Utilização do phased array em substituição a radiografia convencional na fabricação de vasos conforme código asme

Abstract

The pressure vessels have wide use in industries of different segments, in the early twentieth century was created with the objective of regulating safe standards of manufacture of pressure vessels, the ASME code. Radiography has been practiced as the primary non-destructive technique for examining welded joints of pressure vessels for decades, but over the years, newer, more efficient, faster, and cheaper techniques have begun to appear on the market. One of these techniques is the phased array ultrasonic test, which uses a matrix with multi-transducers excited individually, which allows a scan at different angles, providing this method advantages over conventional ultrasound. This work seeks to analyze the advantages and disadvantages of the ultrasonic inspection technique Phased Array compared to the radiography in the manufacture of pressure vessels ASME, using the code case 2235.
