Personally feel rod and wire are two entirely different concepts, does not need to do anything special distinction, welding rod coating and welding is composed of a core, the core is a solid core welding metal rod as electrode welding, conduction welding current, between it and the weldment arcing, and itself filled with metal. Medicated skin protection from the welding process, metallurgical processing, improved welding performance. Mainly for manual arc welding.
The wire is mainly used for MIG / MAG, TIG and other welding methods. (Ie SAW / MIG welding, electroslag welding, gas welding and other major welding materials used). Cored and solid wires into wire, its main function is simultaneously used to conducting filler metal or welding current. Also, sometimes the transition alloying elements to the weld through the wire, cored wire for self-protection in the welding process also protect, deoxygenation and to nitrogen and so on. Automatic welding wire is conducive to improve production automation. Specification welding. SMAW welder relies operating level. However, if done manually, using welding wire production efficiency is higher than with good weldability.
