摘要： A method is disclosed for repairing damage to an airfoil. The method provides for the removal of a section of the airfoil that substantially encompasses the damaged area, which consequently leaves a void and a cut-away surface in the airfoil. A replacement piece larger than the residual void is provided for use in replacing the section removed from the airfoil. A joining operation welds or otherwise joins the replacement piece to the airfoil at the cut-away surface to form a joined airfoil. The joined airfoil has a seam between the airfoil and the replacement piece. At least a portion of the seam is processed by laser shock peening to induce compressive residual stresses therein.

摘要： A bend bar is available for use in a quality control test for testing for a consistency of residual stress effects in a particular material using a given a laser peening process. The bar is composed of the particular material to be tested and has a bar length and a bar thickness. The particular material has a characteristic maximum stress penetration depth for compressive residual stresses that can be formed in using the given laser peening process. The bar thickness is chosen so as to be at least twice the characteristic maximum stress penetration depth. The bar has a test surface that extends parallel to the bar length and perpendicular to the bar thickness. After forming a spot pattern on the test surface using the given laser peening process, the deflection generated in the bar due to the compressive residual stresses induced by laser peening can then be measured and used as a quality control measurement.

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 system for evaluating the integrity of a bonded joint in an article includes a laser configured in a laser shock processing arrangement to perform a laser shock processing treatment on the article. A beam delivery system employs an articulated arm assembly to communicate the radiant energy emitted by the laser to a process head proximate the article. The laser shock processing treatment causes the formation of shockwaves that propagate through the article, inducing internal stress wave activity that characteristically interacts with the bonded joint. A sensor detects a stress wave signature emanating from the article, which is indicative of the integrity of the bond. A detector such as a non-contact electromagnetic acoustic transducer provides a measure of the stress wave signature in the form of surface motion measurements.

摘要： A method of producing a workpiece involves positioning the workpiece at a current processing position indicated by a hard-coded part program and then collecting position data which defines the positional arrangement of a current target area of the workpiece. The collected position data is processed by comparing it to reference position information that represents the positional arrangement of the same target area in an ideal workpiece employed in the development of the part program. The position of the workpiece (and hence the target area) is adjusted in accordance with the comparison results. A laser shock processing operation is performed on the workpiece at the current target area following the position adjustment step.
