A stud bolt an automatic inspection supersonic waves probe

摘要

A supersonic inspection probe for a stud bolt is provided to accurately detect a position of a defect on the stud bolt by automatically inspecting the stud bolt using a scanner. A supersonic inspection probe for a stud bolt includes a supersonic oscillator(74), a semispherical oscillator housing(74a), and a sensor housing(71). The supersonic oscillator includes plural supersonic units(74-1) which are laminated in a width direction. The semispherical oscillator housing receives the supersonic oscillator therein. The sensor housing is coupled with the oscillator housing. An end portion of the sensor housing forms a tapered surface having a small diameter.
