Abstract
Provided is a water jet peening apparatus and a water jet peening method including: a clamping cylinder () which is able to be disposed at the outer peripheral side of an instrumentation nozzle () with a predetermined gap therebetween; a clamping piece () which is able to fix the clamping cylinder () to the instrumentation nozzle (); a nozzle guide () which has a cylindrical shape, is provided inside the clamping cylinder (), and is positioned to a position adjacent to the upper end of the instrumentation nozzle (); an inner surface WJP nozzle () which is movable upward and downward inside the nozzle guide (); and a drainage hole () which radially penetrates the nozzle guide (). Accordingly, it is possible to improve the safety of the operation by preventing a thimble tube from being popped out due to a water jet peening operation.
