Non-destructive testing of welds. Ultrasonic testing. Use of automated phased array technologyWhat is this standard about? This document specifies the application of the phased array technology for the semi or fully automated ultrasonic testing of fusion welded joints in metallic materials of minimum thickness 6 mm. It applies to full penetration welded joints of simple geometry in plates, pipes, and vessels, where both the weld and the parent material are low alloy and or fine grained steel.
