Shown in the possibility of autonomous movement of X-ray units and solid-state radioscopic transducers on magnetic platforms, which makes nondestructive radiation testing more informative. Described are the principles of construction of new technologies for quality control of welded joints in complex metal structures and main pipelines, which can be successfully transferred to critical tubes of thermal and nuclear power stations. Replacement of film radiography by portable radioscopy (X-Ray-TV), using mobile CCD-detector will widen the area of flaw detection application in industry. Examples of manufacture and application of radioscopic detectors are given, the cost of which is by an order of magnitude lower than that of standard plane-parallel transducers. 21 Ref., 15 Fig.
Keywords: radiation filmlesss control, circumferential welds, pipelines, magnetic platform, radioscopic transducer, CCD-matrix, Wi-Fi, video camera, plane-parallel and miniature transducers
