CONSIDERATIONS REGARDING OF MECHATRONICS TYPES OF STRUCTURES FOR POSITIONING IN NON-DESTRUCTIVE TESTING
Quality control of welded joints and the structure of materials is made with techniques becoming more efficient. A commonly used class of techniques is known as non-destructive testing (NDT). Among the known NDT variant types in this work are taken under study those based on the principles of radiation emission (X-rays) and ultrasound. Obtaining reliable results, approached in a short time and protected from the effects of disturbance factors depends on different parameters of control techniques. Among these should be mentioned: the correct positioning of the emitter of radiation and the waves , against the weld and / or parts-piece surface, the position control of these parts, so that to be respected the terms of "feeling" and "collision" of the weld and surface, the conditions imposed by the NDT equipment manufacturing company, replacing attributions of human operators in NDT in order to protect them against irradiation etc. In this paper are detailed factual information about these issues. It is insisting on mobile systems designed in view of mechatronics, introduced in the NDT structures.
