Cored wires are a type of welding consumable that consists of a metal sheath surrounding a flux core. The flux core is made up of various powders and chemicals that provide shielding gas, deoxidizers, and other additives to improve the quality of the weld. Cored wires are used in a variety of welding applications, including gas metal arc welding (GMAW), flux-cored arc welding (FCAW), and submerged arc welding (SAW). They are available in a range of sizes and compositions to suit different welding processes and materials, such as carbon steel, stainless steel, and aluminum. Cored wires offer several advantages over solid wires, including higher deposition rates, better penetration, and improved weld quality. They are widely used in industries such as construction, automotive, and shipbuilding.
