Document Type and Number:
Japanese Patent JP4933054
Kind Code:
B2
Abstract:
A process for repairing a compressor rear frame of a gas turbine engine. The process entails removing a seal flange (118) from the inner casing wall (12) of the frame (10) to define an annular face (130) on the casing wall (12), and fabricating a replacement flange (118) to have an annular face (132) with a radial width greater than the radial width of the annular face (130) of the casing wall (12). The faces (130,132) of the flange (118) and wall (12) are mated to form a joint (122), a penetration-enhancing flux (128) is deposited adjacent the joint (122), and a single-pass gas tungsten arc welding operation is performed to form a root weldment (124) that extends completely through the joint (122). The flux (128) is then removed and a gas tungsten arc welding operation is performed to deposit a filler on the root weldment (124) and form a second weldment that completely overlays but does not penetrate through the root weldment (124).
