Flux-Cored Arc Welding Shielding Gas

In Flux-cored arc welding, shielding gas may be used as it generally produces welds of better and more consistent mechanical properties, with fewer weld defects than either the SMAW or GMAW processes. Shielding gas equipment for flux-cored arc welding consists of a gas supply hose, a gas regulator, control valves, and supply hose to the welding gun. … Read more

Flux Cored Arc Welding (FCAW)

Flux-cored arc welding or tubular electrode welding has evolved from the MIG welding process to improve arc action, metal transfer, weld metal properties, and weld appearance. It is an arc welding process in which the heat for welding is provided by an arc between a continuously fed tubular electrode wire and the workpiece. Shielding is obtained … Read more

Flux-Cored Arc Welding Advantages

The major advantages of flux-cored arc welding are reduced cost and higher deposition rates than either SMAW or solid wire GMAW. The cost is less for flux-cored electrodes because the alloying agents are in the flux, not in the steel filler wire as they are with solid electrodes. Flux-cored welding is ideal where bead appearance is important … Read more

Flux-Cored Arc Welding Principles

The flux-cored welding wire, or electrode, is a hollow tube filled with a mixture of deoxidizers, fluxing agents, metal powders, and ferro-alloys. The closure seam, which appears as a fine line, is the only visible difference between flux-cored wires and solid cold-drawn wire. Flux-cored electrode welding can be done in two ways: carbon dioxide gas … Read more

Flux-Cored Arc Welding Equipment

Flux-cored arc welding equipment is similar to the equipment used for gas metal arc welding. The basic arc welding equipment consists of a power source, controls, wire feeder, welding gun, and welding cables. A major difference between the gas shielded electrodes and the self-shielded electrodes is that the gas-shielded wires also require a gas shielding system. This … Read more
