Abstract
PURPOSE:To suppress a woods-shaped echo noise, by performing a deflecting scanning before and after an angle of incidence of longitudinal waves adapted to the characteristic of a welded part by electronic scan type ultrasonic flaw detecting method and focusing a beam to a flaw detection part to detect flaws. CONSTITUTION:A delay time controller 4 causes oscillators 1, which are selected by a program, to radiate ultrasonic waves at every prescribed repeat period in accordace with a delay time set in accordance with the transmission direction and the focusing distance of ultrasonic waves by a computer 5. A receiver 3 receives the signal of a selected oscillator by a command of the computer 5 and inputs this signal to a high-speed A-D converter 6. A start time of conversion is set by the signal of a delay controller 4, and the waveform made into a digital signal is inputted to a digital adder 7, and waveforms of selected m-number oscillators are added digitally. By this constitution, the ultrasonic wave transmission and receiving directions and ultrasonic wave focusing distance are changed on occasion to detect flaws, and the sectional image in a material to be checked is displayed on a cathode-ray tube by a picture display equipment 8.
