摘要： A turbine bucket that includes a pressure side, a suction side opposite the pressure side, and a rib extending between the pressure side and the suction side. A tip cap is attached to the pressure side and the suction side and covers the rib. The tip cap includes a precipitation hardened material and a passage aligned with the rib. A method for assembling a turbine bucket having a pressure side and a suction side and a rib extending between the pressure side and suction side. The method includes receiving a tip cap made from a precipitation hardened material and having a passage in the tip cap. The method further includes locating the rib visually through the passage and aligning the passage with the rib. The method also includes welding the tip cap to the turbine bucket and to the rib.

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.
