Ultrasonic inspection of partially completed welds using pattern recognition techniques

OSTI ID:5893600
The feasibility of using automated ultrasonic examination with computer-based pattern-recognition techniques to inspect partially completed welds on a pass-by-pass basis is investigated. In these tests welds are inspected, as they are being made, by an automated ultrasonic search unit attached to the weld head. Flaws are intentionally made in the weld. An analysis of the ultrasonic data collected during this process shows that the flaws can be reliably distinguished from good weld and, further, that two different types of flaws can be differentiated from each other. From this analysis a practical concurrent inspection system is shown to be feasible.
