Non-destructive testing method for checking laser welding joints induces an eddy current near a welding joint in a work piece with a welding joint

摘要

A first metal sheet (1) has a 2 mm thickness. A second metal sheet (2) has a 0.8 mm thickness. Both sheets are bonded to each other by means of a welding joint (3), i.e. a laser welding joint produced in a laser welding process. The welding joint has a flawed point (4) in the form of a pore (5).
