![]() ![]() While gas metal arc welding (GMAW) using a solid mild steel wire is commonly used and effective, it does have limitations. They offer improved speed and efficiency in these scenarios. □□įlux cored wires excel in various welding applications, such as vertical-up welding, flat welding, welding over galvanized materials, and tackling hard-to-weld steels. Why settle for a solid wire when you can achieve superior results with a flux cored wire? Flux cored wires are specifically designed to deliver performance that surpasses what can be achieved with solid wires. ⚡□ Advantages of Flux Cored Welding Wire: Better Performance, Faster Results! □□ We are working hard at putting these on our website, so if you cannot see the product here yet, or just need technical support, call us free on 080. ![]() Good welding practice dictates that the base metal should be cleaned of contamination prior to welding but, if this is not possible, these wires are the preferred choice.AES stock a vast range of fluxed cored and metal cored welding wires, available in gas shielded and gasless varieties. They are typically greater than 1/16” diameter and are primarily applied for high deposition welding on thicker base materials (>1/4”) This family of wires offers a greater resistance to base metal contamination, and they have been shown to perform well over some rust and mill scale. A common problem from incorrect gas selection is weld cracking.įlat-position wires (E-70) can be utilized in the flat or horizontal welding positions. Failure to do so may result in poor quality welds. In all instances, the shielding gas selected should be matched with the recommendation of the filler metal manufacturer. Shielding gas selection can be pure CO2 or C25. They are not well suited for use where high levels of base metal contamination exist, but offer good control when welding in the vertical up or over-head position. With the proper selection of wire type and shielding gas, weld properties are excellent for many types of materials.Īll-position wires (E-71T-1) are typically smaller than 1/16” in diameter and are formulated with a fast-freeze flux. Flux-cored wire welding is especially useful where the base material to be welded has some amount of scale, rust or other surface contaminants present. ![]() Gas-shielded flux-cored wires are used in operations such as shop fabrication, maintenance, and shipbuilding. Among the most common are outdoor construction and fabrication in areas where gas cylinders and gas shielding cannot be readily used. Generally, self-shielded wires are used for welding outside or for special applications such as welding galvanized steel. The type of Flux Cored Welding wire used depends on the welding position, the mechanical properties required, the type of joint and its fit-up, and the environment in which the welding is to be performed. There are three types of flux-cored wires available: When compared with MIG welding, higher deposition rates are possible, especially when welding out of position. Flux Cored Welding combines the high productivity of MIG welding using a solid electrode with the ability to weld on more contaminated base material. The resulting weld bead is covered by a residual slag (melted and solidified flux) which helps to protect and shape the finished weld, and is generally easily removed upon completion of the weld. The flux-cored electrode is a composite tubular filler metal consisting of a metal sheath with a core of mineral compounds and powdered metals. Flux-Cored Arc Welding (FCAW) utilizes a continuously-fed tubular electrode, electrical power to melt the electrode, and may or may not use shielding gas from an externally supplied source when depositing material in the weld joint. ![]()
