Abstract

Procédé de contrôle de différents objets, notamment de soudures, à l'aide de rayons selon lequel on installe une source de rayonnement à une certaine distance de l'objet à contrôler et l'on applique sur la face de l'objet, opposée à cette source de rayonnement, un film sensible aux rayons émis par cette source, après quoi l'objet et, à travers lui, le film sont irradiés par ces mêmes- rayons, lequel film est finalement développé, ce procédé étant caractérisé en ce qu'un collimateur en forme de fente, est intercalé entre la source de rayonnement et l'objet à examiner et en ce que, pendant le processus de l'irradiation, la source de rayonnement et la fente effectuent des mouvements synchronisés le long de l'objet à examiner, ainsi que dans le sens approximativement perpendiculaire à la fente alors que cette source de rayonnement effectue, simultanément un mouvement de va-et-vient le long de ce même objet à examiner et parallèlement à la fente.Method of checking various objects, in particular welds, using rays according to which a source of radiation is installed at a certain distance from the object to be checked and is applied to the face of the object, opposite to this source of radiation, a film sensitive to the rays emitted by this source, after which the object and, through it, the film are irradiated by these same rays, which film is finally developed, this method being characterized in that a slit-shaped collimator is interposed between the radiation source and the object to be examined and in that during the irradiation process the radiation source and the slit effect synchronized movements along the object to be examined, as well as in the direction approximately perpendicular to the slit while this source of radiation performs, simultaneously a back and forth movement along this same object to be examined and parallel to the slit.
