发明名称 Method and apparatus for non-destructive weld testing
摘要 A method for detecting the integrity of a bond of a multi-piece work piece includes capturing a first image of the work piece, stressing the work piece, capturing a stressed image of the work piece, and comparing the first image of the work piece with the stressed image of the work piece to determine the integrity of the bond.

主权项 1. Method for detecting the integrity of a bond of a multi-piece work piece, comprising: capturing a first image of the work piece; stressing the work piece; capturing a stressed image of the work piece; comparing the first image of the work piece with the stressed image of the work piece to identify shear lines indicative of strain in the work piece during the stressing; creating a shear image of the work piece based on the shear lines, the shear image including a node point indicating a location of the bond; comparing the shear image of the work piece to a reference image; and determining the integrity of the bond based on characteristics of the determined shear lines and the node point in relation to the reference image.
