Design layout of the joining zone – Part 2

The following criteria are specifically relevant for the individual process variants and must be taken into account accordingly when it comes to the design layout of the joining zone. CONTOUR WELDING-TOLERANCES – As no relative movement of the joining partners to each other can take place in a contour welding…

Laser transmission – quality can be measured

The laser welding of plastics is dependent on a laser-transparent and laser-absorbing joining partner, which are connected in an overlap weld. While the absorbing properties are usually robustly adjusted by additives and other influences play a minor role, the laser transmission reacts sensitively to various factors. These are, for example,…

Design layout of the joining zone – Part 1

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 – Depending on the material used for the laser-transparent joining partner,…

Clear to clear welding

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 the way the energy is introduced into the plastics to…
