    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 method of welding alloys having a ductility drop temperature range to limit strain-age cracking. The method involves the use of a welding device to weld a weld area of an article while maintaining temperatures throughout the weld area and a heat affected zone adjacent the weld area within a non-crack sensitive temperature range that is above a ductility drop temperature range of the alloy being welded. During welding, the temperatures of the weld area and the heat affected zone are predominantly controlled with heat input from the welding device. Once the welding has been terminated, the weld area and the heat affected zone are cooled from the non-crack sensitive temperature range through the ductility drop temperature range to a temperature below the ductility drop temperature range of the alloy.

    摘要: A welding method and apparatus for welding workpieces together by conducting a forward hybrid welding process on a joint region that includes a weld seam defined by and between faying surfaces of the workpieces, and then conducting an aft hybrid welding process on the joint region. The forward hybrid welding process simultaneously causes a forward laser beam and a forward electric arc to travel along the joint region, which in combination penetrates the weld seam and forms a weld pool that solidifies to form a weldment. The aft hybrid welding process utilizes an aft electric arc and an aft laser beam to produce a second weld pool that remelts and mixes with the weldment. On cooling, a weld joint is formed that is capable of deeply penetrating the weld seam of the joint region.
