Thesis on defect detection during the welding of thin stainless steel foils

In cooperation with the Chair for Laser Technology LLT at RWTH Aachen University the Fraunhofer Institute for Laser Technology ILT, Europe's leading center for contract research and development in the field of laser technology, is offering the opportunity to write a thesis in the “Joining of Metals” department.

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 welding is used here. The challenge lies in detecting welding errors during the process. A process monitoring system provides a suitable tool for this. 

What you will do

• You detect defects in the weld seam and can exclude defective components from further production steps 
• You research and record the current state of the art
• You are responsible for independently planning and carrying out welding tests
• You use a process monitoring system and evaluate the results
• The documentation and discussion of the results are also part of your job

What you bring to the table

• You are studying mechanical engineering, physics or a comparable course of study
• You have a keen interest in varied and diverse scientific work in application-oriented research
• You work independently, organized and structured 
• Initial experience in the field of laser technology is an advantage for you, but not essential

What you can expect

• Practice-oriented thesis in an innovative working environment
• A creative and interdisciplinary working environment in a highly motivated team
• Excellent machinery and equipment
• Exciting and challenging areas of work in applied research
• Good transport links (bus connection, free parking garage)
• Flexible working hours that allow you to combine your studies and professional practice

The position is limited until the completion of the thesis.

We value and promote the diversity of our employees' skills and therefore welcome all applications - regardless of age, gender, nationality, ethnic and social origin, religion, ideology, disability, sexual orientation and identity. Severely disabled persons are given preference in the event of equal suitability. 

With its focus on developing key technologies that are vital for the future and enabling the commercial utilization of this work by business and industry, Fraunhofer plays a central role in the innovation process. As a pioneer and catalyst for groundbreaking developments and scientific excellence, Fraunhofer helps shape society now and in the future. 

Interested? Apply online now. We look forward to getting to know you!
