Abstract: In gas tungsten arc welding (GTAW), the achievable deposition rate of the filler wire is coupled with the arc energy and the mass of the molten metal in the weld pool. In this invention, a side arc is added into the GTA (gas tungsten arc) between the wire and the same tungsten that establishes the GTA with the work-piece. While its anode provides a GMAW (gas metal arc welding) melting mechanism to completely melt the wire at high speeds, the undesirable dependence of deposition rate on the weld pool mass is also eliminated. As a result, the deposition rate is increased and the ability to provide desirable deposition rate and base metal melting/penetration freely without coupling is established for the GTAW.
