摘要： The present invention enables the processing head to locate itself precisely on the surface of the structure being processed, and to then reposition itself correctly for the next laser spot. Further, the present invention will complete processing a laser peened area, the area including a multiplicity of spots arranged in a specific pattern, and correctly laser peen each spot in the area under control of a controller including control linkages with the laser.The invention further provides an automated laser peening processing head encompassing spatial position sensing and locating means, as well as programmed spatial positioning, application of overlay materials, verification of proper overlay condition and positioning, and notification of the laser to pulse the surface of the structure.

摘要： A method of controlling the application of laser peening overlays on the surface of a workpiece to reduce the variability of shock waves generated therein, comprises applying an energy-absorbing overlay to a portion of the surface of a workpiece, measuring the thickness of the energy-absorbing overlay in at least one location on the energy-absorbing overlay, applying a transparent overlay material over the energy-absorbing overlay, measuring the thickness of the transparent overlay in at least one location on the transparent overlay, determining if the measured values for each overlay is within a specified range, and directing a pulse of coherent energy to the workpiece to create a shock wave therein when the measured values are within the specified range.

摘要： Various laser shock processing systems are provided to establish selective compressive residual stress distribution profiles within a workpiece. An asymmetrical stress profile may be formed through the thickness of a thin section of a gas turbine engine airfoil. One system is configured to simultaneously irradiate a workpiece with a set of laser beams to form a corresponding set of adjacent non-overlapping laser shock peened surfaces, enabling the shockwaves to encounter one another. Another system irradiates opposite sides of the workpiece at different times to form opposing laser shock peened surfaces, enabling the shockwaves to meet at a location apart from the mid-plane. Another system simultaneously irradiates opposite sides of the workpiece using laser beams having different pulse lengths to form opposing laser shock peened surfaces. Another system simultaneously irradiates opposite sides of the workpiece to form a set of laterally offset laser shock peened surfaces.

摘要： A laser shock processing apparatus with controller for controlling laser shock processing operation. The controller generates an operator perceivable alert when a processing value is not within a predetermined range of a preset value. The controller may adjust the processing value to be within the predetermined range or may deactivate a laser from directing a beam of coherent energy to a workpiece. In one embodiment, a plurality of controllers comprise distributed processing of various processing values for controlling laser shock processing operation.
