Bachelorarbeit: LLM-gestützte Assistenz zur Extraktion von Förderrichtlinien in der Lasertechnik

The Chair of Laser Technology LLT at RWTH Aachen University, together with the cooperating Fraunhofer Institute for Laser Technology ILT, is Europe's leading center for basic and contract research in the field of laser technology.

The weldability of cast aluminum alloys is currently classified as limited for fusion welding processes. Limitations result from the process-dependent shape and characteristics of the material inhomogeneities in the base material, which vary depending on the process (sand mold casting, gravity die casting, die casting). In particular, the presence of gas pores and blowholes leads to increased porosity of the weld seam during the joining process and to weld pool ejections, which can have a negative effect on the quality of the welded joint and lead to rejection of the material bonded joint. The motivation is to develop a fundamental understanding of the interactions between the material inhomogeneities in the base material and the laser-based joining process.

Was Du bei uns tust

• The focus of your research work will be on analyzing the causes of weld pool ejections during laser beam welding and deriving preventive measures.
• Depending on the focus, your tasks will include
  • Literature research, metallographic analyses and microscopy
  • Carrying out and evaluating welding tests (with and without beam shaping)
  • and/or the theoretical/simulative analysis of weld pool ejections (physical explosion model)

Was Du mitbringst

• You are studying engineering, materials science, physics or a comparable course of study
• Independent, organized and structured way of working
• You have basic knowledge in the field of materials science
• Experience in laser beam welding of aluminum-based alloys is advantageous, but not mandatory

Was Du erwarten kannst

👥 Team spirit: Creative, interdisciplinary environment with a motivated team, flat hierarchies and a “you” culture.
🖥 Workplace: Excellent machinery and equipment as well as first-class office facilities.
💪 Co-creation: Practice-oriented final thesis in an innovative applied research environment.
🧘‍♀️ Work-life balance: Benefit from flexible working hours on a trust basis.
➕ Advantages: Opportunity to benefit from exciting corporate benefits.
🚐 Travel: Good transport connections, parking spaces directly in front of the institute, an e-charging station and a parking garage.
