Solid Wire is a consumable electrode made of metal used for welding metals in the electric arc welding process. Unlike flux-cored wires, solid wires have a solid metal core that provides filler material to join the workpieces. The wire is melted in the arc and fused with the base metal to form a solid, homogeneous joint. Solid wires are commonly used in various welding applications including manual metal arc welding, gas metal arc welding, and gas tungsten arc welding. They are available in various materials, diameters, and coatings to suit different welding requirements.
