According to different circumstances, there are three kinds of welding electrodes classification: According to the use of electrode classification according to the main chemical composition of the coating, according to the characteristics of molten slag melting slag classification.
According to the use of the electrode, the 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 electrodes and special purpose electrodes.
If you follow the main chemical composition of the electrode coating to be classified, you can electrode is divided into: titanium oxide type electrode, calcium titanate type electrode, ilmenite type electrode, iron oxide type electrode, cellulose type electrode, low hydrogen type electrode , Graphite type electrode and salt type electrode.
If according to the electrode coating melting, the characteristics of slag to classify, the electrode can be divided into acidic and alkaline electrodes. Acidic electrode coating the main component of acidic oxides, such as silica, titanium dioxide, iron oxide and so on. Alkaline electrode coating of the main components of alkaline oxides, such as marble
