Abstract
A method for analyzing a weld seam formed by a laser welding process includes thermally exciting the weld seam by radiating at least one laser pulse onto the weld seam, acquiring a decay characteristic of a thermal radiation emitted by the weld seam, and determining whether a welding defect is present based on an evaluation of the acquired decay characteristic.
