Abstract (en)

[origin: WO9944784A1] The testing of weld seams obtained by laser welding of a butt joint poses considerable difficulties. According to the invention, to detect welding defects the weld seam length is scanned continuously along the weld seam and welding defects are detected on the basis of excessively raised areas of the weld seam.
