Abstract
An ultrasonic flash gauge is disclosed that provides a profile of a weld area in order to determine inside flash conditions in a pipe. The flash gauge is capable of operating at high temperature conditions adjacent to a electric resistance welder, thereby permitting real time control of the inside flash trimming operation. A focused ultrasonic transducer is employed in order to obtain the resolution required for detecting the profile of the flash. The flash gauge is constructed to uniformly maintain a water column between the transducer and the pipe surface to prevent boiling or air bubble entrapment which would interfere with the operation of the transducer.
