Model of the Aluminum Electrodeis determined by the relevant national standards with international standards. EXXX, structural steel, for example, model preparation method for the letter "E", said electrode, said deposited metal minimum tensile strength, in the first two of the third digit electrode welding position, and the third, the four-digit type of welding current and the type of drug skin. GMT-ZT20 cast iron electrode stamping die cast iron module, commonly used models weld up the solder layer of martensite and excellent abrasion resistance. GMT-ZT30 cast Welding Rods used in gray cast iron, ductile iron welding repair, good machining performance. Intensity is twice that of the ordinary electrode. GMT-ZT40 cast iron electrode stamping die cast iron module welding repair, welding layer is martensite, excellent wear resistance. GMT-ZT50 cast iron electrode is mainly used for rendering the buffer layer. Nickel Welding Rod of high strength GMT-ZT60 cast iron electrode, mainly used for hard surface cover production base buffer layer. GMT-ZT65 cast iron welding rod for cast iron, alloy cast iron, steel and cast iron welding
(4) electrode models representation
Cast iron electrode with Z at the beginning, low temperature steel, nickel alloy electrode W Ni, heat-resistant steel welding rod, welding electrodes R with D chromium stainless steel electrode with GA, special welding rod, said silver-based electrode using the TS HL , copper and copper alloys T, aluminum and aluminum alloys with the L and air electrode with HS.

Welding under different circumstances, three classification methods: Classification of Welding Rods 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 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 Electrode, 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 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. The classification of the welding rod, respectively, by end-use, the different perspectives of the slag basicity, the main component of the electrode drug skin, the electrode performance characteristics to classify the welding. Use classification of the current electrode classification, is prepared according to the the electrode national standards and the Ministry of Machinery Industry of the welding material samples. The electrode model is divided into eight categories, according to national standards electrode grade use is divided into 10 categories.
