摘要
A method of arc welding under superatmospheric pressure, characterized by the following combination of operations: providing a gaseous environment in a chamber around or around the workpiece or structure to be welded; depositing weld metal from a consumable flux core arc welding wire containing at least one strong deoxidizer (as defined in the description) and protecting an arc that jumps between the welding wire and the workpiece or structure to be welded by a gaseous mixture comprising at least one inert gas (as defined in the specification) and oxygen and/or a gas containing oxygen which, under the action of the arc, decomposes to release oxygen or reacts with the strong deoxidant (s).
