Title: Shigeaki Matsumoto: Innovator in Ultrasonic Flaw Detection Technology
Introduction
Shigeaki Matsumoto is a notable inventor based in Amagasaki, Japan. He has made significant contributions to the field of ultrasonic flaw detection, holding 2 patents that enhance the efficiency and accuracy of flaw detection in welded structures.
Latest Patents
Matsumoto's latest patents include a fully automatic ultrasonic flaw detection apparatus. This innovative device is designed for convenient flaw detection in weld zones of welded iron structures. The apparatus features a scanner that moves an ultrasonic transmitting and receiving probe in both parallel and perpendicular directions relative to the test piece. An information processing unit controls the scanner's actions and processes the reflected ultrasonic wave data. The probe alternates its movement according to a predetermined routine, allowing for rough flaw detection, with results produced as output. If a flaw is detected, the probe returns to the necessary position for precision flaw detection.
Another significant patent is the method and apparatus for automatic ultrasonic flaw detection of pipe welding zones. This invention divides the width of the weld zone into multiple subdivisions, displaying the ultrasonic energy received from each subdivision using multichannel gate circuitry. The outputs are synchronized with the probe's longitudinal and lateral positions along the pipe. The height of defective echoes is printed alongside the probe positions, and a computer diagrams the defect locations. This method enables high-speed data processing and reduces the time required for precise flaw detection compared to conventional manual methods.
