(1) Pharmaceutical skin types: the type is not a type of power supply has been provided: does not require the main features: the use of electrodes in some zirconia, rutile alkaline-type, these new series has not yet formed slag
(2) drug skin types: titanium dioxide-based Power Supply: AC or DC main features: with large amounts of titanium dioxide, welding process with good performance, stable arc, easy arc again, splashing a small, shallow penetration, slag coverage good, easy slag removal, weld ripples special appearance, can be all-position Welding Wire, particularly appropriate sheet metal welding, but somewhat less weld ductility and crack resistance. With the skin in drug potassium, sodium and iron the amount of such changes, are divided into high-titanium potassium, high sodium and iron titanium and other titanium-based
(3) drug skin types: titanium calcium type Power Supply: AC or DC main features: leather medicine containing more than 30% titanium dioxide, calcium, magnesium carbonate 20%, welding process with good performance, slag fluidity, penetration in general, arc stability, weld appearance, easy slag removal, suitable for all position welding, such as the J422 guilty of this type, is the most widely used carbon steel electrode in an electrode.
(4) drug skin type: ilmenite-type Power Supply: AC or DC main features: leather medicine containing ilmenite 305, electrode melting fast, slag fluidity, deep penetration, easy slag removal, welding wave neat, stable arc-welding, fillet welding performance is better, a little sub-vertical welding, the weld has good crack resistance
(5) Pharmaceutical skin types: iron oxide-type Power Supply: AC or DC main features: skin contains large amounts of drugs more ferromanganese oxide and oxygen scavenger, deep penetration, melting fast, high productivity welding, arc stability , then arc convenient, Welding and Overhead welding more difficult, flying larger, better weld thermal cracking performance for plate welding. As the Arc force, suitable for field operation. If the drug in the skin by adding a certain amount of iron powder, iron powder titania type was
(6) drug skin types: cellulose-type Power Supply: AC or DC main features: leather medicine containing more than 15% organic matter, 30% of titanium dioxide, good welding performance, stable arc, Arc force, melting deep, less slag, slag off easy. Can be used for vertical down welding, deep penetration welding or forming side welding. Li, Yang-welding process is good. Sheet structure for the fuel tank pipe, casing and other vehicles, welding. Stable arc with the skin of drug agent, binder content changes, are divided into high cellulose type (DC reverse), two types of high cellulose potassium (7) drug skin types: low hydrogen potassium type (low-sodium hydrogen ) Power Supply: AC or DC (direct current) main features: drug ingredients to the skin carbonate and fluorite-based. Electrode prior to use shall be subject to 300 ~ 400 ℃ baking. Short arc welding process in general, can be all-position welding. Weld crack resistance and good overall mechanical resistance force. Important for welding the welding structure. Stable arc under the skin of drug dose, the amount of iron powder and binder, divided into low-sodium, low hydrogen iron powder low hydrogen potassium type and type, etc.
(8) Pharmaceutical skin types: graphite-type Power Supply: AC or DC main features: drug skin contains large amounts of graphite, usually used for cast iron or hardfacing electrodes. Low carbon steel welding core, the welding performance is poor, splash more, smoke more, less slag, suitable for flat welding. The use of non-ferrous metal welding core, they can improve their process performance, but the current is too large is not easy
(9) Pharmaceutical skin types: of base-type Power Supply: DC Features: drug skin contains large amounts of chloride and fluoride, mainly for aluminum and aluminum alloy Welding Rods. Hygroscopicity strong, welded before drying. Drug skin low melting point, melting fast. DC power supply, poor welding, short arc corrosive slag after welding required hot water addition, for drugs containing large amounts of iron in the skin of the electrode, can be called the iron rod. Then, follow the main component of skin electrodes drugs, can be divided into iron titanium, iron titanium calcium type, ilmenite-type iron powder, iron oxide-based, iron powder low hydrogen type, which form the iron powder electrode series.

By the Thermal Power Research Institute, Suzhou and Shanghai Electric Power Plant Co., Ltd. to build complete "nuclear power plant made ​​WB36CN1 steel rod development and application of new research" project April 9, identified by the Commission related to the assessment of the domestic.

The project developed a nuclear power plant made ​​WB36CN1 match J607CrNiMo steel rod to achieve control of Cr technical requirements, will help improve the flow accelerated corrosion resistance of welded joints (FAC) the ability to work with steel base material WB36CN1 good match, and according to DL / T 1117 2009 "conventional island nuclear power plant welding procedure qualification procedures" and DL / T 1118-2009 "conventional island nuclear power plant Welding Electrode" for the welding procedure, developed to meet the WB36CN1 steel Welding Rods welding requirements.

Identification Committee that the results of a national initiative, the technical performance indicators and similar foreign products relatively electrode can be used for nuclear power to replace imported products with WB36CN1 steel welding, agreed to adopt scientific and technological achievements, and suggested the development of this project as soon as possible electrode put into mass production, promotion and application.
