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.

摘要： Disclosed is a method for affixing a metal cladding (3) to a metal base (2). The method includes: heating the metal cladding (3) and a surface of the metal base (2) with a heating device (11) to create a molten metal pool (20) having molten metal cladding layered upon molten metal base material in the metal base (2); stabilizing a temperature gradient of the molten metal pool (20) with a laser beam directed into the molten metal pool (20); and cooling the molten metal pool (20) to affix solidified cladding to the metal base (2).

摘要： An electrospark deposition electrode (20) and an associated method for depositing coatings using the electrode are provided. The electrode includes a powder of a first metal (36) and a powder of a second metal (38). The second metal (38) is a braze alloy including nickel, the second metal (38) having a lower melting point than the first metal (36). The powder of the first metal (36) and the powder of the second metal (38) are sintered together to form the electrode (20) so that the powders are comingled but not combined within the electrode (20). The method includes depositing a layer of the first metal (36) onto the substrate using an electrospark deposition process.
