Electron beam melting is used to make larger ingots: an evacuated chaer is used under a vacuum in excess of 10 −4 Torr, with the metal held in water-cooled copper alloy moulds as for arc melting. As with the latter technique, several melting sequences are required with the ingot being turned over several times to ensure complete and even melting.
