DEFINITION

Classification: 164/469

Utilizing electric arc or electron beam melting:

(under subclass 459) Process including raising the temperature of work material to its molten state through either (a) electric arc discharge between an electrode and the work material, or (b) electron beam bombardment upon the work material.

(1) Note. Included herein is the use of two electrically charged metal rods adapted to form an electric arc wherein both are melted to supply casting material and also the use of a single charged rod in a consumable electrode of suitable material.
