所望の溶接継ぎ目線に関する実際の溶接継ぎ目線の横ずれを監視する方法、構造体及び自動車用シート

摘要

The invention relates to a method for monitoring a lateral offset of an actual weld seam configuration relative to a desired weld seam configuration, in particular in the motor vehicle sector, comprising the following steps: a) providing at least a first structural part having a geometric deviation in the region of the desired weld seam configuration; b) guiding a laser beam along the first structural part to produce a weld seam, forming a melt pool, thereby producing the actual weld seam configuration; and c) detecting a reflection from the melt pool simultaneously with step b).
