<p>Sheets of thoria dispersed nickel are joined by a filler material consisting of a solid solution hardened alloy using inert gas arc welding techniques. The filler material is sized to provide the desired weld bead configuration and to maintain a sufficient separation between the sheet edges during joining to allow continuous welds of indefinite length; additionally the filler material is compatible with subsequent thermal processing of the sheets during the application of a chromium outer coating. The final coated assemblies have strong welds, free of porosity, and agglomeration of thoria is also avoided.</p> |
