Abstract:
Provided is a method for flaw inspection of a stem joint of a valve including: an internal flaw inspection step including causing a flaw detection probe to be disposed so as to face upward in water in a tank in an ultrasonic inspection chamber, holding a valve in such fashion as to cause the tip to face the flaw detection probe, and inspecting for a flaw at the interior of the stem joint; and a surface flaw inspection step including causing a flaw detection probe to be disposed horizontally in an eddy-current inspection chamber, holding a valve in such fashion as to cause the side face of a stem of the valve to be close to and facing the flaw detection probe, inspecting for a flaw on the surface of the stem joint while the flaw detection probe and the valve are made to engage in mutual rotation. The valves are transferred from a valve loading position to the ultrasonic inspection chamber, from the ultrasonic inspection chamber to the eddy-current inspection chamber, and from the eddy-current inspection chamber to a valve unloading position in substantially simultaneous, continuous, synchronous, and/or coordinated fashion.

Claim (Index 4):
The apparatus for flaw inspection of a stem joint of an engine valve according to  claim 2 , wherein the valve transfer mechanism includes a slide frame movable in a horizontal direction in which the ultrasonic inspection chamber and the eddy-current inspection chamber are adjacent to each other and capable of ascending and descending in a vertical direction, and the valve supports which are integrated with the slide frame.
