Laser plastic welding is the processing method of plastic, which generates heat energy at welding interface by laser light and melt plastic in a non-contact manner. This is attracting attention due to the dissemination of high power semiconductor laser. Typical welding methods are Laser Transmission Welding Method and Laser Penetration Welding Method (=Absorbance Control Welding (ACW®)). These methods allow high-speed, high-strength and highly-waterproof welding, and are used as new processing methods in the automotive and electronic industries.
If both plastic absorb laser light, heat generation occurs only at the surface where laser light is absorbed and the plastic are not welded.
