A method of fabricating an electric generator main lead bushing is provided for attaching a flange to a hollow conductor. In one application typically used for an air side flange, a gap is formed in the flange that is sized to receive an end of the conductor, a groove is formed in the conductor end, a braze alloy insert is placed into the groove, the conductor end is inserted into the gap, and the flange and the conductor are heated and cooled to provide a seal between the flange and the conductor. In another application typically used for a gas side flange, a counterbore is formed in an inner portion of the hollow conductor that is sized to receive the flange, a groove is formed in the counterbore, a braze alloy insert is placed into the groove, the flange is fitted into the counterbore, and the flange and the conductor are heated and cooled to provide a seal between the flange and the conductor.

[ What is claimed is:] [1.] A method of fabricating an electric generator main lead bushing, the method comprising the steps of:providing a hollow conductor having an end, said conductor end comprising a base and an inner portion;providing a flange;forming a gap having a bottom in said flange, said gap sized to receive said conductor end;forming a groove in said conductor end;placing a braze alloy insert into said groove;inserting said conductor end into said gap;heating said flange and said conductor so that the braze alloy melts and flows within said gap between said flange and said conductor; andcooling said flange and said conductor to solidify said braze alloy, thereby providing a seal between said flange and said conductor.
