Claims

[Scope of utility model registration request]

A hollow cylindrical probe holder that receives water, which is a medium for ultrasonic propagation, is rotated on its central axis, and the round rod or pipe of the material to be examined passes through the probe holder and advances straight. During transportation, in a rotating ultrasonic flaw detection device that ultrasonically detects flaws over the entire surface of the test material, an appropriate length is placed on the inner diameter surface on the inlet side of the probe holder, and the length is the same as the axial direction or Fluid resistance protrusions that extend at a slight angle are sequentially arranged over the entire circumference, and in addition, the extended portion faces the inner diameter surface on the entrance side on the outside in front of the inlet, so that the entire circumference is extended at a slight angle. A rotary ultrasonic flaw detection device equipped with a water supply guide, characterized in that a water supply auxiliary ring is provided which forms a slit in the slit and causes the supply water to be ejected from the slit toward the inner diameter surface on the inlet side.
