The Nickel Alloy project is working to continue development of research to increase the
weldability of nickel-chromium alloys. Our approach is to control oxidation sources within the
process through atmospheric controls and monitoring. To accomplish this, the team has
constructed an Atmospheric Control Chamber to enable control over both the ambient atmosphere and
the local shielding gas. In addition, an oxygen detector is being implemented to allow precise
measurements of the atmospheric oxygen content.
By varying the weld parameters, as well as experimenting with various shielding gas
configurations, we are exploring how various parametric changes affect the quality of the
