Abstract:
A method for setting up a transparent confinement media nozzle for flowing a confinement media during laser shock peening of a work piece, said method comprising the following steps for at least one point on a correlation surface of a test piece related to one patch of the work piece to be laser shock peened:A) flowing the confinement media and setting a flow rate of the confinement media through the confinement media flow nozzle,B) positioning the nozzle to flow the confinement media through the nozzle and onto the correlation surface, andC) measuring a confinement media layer thickness on the correlation surface using an ultrasonic transducer attached to a side of the test piece opposite that of the correlation surface.
