Abstract: A crack-resistant member for preventing crack propagation, a method of preventing crack propagation, and method of assembly a tower are provided. The crack-resistant member includes at least one insert attached to at least one removed portion at a predetermined location along a girth weld and adjacent a heat affected zone of the tower. The at least one insert is positioned perpendicular to a weld direction and intersecting the girth weld. The at least one insert prevents crack propagation in the girth weld of the tower.

Abstract: A brazing process, a braze arrangement, and a brazed article are disclosed. The brazing process includes brazing an article with a braze arrangement. The braze arrangement includes a first braze material and a second braze material, the first braze material having a first melting point and the second braze material having a second melting point, the first melting point differing from the second melting point. The brazed article includes a treatment region, a first brazed material positioned within the treatment region, and a second brazed material positioned distal from the article in comparison to the first brazed material. The first brazed material is formed by the first braze material and the second brazed material is formed by the second braze material.

Abstract: A bimetallic ring 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. The first material, a wrought, oxidation resistant metal alloy comprises a first portion, which is the hot gas flow path sealing surface. The second material, 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 joins the sealing surface to the second portion, the at least pair of supporting side plates.
