Plastic welding is to soften or melt the plastic interface by heating. After a certain pressure and time, the polymer molecular chain diffuses through the interface to form chain entanglement, and finally get the strength of the solder joint
According to the heating method used, plastic welding methods can be divided into external heat and internal heating. External heating uses heat conduction or convection heating of the welded surface. Internal heating is the use of processes to heat the inside of a material in place of external heat sources, including electromagnetic heating and mechanical heating. Compared with other welding methods, electromagnetic heating method produces small vibration force and thermal stress, that is, after welding welding parts are more stable, aging speed is slower, more suitable for precision instruments or easily damaged products.

Compared with other welding methods, the vibration force and thermal stress generated by laser welding in electromagnetic heating method is small, that is, the welded parts are more stable, aging speed is slower, more suitable for precision instruments or easily damaged products such as medical instruments or power electronic devices manufacturing. Therefore, laser welding technology with its small deformation, small heat-affected zone, weld smooth and beautiful, slow aging speed and weld precision, firm and sealed advantages, for the industrial production can not be processed in a single shape and structure of the complex plastic products to provide a new technical means.
Advantages of plastic laser welding
At present, domestic welding technology is more common friction welding, ultrasonic welding and hot gas welding, compared with the traditional plastic welding technology, plastic laser welding technology has the following advantages:
(1) The heating and cooling speed is very fast, which greatly reduces the thermal stress and vibration stress of plastic products.
(2) Laser welding is simple to control, belongs to non-contact processing, strong adaptability, for complex structure or small welding parts have strong operability.
(3) With the continuous upgrading of laser welding equipment, its cost is further reduced and its performance is constantly improved. Compared with other welding equipment, it has the advantages of easy maintenance, convenient operation and long-term use.
(4) After laser welding, the quality of the welds is good, the weld is firm, precise, stable, and the welding process does not produce pollution, is a very environmentally friendly welding technology.
(5) Laser welding, strong applicability, can be welded in a variety of conditions and can ensure the quality of the welding parts, such as in vacuum, air or a medium environment, but also through transparent plastic welding on the contact surface of the welding parts.
