Due to the manufacturing process and material properties, transmission variations along the welding path appear in the transparent joining partner which can decisively influence the welding process. Thus, there can be an increased reflection and therefore reduced transmission of the laser radiation in regions of e.g. accumulated glass fiber content. As a result, this area will be affected by an increased energy loss, so that only a reduced amount of laser energy will be available for the actual welding process. By using the appropriate Intego system, the transmission profiles are determined. Accordingly, with knowing these profiles the welding technology of Evosys Laser GmbH enables the customer to adjust the process to the locally varying transmission characteristics of the plastic component. This leads to a constant energy input of the joining process and a consistent high quality of the weld seam. With our PICTOR system we offer you solutions for the:
