  • Weld Repair Method for a Turbine Bucket Tip
    Publication number: 20090014421
    Abstract: A weld repair method uses a gas tungsten or plasma arc welding torch and matching filler. An amperage supplied to the torch and a travel speed of the torch are controlled to produce a weld bead having a mushroom shape. The weld bead is ground from all sides to remove at least one half of a thickness of the weld bead, and another weld bead is formed. The technique produces crack free welds with directionally solidified weld metal that is similar to that of the base material and hence has comparable mechanical properties.
