ABSTRACT:
An arc welding apparatus and method is described which includes a guide nozzle surrounding a non-consumable electrode and a shielding nozzle disposed outside the guide nozzle so as to feed a protecting inert gas about the electrode from a position within the guide nozzle and to feed a shielding carbon dioxide gas or a mixture of carbon dioxide gas and oxygen or other inert gas from a position within the shielding nozzle, whereby the electrode is protected by means of the guide nozzle and the protecting gas supplied therethrough and the outer portion of the arc is cooled to restrict the radial extent thereof by the shielding gas, while a deoxidizing reaction with the melted metal may be performed by means of the carbon dioxide gas and a deoxidizing agent within a welding rod when the latter is employed between the electrode and a base metal, or in the vicinity of the welding arc.
