Drug skin types: are not already required the type of power supply types: does not require the main features: zirconia, rutile and alkaline type in some of the electrode, these new slag system has not yet formed a series of drug skin types: titanium dioxide power Type: DC or AC main features: contain large amounts of titanium dioxide electrode process performance, stable arc, then arc, spatter is small, the penetration shallow, slag coverage, easy slag detachability, particularly appearance of the weld ripple can be all-position welding, especially appropriate for sheet metal welding, weld plastic and less crack resistance. With drug skin changes in the amount of potassium, sodium and iron, divided into high titanium potassium type, high-titanium sodium and iron titanium. Drug skin type: titanium calcium type of power: DC or AC main features: drug containing titanium dioxide in the skin for more than 30%, 20% calcium, magnesium carbonate, the electrode process performance, slag fluidity, and general penetration, arc stability, weld appearance, easy slag detachability, suitable for all position welding , such as the J422 is guilty of this type, is the currently the most widely used carbon steel electrode welding rod. Drug skin type: ilmenite type of power: DC or AC main features: drug skin containing ilmenite 305, electrode melting fast, good slag fluidity, penetration deep, easy slag detachability, solder wave neat. stable arc, welding wire , fillet welding process performance is better, lesser vertical welding weld has good crack resistance. drug skin types: iron oxide type of power: DC or AC main features: drug skin contain large amounts of oxidation iron and more ferromanganese Deoxidizer of, penetration, melting fast, high welding productivity, stable arc, then arc welding of overhead position welding is more difficult, splashing slightly larger weld thermal cracking performance than good for plate welding. Arc force, suitable for field operation. Drug skin by adding a certain amount of iron is iron titanium oxide type drug skin types: cellulose types of power supply: DC or AC main features: drug skin containing more than 15 percent organic matter, about 30% of the oxidation titanium, good welding performance, stable arc, Arc force, penetration, slag, slag detachability. Can be used for vertical down welding, forming welding deep penetration or one-side welding. Li, Yang welding consumable. Applicable to the welding of the sheet structure, fuel tank, pipeline, vehicle shell. Arc stabilization agent with the drug skin content of the binder, divided into high-cellulose sodium (DCRP), two types of high cellulose potassium.
