To get the most out of gas-shielded flux cored arc welding, it is useful to select a welding power source that can keep up with the productivity the process and filler metal can provide. a welding gun (complete with a nozzle mounted to a diffuser) to deliver both wire and gas from the wire feeder to the weld.a hose to deliver gas from the flowmeter to the wire feeder.a flowmeter which mounts to the tank to supply the appropriate flow of shielding gas.In addition to the shielding gas itself, FCAW-G also requires the following equipment: Different shielding gasses can be used to achieve benefits such as additional penetration or a smoother arc with reduced spatter. Always double check the filler metal’s data sheet efore welding to ensure that the shielding gas being used is of the appropriate composition for the wire being used. Typically, the shielding gas cylinders used for FCAW-G are filled with either 100% carbon dioxide or argon/carbon dioxide mixtures. Shielding gas cylinders are bulky and the external shielding gas plume must be protected from breezes, but FCAW-G has many benefits in the production environment ranging from aesthetic welds to hard-to-beat deposition rates-sometimes even out of position. Gas-Shielded Flux Cored Arc Welding (FCAW-G)Īs the name implies, FCAW-G requires the use of an external shielding gas contained in a cylinder to prevent porous welds. To maximize productivity and quality, welders should become familiar with the welding tools and equipment of both processes so that they can quickly setup and operate whichever process is best for their application and welding environment. FCAW-G is most often used indoors, while FCAW-S is typically used outdoors.

Unlike shielded metal arc welding, flux cored welding can be divided into two distinct processes: self-shielded flux-cored arc welding (FCAW-S) and gas-shielded flux-cored arc welding (FCAW-G).īoth the home hobbyist and professional welder will encounter situations where one process is advisable over the other. Like shielded metal arc welding (SMAW, stick), Flux Core Welding (FCAW) is a popular welding process that uses the assistance of flux within a tubular wire to help produce high-quality welds.
