Classification under different circumstances, Welding Wires, there are three classifications: electrode purpose classification, the main chemical ingredient of the drug skin classification drug skin melted slag characteristics.
Electrode uses two forms of expression, for the preparation of the former Ministry of Machinery Industry, can be divided into: structural steel welding rod, heat-resistant steel electrode, stainless steel electrode, welding electrodes, low temperature steel electrodes, cast iron welding rod welding rod nickel and nickel alloy rod, copper and copper alloys, aluminum and aluminum alloys and special purpose welding rod. Second is the national standard for carbon steel electrode, low alloy electrode, stainless steel electrode, Aluminium Welding Wires, cast iron welding rod, copper and copper alloys, aluminum and aluminum alloys. There is no difference in principle between the two, the former commercial grade, the latter with a Model.
Classified according to the chemical composition of the electrode coating, welding electrodes can be divided into: titania type electrode, titanium calcium type electrode the ilmenite type electrode, iron oxide-type electrode, cellulose-type electrode, low hydrogen type electrode graphite electrode and the base electrode.
Classification of many ways of welding electrodes, respectively uses slag basicity, the main component of the electrode coating, welding rod, the performance characteristics of different angles on welding electrodes are classified. By use classification
China's current the electrode classification method, welding materials prepared in accordance with the the electrode national standards and the former Ministry of Machinery Industry product samples. Electrode models are divided into eight categories according to national standards, and the electrode grade use is divided into 10 categories.Classification of welding electrodes
