The choice of electrode welded structures shall ensure safe and feasible use of the premise, according to the material to be welded chemical composition, mechanical properties, thickness and joint type, welding structural characteristics of the stress state, structural conditions of use of the weld performance requirements , welding construction conditions and technical and economic benefits such as integrated test, the electrodes used in a targeted manner and, if required for the welding test.

For alloy structural steel, alloy composition may also require the same or close to the base material. In welded structures rigid, high stress joints, weld cracks easily under unfavorable conditions, you should consider using a low strength than the base metal electrode. When the base material of carbon, sulfur, phosphorus and other elements of content is too high, the weld prone to cracking, good crack resistance should be used in alkaline low hydrogen type electrode. ② consider welded components and working conditions on the use of performance under load and shock load weldments, in addition to meet the strength requirements, should primarily ensure that the weld metal has a high impact toughness and ductility, the choice of plastic, high toughness index lower hydrogen type electrode. Contact with corrosive media weldment should be based on the nature of the medium class and corrosion characteristics of electrodes made of stainless steel or other corrosion-resistant electrode. High temperature, low temperature, abrasion, or other work under special conditions weldment should use the appropriate heat-resistant steel, low temperature steel, welding electrodes or other special purposes.

On uneven force, welding parts difficult to clean weldments should be used for rust, scale, oil-insensitive acid electrode. Conditions imposed can not flip on weldments should be used for all-position welding electrode. ④ considering construction conditions and economic performance of the product to meet the requirements of the situation, should be used with good acid electrode process. In small or poorly ventilated places, should be used or a low dust acid electrode welding. The structure of the welding workload, conditions should maximize the use of high-efficiency electrode, such as iron powder electrode, high efficiency gravity welding, etc., or use the underlying vertical down welding electrodes like the special electrode to improve welding productivity. (2) dissimilar steel welding electrodes choice points Ni102 nickel-based electrode, Ni112 nickel-based electrode, Ni202 nickel-based electrode, Ni207 nickel-based electrode, Ni307 nickel-based electrode, Ni307A nickel-based electrode, Ni307B nickel-based electrode, Ni317Ni327Ni337Ni347Ni357 ① different intensity levels + low alloy carbon steel (or low alloy steel + high strength low alloy steel) generally require the strength of the weld metal or joints of not less than two kinds of metal being welded minimum strength, the choice of the strength of the deposited metal electrode should guarantee weld and joint strength of not less than the strength of the base metal strength of the lower guillotine, while the weld metal toughness, ductility and impact strength should not be higher than the base material and the plastic guillotine poor performance. Therefore, according to both a lower intensity level among the selection of steel rod. However, in order to prevent weld cracking, should be a higher level of intensity, poor welding steels determine welding processes, including welding specifications, preheating temperature and post weld heat treatment. ② low alloy + austenitic stainless steel should follow on chemical composition of deposited metal values ??to a limited selection of electrodes, generally used in high chromium and nickel content, good ductility and crack resistance type austenitic steel Cr25-Ni13 welding, to avoid brittle cracks resulting hardened tissue. But poor weldability shall determine the welding of stainless steel and specifications. ③ stainless steel sheet should be considered for primary, complex layer, transition layer welding requirements choice of three different performance electrode. The grassroots (carbon steel or low alloy steel), welding, choose the appropriate intensity level structural steel electrode; stratified direct contact with corrosive media, should choose the appropriate ingredients austenitic stainless steel electrode. The key is the buffer layer (i.e. the interface with the primary multi-layer) welding, must consider the dilution of the base material, should be used with higher levels of chromium and nickel, good ductility and crack resistance Cr25-Ni13 austenitic steel electrode.
