Abstract
Polymers show several application orientated advantages such as:This in turn allows innovative product design and new products. But, new fields of application and enhanced demands require innovations in materials processing. Laser technology opens new manufacturing possibilities. Laser welding of thermoplastic polymers provides several process technical advantages:Applications of laser welding of polymers are found in several fields of industry, already :Different welding strategies are available, such as serial, mask, quasi-simultaneous and simultaneous welding, while each offers characteristic dis- and advantages. Therefore, the appropriate strategy can be adapted to the current application.Both scientific and application orientated results concerning laser penetration welding of polymers using high power diode laser are presented in brief. Experimentally obtained results concerning strength of the weld seams as well as the gap bridging capability are presented while comparing it for different process strategies. Furthermore, results from thermodynamic process modelling are illustrated. The modelling considers different steps of approximation up to a complete solution of the real joining geometry while considering the optical properties as well as a gap between the joining partners.Polymers show several application orientated advantages such as:This in turn allows innovative product design and new products.
