The Application of Jet-flow Coupling to Ultrasonic Automatic Testing of SAWH

This article analyzes the advantages of jet-flow based on the comparisonof jet-flow and water membraneused in ultrasonic automatic testing. It verifies the reliability of jet-flow coupling to ultrasonic automatic testing of SAWH by test and summarizes control points of jet-flow coupling, the paper shall provide a reference basis for the application of jet-flow coupling to ultrasonic automatic testing of SAWH.
