Twin-Wire GMAW Ups Productivity in High-Deposition Welding
June 25, 2019Comments
Lincoln Electric’s HyperFill, a patent-pending twin-wire gas metal arc welding (GMAW) product developed for semi-automatic and 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.
With its twin-wire design, HyperFill can utilize two smaller-diameter wires to produce a larger weld droplet and arc cone. In return, this generates a large weld puddle that is easier to manage and control, reportedly allowing operators on average to increase usable deposition rates to 50 percent as compared to traditional single-wire processes.
And, unlike traditional twin-wire processes, which typically require dual power sources or dual contact tips, HyperFill uses a single power source, feeder, gun liner and contact tip. This allows operations to improve weld deposition without complex system setup.
