Electrodes are generally the drugs skin, wrapped in wire outside, often there are 1.5, 2.5,3.2,4,5,6 mm diameter. Used for manual arc welding. Welding Wires Manufacturer is usually no medicine out of the skin, or the medicine inside the skin wrapped in wire, a one, in addition to TIG welding and hand, but mostly for semi-automatic and automatic welding. The first two are with solid wire, solid wire which both have cored wire. After welding solid wires no drugs skin protection, welding electrodes and cored wire after drug skin protection. Electroslag welding and submerged arc welding the skin after the drugs, but drugs are pre-welded at the welding shop aisle, so they also use solid Flux Cored Welding Wires. Regardless of electrode or welding wire, welding should achieve the purpose.
