| description | A method for setting up a transparent confinement media nozzle (123) for flowing the confinement media (121) during laser shock peening (LSP) of a work piece (108) includes the following steps: Step A) flowing a confinement media (121) and setting a flow rate of the confinement media through a confinement media flow nozzle (123); Step B) positioning the nozzle (123) to flow the confinement media through the nozzle (123) and onto the correlation surface (154); and Step C) measuring a confinement media layer thickness (T) on the correlation surface (154) using an ultrasonic transducer (20) attached to a side (148) of the test piece opposite that of the correlation surface (154). One embodiment of the invention employs the work piece (108) as the test piece and the correlation surface (154) is a first laser shock peening surface (154) on a first side of the work piece (108). Further embodiments includes Step D) comparing the measured and recorded confinement media layer thickness (T) from Step C) against a predetermined value or range of values for confinement media layer thickness (T) and Step E) determining whether to reset the confinement media flow rate and/or nozzle position or proceeding with the laser shock peening (LSP) of the work piece (108) with the confinement media flow rate and nozzle position set in Step A) based on the comparison in Step D). |
