Automatic Quality Control of Welding Seams

Welding Seam Analysis Project (original)

Automatic quality control of welding seams

Ateleris team members were involved in selecting image processing algorithms for the detection of welding seams and their automatic quality control evaluation.

In an assembly step of a Swiss high-tech company, tiny metal pieces are contact welded together, and every welding seam is manually analyzed with a microscope. With this process, the company ensures its high-quality standards.

Team members at Ateleris developed algorithms that automatically analyze the high-resolution images and then detect and evaluate the welding seams’ quality. The detection algorithm had to be flexible enough to produce accurate results for various material combinations and potential discoloring. The algorithms proved to be more precise than manual evaluation.
