ULTRASONIC FLAW DETECTION METHOD, ULTRASONIC FLAW DETECTION DEVICE, AND WELD INSPECTION METHOD FOR PANEL STRUCTURE |
摘要 |
<p>Provided are an ultrasonic flaw detection method and an ultrasonic flaw detection device with which inspection of a weld (404) of a member having a complex cross sectional shape can be accomplished using a computing device that is readily applicable. Also provided are an ultrasonic flaw detection method or an ultrasonic flaw detection device with which inspection of a weld line (210) or a weld (404) of a panel structure formed by welding together members having a complex cross sectional shape can be accomplished using a computing device that is readily applicable. A region of interest ROI (402) for inspection is set in the weld line (210), including a location that allows generation of reflected or diffracted ultrasonic waves produced due to the shape of the member being inspected, and a flaw image (401) of an area including the ROI (402) is acquired and inspected for the presence of welding flaws.</p> |
