Abstract

Device for panoramic radiography of welds in metal tubes, such as oil pipelines, comprising a mobile system powered by batteries, provided with an internal radiation source required to carry out the radiography in the area of the weld and capable of being stopped from the outside by by means of a second radiation source acting on a GM counter, characterized in that the mobile system is self-adjusting and when the external source acts on the Geiger counter, conveniently collimated with said source, the mobile system stops and the subsequent separation of the source launches a programmed system that governs the pre-exposure operations of the internal radiation source for radiography, extracting this source from the safety zone to the exposure area, maintaining the source's exposure for a specified time in one area properly focused ahead of the weld, returning the weld Enter the safety zone, restarting the mobile system from its stop position in the normal direction of travel, and an acoustic device that distinguishes the different operations by means of special acoustic signals is activated during this operation.
