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 melted almost simultaneously (i.e. quasi-simultaneously). Due to the simultaneous melting…
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. Due to the radially symmetrical structure of the joining assembly…
In the process variant known as contour welding, the laser beam is moved along the weld seam using a suitable motion system. The feed rates usually range between 0 and 500 mm Due to the relatively slow movement of the laser beam, material is only partially heated, melted and welded.…
When laser welding plastics, a distinction can be made in principle between butt welding and transmission welding according to the joint geometry. In industrial applications, mainly transmission welding is used. Here, two plastics with different absorption properties, which are caused by different filler types or concentrations, are welded in a…
