Gap Bridging in Laser Transmission Welding of Thermoplastics
Chen, Mingliang (2009-09-26)Contour laser transmission welding (LTW) is a technology that has potential for joining large and complicated thermoplastic parts. Thermal expansion is the primary driving force to bridge potential gaps at the weld. A ... -
Laser Transmission Welding of Polybutylene Terephthalate and Polyethylene Terephthalate Blends
Khosravi, Sina (2010-08-31)Laser Transmission Welding (LTW) involves localized heating at the interface of two pieces of plastic (a laser transparent plastic and laser absorbing plastic) to be joined. It produces strong, hermetically sealed welds ... -
Laser Welding of Alumina Ceramic Substrates with Two Fixed Beams
Sedore, Blake (2013-04-30)Laser welding was investigated as a potential joining technology for alumina ceramic substrates. The objective of this study was to develop a method to preheat the ceramic using a single defocused laser beam prior to ... -
Laser Welding of Nylon Tubes to Plates Using Conical Mirrors
Kritskiy, Anton (2009-08-17)Laser transmission welding of polymers is a relatively new joining technique. It is based on the fact that the majority of thermoplastics are transparent to infrared radiation. A laser beam passes through the transparent ... -
Modelling Laser Light Propagation in Thermoplastics Using Monte Carlo Simulations
Parkinson, Alexander (2013-09-27)Laser welding has great potential as a fast, non-contact joining method for thermoplastic parts. In the laser transmission welding of thermoplastics, light passes through a semi-transparent part to reach the weld interface. ... -
Weld Read-Through Defects in Laser Transmission Welding
Cao, Xiaochao (2010-07-02)In laser Transmission Welding (LTW), the laser beam passes through the transparent part and is dissipated as heat in the absorbent material through the use of laser-absorbing pigments such as carbon black (CB). This energy ...
