| Abstract Scope |
The locomotive is being overhauled by forces of the Tennessee Valley Railroad Museum to serve as the flagship of Norfolk Southern’s new public relations effort “21st Century Steam.” This overhaul includes a complete investigation of the boiler and the performance of repairs to ensure compliance with the ASME boiler code and Federal Railroad Authority regulatory requirements. The locomotive was built in 1911 by the Baldwin Locomotive Works. The fire tube boiler is of riveted construction. The material in the boiler is carbon steel but predates ASTM standards. This paper presents the investigation of a forge welded joint from the boiler. In addition to characterization of the material composition and mechanical properties, the microstructure of the 100 year old base material and joint was examined with optical and electron microscopy. |
