ABSTRACT:
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.
