Final Thesis Investigation of Laser Beam Welding in

The number of fuel cell electric vehicles registered worldwide will increase tenfold by 2030, resulting in an enormous increase in demand for hydrogen. The electrolyser cell is a power-to-gas technology and offers the possibility of converting natural energy into hydrogen.An important manufacturing step of an electrolyser cell is the welding of bipolar...

In cooperation with the Chair of Laser Technology LLT, the Fraunhofer Institute for Laser Technology ILT offers the opportunity to write a thesis. The trend towards hydrogen technology requires the efficient production of bipolar plates. A gas-tight plate is produced from two stainless steel half-shells. Due to the complex contour and long connection, laser...

Due to its physical and mechanical properties, cast aluminum is versatile and can be used in almost every industry. Depending on the casting process, however, cast aluminum alloys can only be welded to a limited extent. Weld spatter formation, weld pool ejections, crack and pore formation can lead to rejection of the material bond, which is why welding cast...

In cooperation with the Chair of Laser Technology LLT, the Fraunhofer Institute for Laser Technology ILT offers the opportunity to write a thesis.

The conventional production of optics is very time-consuming and costly in terms of shaping and polishing. The urge for inexpensive, individualized components therefore requires new manufacturing technologies. One such approach is the use of laser radiation to ablate the glass layer by layer and then polish it by remelting. The two sub-processes are carried...
