  • Flux assisted gas tungsten arc welding utilizing consumable inserts for ultra low profile welding applications
    Patent number: 7285747
    Abstract: A speedy method of welding in a tight space using a single pass is provided using a technique which involves the use of a particularly shaped, flux treated consumable insert to provide deep weld penetration by a GTAW machine which is compact and fits the narrow spaces found in applications such as feeder tube repair since it does not require an insert wire flux feed system and is thus capable of negotiating narrow spaces found in feeder tubes.
