An essential component for a robust process is the design of the joining zone. Basically, a distinction can be made between process-independent and process-dependent criteria. The following criteria and information are generally valid for all process variants. MATERIAL THICKNESS –…
As an alternative to conventional laser welding, laser welding of plastics with wavelengths in the range of 2µm can be used. With this variant, two workpieces can be joined without additional absorbers. The main difference of the process lies in…
In simultaneous welding, the entire weld seam is heated and melted at the same time (i.e. simultaneously) by one or more beam sources. The arrangement of the beam sources or the beam shaping by means of suitable optical elements must…
In so-called quasi-simultaneous welding, the weld seam is repeatedly scanned at high speed with a focused laser beam. The feed rates are usually above 300mm/s up to several meters per second. All areas of the weld seam are heated and…
A special form of contour welding is the variant for processing radially symmetrical assemblies. An essential difference between this special form and the other process variants of laser plastic welding is the application of joining pressure in the joining zone.…
