiece, will need to be welded plastic layer melted and bonded together; some cases, the fixed location of the laser, moving or rotating parts to achieve the purpose welding. 

 Synchronous welding the first laser head according to the shape of the welding zone custom requirements of the welding area shape are generally symmetrical, such as round. Synchronous welding laser beam from multiple diode laser beam, they are simultaneously melting the welding area to achieve the effect of welding in the welding of the contour line of the region. Laser beam welding plane through the translucent material of the upper reaches, and then absorbed by the underlying material. The laser energy is absorbed so that the lower material temperature, melting the plastic of the upper and lower, and finally solidified into a solid weld. 

 Mask welding need to make a reflection or absorption of the laser template. The template used to locate the welding area, laser fusion welding area through the template to the effect of welding. Mask welding advantage of its flexibility, the template can change the shape of the weld zone at the same time, this welding method is also applicable to high-precision welding, precision can reach the micron level. Thermoplastic welding process, both to be welded plastic parts by using a clamping fixture are clamped together, one of the plastic parts enables the laser to penetrate, and the other plastic parts can absorb the laser energy. 

 Laser beam through the air cushion can be no arbitrary rolling friction of the glass ball point-like style to focus on the welding interface, the glass ball is not only focused but also act as a mechanical clamping fixture. When the ball rolling on the surface, the joints to provide sustained pressure. This ensures that the laser heating of the material while under pressure clamping. The glass sphere replaces the mechanical fixture, while expanding the scope of application of laser welding in continuous three-dimensional welding.
