(1) drug skin types: are not already requires the type of power supply types: does not require the main features: zirconia, rutile and alkaline type in some of the electrode, the new slag system has not yet formed a series of
(2) drug skin types: titanium dioxide supply types: DC or AC main features: containing large amounts of titanium dioxide electrode process performance, stable arc, then arc, spatter is small, the penetration shallow, slag coverage good, easy slag detachability, particularly appearance of the weld ripple can be all-position welding, especially appropriate for sheet metal welding, but weld ductility and crack resistance somewhat less. Divided into high titanium potassium type, high-titanium sodium and iron titanium with the amount of potassium, sodium, and iron and other drug skin
(3) drug skin types: titanium calcium type of power: DC or AC main features: drug skin containing 30% titanium dioxide, calcium, magnesium carbonate, 20%, the electrode process performance, slag fluidity. penetration in general, arc stability, weld appearance, easy slag detachability, suitable for all welding positions, such as the J422 is guilty of this type is the most widely used carbon steel electrode electrode.
(4) the type of drug skin: ilmenite type of power: DC or AC main features: drug skin containing ilmenite 305, electrode melting fast, slag fluidity, penetration deep, easy slag detachability, welding neat waves, stable arc welding, fillet welding process better performance, lesser vertical welding weld the crack resistance
(5) drug skin types: iron oxide type of power: DC or AC main features: drug skin with large amounts of iron oxide and more ferromanganese deoxidizer, deep 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 is better, apply to plate welding. Arc force, suitable for field operation. If drug skin by adding a certain amount of iron is iron titanium oxide type
(6) drug skin types: cellulose type of power: DC or AC main features: drug skin containing more than 15 percent organic matter, about 30% titanium dioxide, good welding performance, stable arc, Arc force, melting deep, slag, slag off. Can be used for vertical down welding, forming welding deep penetration or one-side welding. Li, Yang welding process. 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 kinds of high-cellulose potassium
(7) drug skin types: the type of power of the low hydrogen potassium type (low hydrogen sodium type): the main features of the DC or AC (DC): drug skin composition of carbonate and fluorite. Electrode before use subject to the 300 ~ 400 ℃ baking. Short arc welding process in general, all-position welding. The weld has good crack resistance and mechanical properties of force. Suitable for the welding of welded structures. In accordance with the dose of drug skin in the steady arc, the amount of iron and binder divided into low hydrogen sodium type, low hydrogen potassium type and iron powder low hydrogen type
(8) drug skin types: graphite type of power: DC or AC main features: drug skin containing large amounts of graphite, usually cast iron or hardfacing electrode. Low-carbonStainless Steel Welding Electrodescore, poor welding performance, splash more, smoke less slag suitable for flat welding. The use of non-ferrous metal welding core, they can improve their process performance, but the current is not easy too large
(9) drug skin types: base type of power: DC main features: drug skin contain large amounts of chloride and fluoride, is mainly used for aluminum and aluminum alloys. Moisture absorption, drying prior to welding. Drug leather low melting point, melting fast. DC power supply, welding process is poor, short arc, slag, corrosive, hot water cleaning is required afterWelding Rod
