Three positions of the contact type of transducer along the zigzag scanning path used during the manual angle-beam ultrasonic inspection of welded joints. The movement of the sound beam path across the weld is shown on a section taken along the centerline of the transducer as it is moved from
a) the far left position in the scanning path
Angle-beam inspection of a weldment showing effect of search-unit movements on oscilloscope screen display patterns from three different types of flaws in welds. a) Positions of search units on the test piece. b) Display pattern obtained from a gas hole as the result of traversing the search unit in an arc about the location of the flaw. c) Display pattern obtained from a slag inclusion as the result of swiveling the search unit on a fixed point. d) Display pattern obtained from a crack, using the same swiveling search-unit movement as in
Sizing based on time of flight Uses two probes- one transmitter and the other receiver
