Durarc® Process for Melting and Casting Titanium

  • Albert R. Vaia
  • Ronald R. Akers


The utilization of an independent heat source, such as a nonconsumable electrode, for process and product improvem nt is gaining acceptance throughout the industry and the Durarc® electrodes have shown the capacity to operate in a variety of these applications. Based on results obtained in both production and research installations, nonconsumable melting has proven to be effective for many of the processes previously accomplished by: consumable electrode, plasma, electron beam and hollow cathodes.
