Electrode assembly with extension for submerged arc welding

Abstract

The disclosed technology relates generally to welding technology, and more particularly to electrode assemblies for arc welding, such as submerged arc welding. In one aspect, an electrode assembly for submerged arc welding (SAW) has a head portion and an extension portion arranged successively for feeding a consumable electrode therethrough, such that the head portion is disposed distal to an arcing tip of the consumable electrode during SAW and the extension portion is disposed proximal to the arcing tip of the consumable electrode. The head portion includes a contact tip configured to electrically contact the consumable electrode to supply power to the consumable electrode. The extension portion is formed from a single piece of insulating article configured for the consumable electrode to eventually pass through before the arcing tip is exposed.
