Twin-wire GMAW was demonstrated to show significant potential over conventional single-wire GMAW with a modest increase in cost. Large-scale fabricators should compare advanced two-wire GMAW systems to maximize productivity and business case of welding applications.

R GAS METAL ARC WELDING Designed to revolutionize heavy fabrication productivity, the HyperFill® twin wire MIG solution allows for increased deposition rates without compromising puddle st.

May 1, 2012 · Compared with GMAW twin wire welding, a refined micro-structure in the weld and heat-affected zone (HAZ), narrow HAZ and improved joint strength were achieved with TANDEM on Q690.

Fortunately, advancements in twin-wire welding – specifically the patented Lincoln Electric HyperFill® twin-wire process – have made it possible to achieve higher levels of productivity while eliminating or reducing the impact of these common challenges. Learn how a new twin-wire GMAW process can increase productivity from 25-85%

Mar 25, 2019 · Lincoln Electric® introduces HyperFill™, a patent pending twin-wire GMAW welding solution that revolutionizes high deposition welding. Due to its innovative twin-wire design, HyperFill is able to utilize two smaller diameter wires to produce a …

May 7, 2019 · Lincoln Electric’s HyperFill, a patent-pending twin-wire gas metal arc welding (GMAW) product developed for semi-automatic or robotic applications, increases the usable deposition rate as compared to traditional single-wire GMAW while delivering improved weld quality and puddle stability, according to company officials.

Oct 29, 2020 · Twin-wire gas metal arc welding (TW-GMAW) was recently evaluated for use in high-productivity precision fillet welding applications by EWI. The results show that TW-GMAW offers deep penetration, a wide and smooth underbead profile, omni-directional deposition, process stability with variations in CTWD, lower cost setup, and high-deposition arc ...

Jan 11, 2023 · The triple-arc (Tri-Arc) twin-wire gas metal arc welding (GMAW) is a novel twin-wire welding method, compared with the conventional twin-wire GMAW process; it decouples heat input and deposition rate by creating an inter-electrode arc between the two wire ends, called the middle-arc (M-arc).

In the tandem MIG/MAG process (sometimes referred to as 'twin-wire' or double wire welding), two wires are continuously fed through a special welding torch and are consumed to form a single molten pool.

Although more complicated than regular GMAW, twin-wire gas metal arc welding offers benefits that include high deposition rates and increased travel speeds.
