ABSTRACT:
An ultrasonic linear array water nozzle (10, 10A) wherein water is coupled with ultrasonic energy between linear array transducers (126) and a workpiece (132) under inspection. The nozzle includes a water receiving plenum chamber (22) extending for the length of the nozzle and for the length of linear array transducers. Plenum chamber (22) supplies water immediately downstream of the transducers where water is coupled with ultrasonic energy from the transducers. The nozzle has a main body (88) downstream of the transducers and has downstream water paths in the form of waveguides (190) which are spaced by air gaps (186), the waveguides each extending downstream in the shape of an exponential horn. The waveguides (190), formed by consecutive plates (168) having air gaps (186), are each in respective alignment with an individual transducer (126).
