Abstract

A process for the non-destructive determination of the quality of a weld seam, the process steps comprising: providing a first and a second component; connecting the first and second components by a weld seam produced by a welding operation; and measuring a surface temperature of the weld seam and surface temperatures of areas of the first and second components adjacent to the weld seam that were heated by the welding operation. A system for carrying out the process for the non-destructive determination of the quality of a weld seam, the system comprising: a measuring device, an analyzing unit, and a welding device.
