Electrode assembly having an extension with insulating sleeve and non-magnetic envelope for submerged arc welding - Patents.com

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 has a contact tip portion and an extension portion arranged contiguously therethrough and configured to feed a consumable electrode therethrough. During welding, the contact tip portion is disposed distal to the arcing tip of the consumable electrode, and the extension portion is disposed proximal to the arcing tip of the consumable electrode. The extension portion is configured to electrically insulate the consumable electrode from a workpiece during welding, with a solid insulating material surrounding the consumable electrode.
