Abstract: A method for forming an article is disclosed, including laser welding a powder of an HTW alloy to a surface of a substrate along a weld path, forming a weld bead of the HTW alloy. The weld path is propagated along a weld direction, forming a cladding layer of the HTW alloy on the surface. The laser welding includes a laser energy density of at least about 11 kJ/cm2, and laser welding the powder to the surface includes a welding speed of about 5-20 ipm. The weld path oscillates essentially nonparallel to a reference line, establishing a cladding width wider than the weld bead width. The weld bead contacts itself along each oscillation such that the cladding layer is continuous and essentially free of cracks. A turbine bucket is disclosed including a squealer tip having the cladding layer with a cladding layer thickness of at least about 0.2 inches.

Abstract: Method of forming or repairing a part with an overhung section. The method may include removing a portion, and adding a section to the part. The section includes the overhung section. The adding includes sequentially layering at least one plurality of material layers on the part, the at least one plurality of material layers approximating dimensions of the section including the overhung section. The sequential layering may include, for example, laser welding, and may be carried out in a number of ways that create varied layers within the overhung section. The method may include machining the at least one plurality of material layers to form the section including the overhung section.
