Welding under different circumstances, three classification methods: Classification of welding rod use classification, according to the classification of the main chemical ingredient of the drug skin, drug skin melting slag characteristics.
There are two forms of expression in accordance with the purpose of the Welding Electrode, a former Ministry of Machinery Industry prepared, welding can be divided into: structural steel electrode, heat-resisting steel electrodes, stainless steel welding rod, welding electrodes, low temperature steel electrodes, cast iron electrode , nickel and nickel alloy rods, copper and copper alloys, aluminum and aluminum alloys and special purpose welding rod. National standards for carbon steel electrode, low alloy electrodes, stainless steel welding rod, welding electrodes, cast iron welding rod, copper and copper alloys, aluminum and aluminum alloys. Two there is no difference of principle, the former commercial grade, the latter model, said.
Classified according to the chemical composition of the electrode drug skin, welding can be divided into: type electrode of titanium dioxide, titanium dioxide calcium electrode, ilmenite type electrode, the iron oxide type electrode, cellulose type electrode, low hydrogen type electrode graphite electrode and the base Nickel Electrode.
According to the melting of the electrode drug skin characteristics of the slag to classification, welding can be divided into acid electrode and alkaline welding rod. The main ingredient of the drug skin acid electrode for acidic oxides such as silica, titanium dioxide, ferric oxide, etc.. Alkaline electrode main ingredient of the drug skin as alkaline oxides, such as marble, fluorite, etc.

According to the nature of the electrode drug skin, the electrode can be divided into two categories of acid electrode and alkaline welding rod. Drug skin contains large amounts of acidic oxides (TiO2, SiO2, etc.) electrode is called the acid electrode. Drug skin contains large amounts of alkaline oxides (CaO, Na2O, etc.) is called the alkaline electrode. Acid electrode AC and DC welding performance is good, but the weld mechanical properties, especially the poor impact toughness, suitable for low-carbon steel and low strength low alloy steel welding is the most wide electrodes. Alkaline electrode desulfurization, dephosphorization ability dehydrogenase role of drug skin. Welded joints hydrogen content is very low, it is also known as low-hydrogen electrodes. Alkaline electrode welds with good crack resistance and mechanical properties, but poor process performance, general welding with DC power supply is mainly used for welding of important structures (such as boilers, pressure vessels and alloy structural steel, etc.). According to the use of welding rod, welding rod can be divided into structural steel electrode (carbon steel electrodes and low-alloy welding rod), stainless steel electrodes, cast iron welding, heat-resistant steel Welding Electrodes, low temperature Welding Cable, welding electrodes, copper and copper alloys, nickel and nickel alloys, aluminum and aluminum alloys, including structural steel electrode is the most widely used.
