7 indicates tensile strength (here, 70,000 pounds per square inch ).Note that hardsurfacing wires do not have a classification according to the American Welding Society (AWS), but all other gas- and self-shielded flux-cored wires do.Īs an example, a gas-shielded flux-cored wire designed for welding mild steel has the AWS classification E70T-1C. Flux-cored wires also are available for hardsurfacing new parts to protect them from impact and abrasion and for rebuilding old or worn-out parts. Gas-shielded and self-shielded flux-cored wires are available for flat/horizontal or all-position welding on base materials ranging from mild and low-alloy steel to stainless steel and special alloyed metals like chrome-moly. Common applications for gas-shielded flux-cored wires include general fabrication, pressure vessels, petrochemical piping, and heavy-equipment manufacturing.

The flux in self-shielded wires generates the shielding gas, which makes these wires highly portable and ideal for outdoor welding applications, such as structural steel, shipbuilding, and bridge construction. Both types are composed of an outer sheath and are filled with flux, a compound that is a mixture of alloys and deoxidizers, the latter of which are necessary to protect the weld from contaminants.Īs their name implies, gas-shielded flux-cored wires require an external shielding gas supply to protect the weld self-shielded wires do not. With more knowledge you can choose and use flux-cored wires confidently for your own welding applications.įlux-cored wires have been around since the 1950s and are available in two main versions: gas-shielded and self-shielded. Becoming acquainted with some basics, including the most appropriate applications, general classifications and characteristics, and advantages and limitations, of flux-cored wires can yield significant results. The Welders Supply Company sells all the materials you will need to maintain and perfect your weld.By arming yourself with some basic knowledge, you can choose and use flux-cored wires for your own welding applications confidently.įlux-cored arc welding (FCAW) wires certainly aren't new, but like any part of the welding process, understanding them can be confusing-without the right information. The sheer ability to use these machines outside on almost all materials makes them an invaluable machine to have in any workshop and/or jobsite. This byproduct covers and further helps to reinforce the weld making the end result very unsightly if the excess is not chipped away. Air causes a weld to become weak if this welding pool is not protected from said environment, and with Flux Cored wire this pool is protected by the vapor and a residue from the weld called slag. With the addition of Flux Cored wire which is wire that has been hallowed out and filled with a powered Flux material and activated when coming into contact with the arc releasing a vapor that shields the welding pool of molten metal from the environment.
This is no longer the case with the latest innovation in welding, particularly MIG welding.
EAGLE ARC FLUX CORED WIRE PROFESSIONAL
Welders from professional to hobbyist have been restrained from welding dirty and/or rusty materials, and from performing outside.
