Abstract: First of all,the principle of laser welding of plastics is explained.Then,several new methods,characteristics and applications of laser welding of plastics are introduced,such as contour welding,simultaneous welding,quasi-simultaneous welding,mask welding,radial welding,Globo welding and diffractive welding.At last,present status and development trend of laser welding of plastics are summarized.It can be seen that the current study mainly focuses on two-dimension welding,while research on three-dimension welding is scarce.Laser welding of plastics is becoming a hot phenomenon in laser welding field.It might replace the traditional welding methods of plastics.
