Application Status of Domestic PAUT Technology in Aluminum Alloy Welds

With the widespread use of aluminum alloy material, the application of Phased Array Ultrasonic Testing (PAUT) technology as an advanced digital testing means is attracted much attention. In recent years, under the combination of advanced ultrasonic technology development and application needs, the relevant test researches are successively conducted to provide guidance and standard guidance and to form the relevant industry application standards for PAUT technology of aluminum alloy friction stir welding welds. The application needs of PAUT technology in aluminum alloy gas shielded welding emerges gradually, but the relevant research and standards are still in the initial stage. The application status of domestic PAUT technology in aluminum alloy welds are sorted out, which can provide technical basis for promoting the research of PAUT technology in aluminum alloy welds and expanding the application scenes.
