according to different situations, welding, there are three classifications: Classification by use of electrode, by the skin of the main chemical ingredient drug classification of drugs according to the characteristics of the skin melted slag classification.

According to the use of welding, Carbon Steel Welding Electrode can be divided into: structural steel welding rod, heat-resistant steel electrode, stainless steel welding rod, welding electrodes, low temperature steel electrodes, cast iron welding rod, nickel and nickel alloy electrodes, copper and copper alloy rod, aluminum and aluminum alloys and special purpose welding rod.

If the drug under the skin electrodes to the classification of the main chemical components, welding can be divided into: titania type electrode, titanium calcium type electrode, ilmenite-type electrode, iron oxide-based electrodes, cellulose type electrode, low hydrogen type electrode , graphite electrode and the type of base electrode.

If the drug under the skin electrode melting, the slag characteristics to classify, welding can be divided into acidic and basic welding electrodes. Acidic drug electrode main component of skin acidic oxides such as silica, titanium dioxide, iron oxide and so on. Basic electrode for the main component of skin medicine alkaline oxides, such as marble, fluorite.

An electrode type according to the mechanical properties of deposited metal, drug skin type, welding position and welding current of each type of

Type 2 electrodes prepared as follows: the letter E, said electrodes; first two numbers indicate the minimum tensile strength of deposited metal; the third digit position of the welding electrode, said welding to 1 .0 and suitable for all position welding (flat, Li, Yang, Wang), "2" for flat welding electrodes and Welding Electrodes and flat, "4" stand down, said electrode for welding; third and fourth digit combinations, said welding current skin type and drug type. Added in the fourth digit after the "R" means resistance to moisture absorption electrode; additional "M" indicates resistance to moisture absorption and mechanical properties of the electrode with special requirements; additional "-1" indicates that the impact of special provisions of the electrode performance.
