Welding electrode is composed of covering and core, the core is a solid metal bar, the cover plays a role of protection, improved the welding performance. The welding electrode is mainly used for manual arc welding, production efficiency and welding performance is better than welding wire.
The welding wire is mainly used for MIG/MAG, TIG welding method, etc. Welding wire is divided into flux cored wire and solid wire. Welding wire is beneficial to realize automatic welding, improve automation production.
