Abstract:
The report describes the use of the Delta Configuration with a dual oscillating transmitter, a fixed divergent transmitter and a single oscillating divergent transmitter for inspecting steel butt welds. Schlieren studies of the transmitter configuration are included. The Delta Technique is a multi-search unit method of ultrasonic weld inspection. Incident energy is angled into the weld region from two transmitters positioned transverse to the weld length, one on each side of the weld. Flaw information is received with a third search unit positioned directly over the weld. Flaw information is not dependent on preferred flaw orientation, although the receiver must be directly over the defect. Author
