Laser direct joining of metals and polymers using modulated cw laser radiation – one beam source for two processes
Laser direct joining of metals with polymers is based on two main processes: The surface structuring of the metallic joining part and the melting of the thermoplastic joining partner at the interface. Up to now, usually...
Long-term properties of butt fusion welds on gas pressure pipes made of unplasticised Polyamide 12
The unplasticised Polyamide 12 (PA-U 12 ) “Vestamid NRG 2101 ye” (ye stands for yellow) (Evonik Operations GmbH, Marl) is a PA-U 12 180 certified for pipeline construction according to ISO 16486-1, ISO/TS 16486-7 and DVG...
Joining amorphous thermoplastics with the aid of vacuum ultraviolet radiation
This article presents a joining procedure which is based on using vacuum ultraviolet (VUV) radiation for the activation and modification of plastic surfaces. Thus, it is possible to achieve high bonding strengths at temp...
