Twin wire

For twin-wire welding, two wires are connected to the same power source. A standard SAW machine is equipped with double drive rolls and contact tips suitable for feeding two wires simultaneously. It produces considerably higher deposition rates than the conventional single-wire process using large diameter wires.

It offers up to 30% higher deposition rates and can be used at higher currents and speeds. Very high welding speeds can be achieved in fillet welding, but are also used successfully for butt welding. Cored wires can further enhance deposition rates.
