Identificação e avaliação de descontinuidades em juntas soldadas utilizando ultrassom com visualização A-Scan – Maior eficiência em comparação com outros ensaios

Abstract

Among the known methods of inspecting the equipment that stand out are best known as NDT nondestructive testing. The test is an ultrasound NDT that can be considered as the most practical and widely used, with relative ease of application and immediate report. He is employed in the analysis of welded and predictive evaluations in their daily use in field structures. Objective with this study demonstrate that the differentiation of discontinuities found in welded joints by ultrasonic testing is much more accurate compared to the other END because it can accurately measure and locate the defect in the tested piece, unlike the test radiography can only tell whether or not a discontinuity. Whether in repair of process equipment, fabrication of vessels and metal parts used in large machines, service inspection techniques with ultrasound are widely used in petrochemical, oil, nuclear and naval. To construct this work we take as an example the stereo display with type A-Scan and angle heads.
