Development of a simulation model for high-speed welding using laser radiation

Bachelor thesis or Master thesis

In laser transmission welding, plastic parts are joined together with a material bond. Parameters such as the laser power and the irradiation time have a decisive influence on the weld seam quality. For a better understanding of the interaction time between laser radiation and the plastic during welding, the influence of the process speed must be examined more closely, as this has only been estimated to date. In this context, research is currently being carried out into a high-speed welding process. Productivity can be increased by reducing the irradiation time and increasing the laser power at the same time.

As part of a public research project, the possibility of high-speed laser welding is to be investigated, looking at speeds and laser powers that are far above the established range. For this purpose, the high-speed welding process is simulated in this work.

Objective:

The aim of your work is to analyse the processes involved in high-speed welding using a new simulation model you have developed.
