DISPOSITIVO PARA EL CONTROL DE CALIDAD DE UNA UNION SOLDADA POR RESISTENCIA

摘要

An arrangement for quality testing a resistance welded connection in which a radiation detector is directed onto a welding place and receives the emitted radiation; the inlet opening of the radiation detector is at least approximately completely covered off during the welding operation, properly speaking, and is freed after termination of the welding operation. A protection of the radiation detector against weld spatterings is achieved therewith.
