RODRIGUEZ, Jairo; VITOLA, Jaime; SANDOVAL, Susana  e  FORERO, Edwin. DESIGN AND CONSTRUCTION OF A SYSTEM FOR NON-DESTRUCTIVE INSPECTION OF FAULTS AND DEFECTS IN METALS USING ULTRASONIC SIGNALS. Rev.EIA.Esc.Ing.Antioq [online]. 2009, n.12, pp.9-21. ISSN 1794-1237.

The present paper describes the design and construction of an electronic system for non-destructive inspection with ultrasound (NDTU), which is one of the most used techniques to evaluate without deteriorating metallic parts in several areas of the industry. The evaluation techniques that appear in this document are Time of Flight Diffraction (TOFD) and pulse-echo, for which, defects in welded metallic unions were incorporated deliberately (test plates). The implemented system consists of two angular transducers according to the technique used in each case, a pulser that suitably feeds the transducer, the methodologies of acquisition and digital processing of the information. In the document, A-Scan and D-Scan graphs that illustrate a typical case of analysis as example are included. Finally, the developed system has demonstrated to be effective, compared with examinations made using a commercial equipment of the same nature, and with another technique of inspection like radiography.

Palavras-chave : NDTU; pulser; transducer; welded unions; TOFD; pulse-echo; A- and D-Scan.
