Abstract
A method of inspecting the H1 weld between the shroud head flange and the upper shroud section utilizing ultrasonic scanning includes the steps of positioning a phased array ultrasonic probe on a top surface of the shroud head flange, emitting an ultrasonic beam from the ultrasonic probe, electronically steering the ultrasonic beam to scan the weld joining the shroud head flange and the upper shroud section with the beam moving from an outer surface of the shroud head flange to an inner surface of the shroud head flange, and acquiring scan data over the length of the scan. The ultrasonic probe is moved circumferentially along the top surface of the shroud head flange in increments of between about 0.05 inch to about 0.5 inch with the H1 weld ultrasonically scanned after each incremental move.
