Abstract: A delay line is configured to acoustically couple a phased array transducer to a workpiece. The delay line includes a delay line bottom portion, a delay line end portion, and a delay line top portion. The delay line bottom portion has a delay line flat surface. The delay line end portion is contiguous with the delay line bottom portion and has a delay line curved surface extending upwardly from the delay line flat surface at a delay line transition point between the delay line curved surface and the delay line flat surface. The delay line top portion has an array mounting surface configured to support a phased array transducer in a manner such that ultrasonic waves emitted by the phased array transducer pass through the delay line and exit along the delay line flat surface at least up to the delay line transition point.
