NON-DESTRUCTIVE TESTING USING PHASED ARRAYS

Abstract:

A method of non-destructive testing of an article (20) is described. The article has a first surface (21). The article (20) article (20 comprises a set of passageways (200), including a first passageway (200 A). Respective sets of flaws (2000) are associated with respective passageways of the set of passageways (200), including a first set of flaws (2000A), optionally including a first flaw (2000AA), associated with the first passageway (200 A). The method comprises phased array ultrasonic scanning of the article (20) using a phased array probe communicatively coupled thereto through the first surface (21); and detecting the first flaw (2000AA), if included in the first set of flaws (2000A) associated with the first passageway (200A).
