Determining grade of weld seam of connected components, comprises detecting electromagnetic radiation emitted during creation of weld seam, comparing values of borderline sample, and determining partial welding depth of weld seam

摘要

The method comprises detecting an electromagnetic radiation emitted during the creation of a weld seam (5), comparing values of a borderline sample, determining a partial welding depth of the weld seam based on accomplished comparison between seized emitted electromagnetic radiation and the comparison values, and connecting by the weld seam a first copper component (3) with a second aluminum component (4). An independent claim is included for a device for determining a grade of a weld seam of two connected components that are formed from various materials.
