  • Welding of Reactive and Refractory Metals

    2018-4-24 · Welding Refractory Metals It is obvious that these metals must be perfectly clean prior to welding and that they must be welded in such a manner that air does not come into contact with the heated material. Cleaning is usually done with chemicals. A water rinse is necessary to remove all traces of chemicals from the surface.
