Abstract

Electric traction motors must meet high requirements in terms of efficiency in driving operation as well as cost-effectiveness in manufacturing. The so-called hairpin technology yields potential for both aspects. However, a central bottleneck in hairpin stator manufacturing is the contacting process, commonly performed by laser welding, where a large number of joints must be created. Since a single defective weld can lead to a failure of the whole stator, effective methods for quality assessment are needed. Building on preliminary work, this paper proposes a novel multi-view deep learning architecture for combined processing of pre- and post-process images to detect welded joints with an insufficient cross-section.
