According to different circumstances, there are three kinds of welding electrode classification method: according to the use of electrode classification, according to the main chemical composition of the skin, according to the characteristics of the characteristics of slag after melting.
According to the purpose of the electrode, the welding electrode can be divided into: structural steel electrode, heat-resistant steel electrode, stainless steel electrode, surfacing electrode, low temperature steel electrode, cast iron electrode, nickel and nickel alloy electrode, copper and copper alloy electrode, aluminum and aluminum Alloy electrode and special purpose electrode.
If the main chemical composition according to the electrode coating classification, the electrode can be divided into: titanium oxide electrode, titanium oxide calcium electrode, ilmenite electrode, iron oxide electrode, cellulose type electrode, low hydrogen electrode , Graphite electrode and salt-based electrode.
If the filter in accordance with the electrode after melting, the characteristics of slag to classify the electrode can be divided into acidic and alkaline welding electrodes. Acid electrode coating of the main components of acid oxides, such as silica, titanium dioxide, ferric oxide and so on. Alkaline electrode coating of the main components of alkaline oxides, such as marble, fluorite and so on.
