Development of filler metals for welding of iron aluminide alloys. Final report
- Lockheed Martin Energy Systems, Inc., Oak Ridge, TN (United States)
- Devasco International, Inc., Houston, TX (United States)
Attempts were made to develop a coating formulation for shielded metal arc (SMA) welding electrodes for iron aluminide alloys. Core wires of various compositions were produced by aspiration casting at ORNL and coating formulation development was conducted by Devasco, Inc. It was found that, except for weld deposit compositions containing less than 10 weight % aluminum, all weld deposits exhibited extensive cold cracking and/or porosity. It was concluded that current coating formulation technology limits successful iron aluminide deposits to less than 10 weight % aluminum.
