Study on Thermoplastic Materials and Absorbing Agent in Laser Transmission Welding

Abstract

Laser transmission welding of plastics is a joining technique which permits the welding of plastic parts with low process inherent thermal and small welding heat response area. It has high demand of process parameters and material characteristic. In order to study thermoplastic materials properties and ir-absorbing agent in laser transmission welding, experiments were taken under the same process parameters. The YAG laser Output power 200W, working distance 25mm, movement speed 10mm / s. Through the experimental results, we concluded that the different welding quality of different materials and absorbing agent, and analyzed its material characteristic reasons.
