Abstract: The invention relates to a system for the nondestructive testing of metal fusion welds at thin-walled pipes having a maximum wall thickness of 6 mm. It is formed with at least one test probe for the emission and detection of soundwaves as well as with at least one adjustment body which is composed of a material which is the same or a material having at least approximately the same acoustic properties as the respective pipe to be tested. The outline dimensions and the diameters/thicknesses of the adjustment body are at least approximately the same as those of the respective pipe to be tested. A plurality of blind bores each having different lengths/depths starting from their openings to their bases are formed in the adjustment body.
