AI weld-position detection for laser welding of EV cell contacting systems
ElringKlinger cut set-up of weld-position detection from days to hours with TRUMPF's image-based AI
Problem
ElringKlinger welds cell contacting systems for electric-vehicle batteries. The parts are up to 2 m long and carry more than 50 weld positions. Getting a reliable image-based detection of those positions used to take days.
Approach
A joining-technology engineer trains TRUMPF's EasyModel AI with VisionLine Detect on a few images. The images go to a cloud, the engineer marks the relevant areas, and the model finds component edges even at short cycle times. No programming is needed. The filter started at the Neuffen future-technologies plant and was rolled out to two more production sites.
Results
Takeaway
Training a vision model on a handful of images let a process engineer, not a programmer, set up detection for long parts with many weld points.
