Abstract
In the automotive industry, new material combinations and optimized designs enable material savings and weight reductions. However, during welding, the different properties of the materials lead to structural changes and in-fluence the strength of the joint. Testing of the resulting intermetallic phase is of crucial importance for safety-relevant components, which currently often requires complex and destructive methods. The aim of the project is to develop a fiber-based, endoscopic LIBS (Laser Induced Breakdown Spectroscopy) system that enables spatially resolved determination of the material composition of welded joints in cavities or complex deep-drawn components of wrought aluminum alloys. The proposed method offers advantages in terms of measurement speed and reduced sample destruction.
