摘要： A bimetallic ring (80) for use as a turbine shroud in a gas turbine engine. The bimetallic ring forms a sealing surface as a hot gas flow path boundary in the engine. The ring is comprised of two materials (82,84). The first material (82), a wrought, oxidation resistant metal alloy comprises a first portion, which is the hot gas flow path sealing surface. The second material (84), a low cost low alloy steel, comprises a second portion that may be at least a pair of supporting side plates. A dissimilar weld joint (86) joins the sealing surface to the second portion, the at least pair of supporting side plates.

摘要： A system and method for laser beam welding at least two adjacent superalloy components (102,104) involves substantially simultaneous formation of a base weld (110) with a first filler metal (106) placed between the components (102,104) and cap weld (112) with second filler metal (504) formed over the base weld. A shim (106) is inserted between the components (102,104), which may optionally be formed with a groove (105) along the joint surface (114). A filler wire (504) is fed to a location over the given surface (114) or within the optional groove (105). Two lasers or a laser and coupled beam splitter supply first and second laser beams (508,510) that are applied at focal points (512,514) separated by a predetermined distance (509), e.g., 0.05-1.5 cm. The first laser beam (508) is used to form a base weld (110) with the first filler metal (106) between the components (102,104), and the second laser beam (510) is used to form a cap weld (112) with the second filler metal (504) on top of the base weld (110).

摘要： A method of welding alloys having a ductility drop temperature range to limit strainage 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.
