Abstract:
A metal piece, having first side and a second side, produced by the method of:laser peening all or a portion of the metal piece from the first side by directing at least one laser beam onto the metal piece from the first side creating a multiplicity of pressure pulses in the metal piece, operatively connecting an acoustic coupling material to the second side of the metal piece coupling said multiplicity of pressure pulses out of the metal piece from the second side, and maintaining said fluid acoustic coupling material operatively connected to the second side of the metal piece throughout said step of operatively connecting a fluid acoustic coupling material to the second side of the metal piece coupling said multiplicity of pressure pulses out of the metal piece from the second side, wherein said fluid acoustic coupling material functions to couple said multiplicity of pressure pulses out of the metal piece into said fluid acoustic coupling material throughout said step of operatively connecting a fluid acoustic coupling material to the second side of the metal piece coupling said multiplicity of pressure pulses out of the metal piece from the second side.
