摘要： A system and method for laser beam welding at least two adjacent superalloy components involves substantially simultaneous formation of a base weld with a first filler metal placed between the components and cap weld with second filler metal formed over the base weld. A shim is inserted between the components, which may optionally be formed with a groove along the joint surface. A filler wire is fed to a location over the given surface or within the optional groove. Two lasers or a laser and coupled beam splitter supply first and second laser beams that are applied at focal points separated by a predetermined distance (e.g., 0.05-1.5 cm). The first laser beam is used to form a base weld with the first filler metal between the components, and the second laser beam is used to form a cap weld with the second filler metal on top of the base weld.

摘要： 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.
