Abstract

Welding method and apparatus for detecting the penetration depth of an electron beam weld, in which X-rays which occur are guided through several plates of an absorption device to a ray receiver, the plates comprising of plurality of bores of equal diameter, which are arranged in their position to one another in such a way that the center lines of corresponding bores on the same level are in exact alignment and that the ray receiver, absorption device and workpiece are aligned in parallel with one another and are co-ordinated to one another in height.
