Electrode data general formula is: weld basal area * weld length * Steel proportion / consumption rate. It is worth mentioning that the consumption rate varies according to the Welding Rod in the form and structure, 50% ~ 60% of the ordinary welding, gas shielded arc 85%, submerged arc lower, while the welder operating at different levels of consumption ; Another should be noted that the weld-off area should be noted that the weld vector fillet weld vector part of the area is about 1.21 times the area of ??a triangle. For example, solder pin for 10MM Fillet weld length is 10M, then the Welding Electrode consumables dosage:= 0.010 * 0.01 / 2 * 1.21 * 7850 * 10/0.6 (loss) welding
Electrode classified according to different situations, welding, there are three classification methods: by welding rod use classification, according to the classification of the main chemical components of the drug skin, according to the slag after the melting of drug skin characteristics classification. In accordance with the purpose of the welding rod, welding can be divided into: structural steel welding rod, heat-resisting steel electrodes, stainless steel Welding Electrode , welding electrodes, low temperature steel electrodes, cast iron electrode, nickel and nickel alloy electrode, copper and copper alloys, aluminum and aluminum alloy electrode, and special purpose welding rod. 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.
