Ultrasonic flaw detection device for tubular steel structure and use method thereof

The invention relates to the field of ultrasonic flaw detection, in particular to an ultrasonic flaw detection device for a tubular steel structure and a use method thereof. The ultrasonic flaw detection device comprises a handheld frame, a fixed mounting frame, a protective frame, sliding push frames and the like; the top of the handheld frame is connected with the fixed mounting frame through bolts, the top of the fixed mounting frame is fixedly connected with the protective frame, and the fixed mounting frame is symmetrically and slidably connected with the sliding push frames. The ultrasonic detector rotates around a to-be-detected tubular steel structure, and the ultrasonic detector is attached to the to-be-detected tubular steel structure, so that the ultrasonic detector conveniently performs flaw detection on the to-be-detected tubular steel structure by utilizing ultrasonic waves, the detection is relatively comprehensive, and omission is not easily caused. 本发明涉及超声波探伤领域，尤其涉及一种管状钢结构的超声波探伤检测装置及其使用方法，包括有
