Q:What is the difference between electrode type and brand?
J422 acid electrode type GB E4303Structural steel welding rod, weld metal tensile strength of not less than 420Mpa, titanium oxide calcium type leather, AC and DC dual-use, mainly for welding low carbon steel and low strength alloy steel, such as 09Mn2 and so onJ427 basic electrode type GB E4315Structural steel welding rod, weld metal tensile strength of not less than 420Mpa, low sodium hydrogen type leather, DC reverse welding, mainly used for welding of important low carbon steel and low alloy steel, such as 09MnSi, etc.
Q:What kind of welding rod is used for Q345R steel plate welding?
Q345R is an ordinary low alloy steel. It is commonly used in boiler and pressure vessel. The delivery status is hot or normalized, low alloy steel. The performance is similar to that of Q345 (16Mn) (the yield strength of 16mm steel plate is greater than 345Mpa), the tensile strength is (510-640), the elongation is greater than 21%, and the impact strength of zero V is greater than 34J. E5015 calcium electrode is recommended.
Q:What kind of welding rod needs baking?
1, ordinary carbon steel electrode without baking, it is necessary to roast pig iron electrode can improve the quality of welding electrode 2, the storage time is too long when damp, but not the core rust, coating without deterioration, electrode after drying, can keep the original performance and does not affect the use.The electrode drying conditions of various types of drug skins are as follows (reference value):The baking temperature of acid welding rod is 150~200 1HThe baking temperature of alkaline welding rod is 350~400 1HThe baking temperature of cellulose electrode is 80 DEG C and the temperature is 1.5 ~ 2HThe baking temperature of graphite type electrode is 200 1H
Q:What kind of welding rod does Q345A board use?
Q345A (16Mn) is a low carbon structural steel. The electrodes that match the grade strength are the J50- series (E50--)Non important construction can be welded with J502 (E5003) titanium calcium type acid welding rod. The welding rod is good in welding technology and easy to remove slag. The electrode is cheap and suitable for AC welder and DC welding machine. The disadvantage is that the toughness is inferior to the basic electrode.The most important structures can be welded with J506 (E5016) low hydrogen potassium basic electrode. The electrode is suitable for welding of alternating current welding machines with no-load voltage equal to greater than 70V and load rate equal to greater than 60%. And welding of DC welding machine. The electrode contains arc stabilizer, suitable for AC DC welding machine welding.An important structure, such as a rigid larger member, a pressure vessel. Or other structural parts requiring higher welding. Using J507 (E5015) low hydrogen sodium type basic welding rod welding. The electrode does not contain arc stabilizer. Only AX arc welding generator, ZX5 SCR direct current welding machine, ZX7 inverter type DC welding machine welding. ZXG series silicon rectifier welding machine is affected by the fluctuation of input voltage, so it can not be used.
Q:12 chromium vanadium molybdenum with what electrode?
R312 welding rod or welding wire, model is E5503-B2-V,Or R317 electrode or wire, the model is E5515-B2-V.
Q:Type meaning of welding rod
The method of welding rod type is as follows:The letter "E" said the first two bits digital electrode; the minimum tensile strength of the deposited metal; third digit electrode welding position, "0" and "1" electrode for all position welding (flat, vertical, horizontal, upward), "2" is suitable for welding and fillet welding welding, "4" is suitable for vertical down welding electrode; said welding current type and coating type third and fourth digit combinations. After fourth digits, additional "R" is added to indicate the resistance to moisture absorbing electrode. Additional "M" is used to indicate the resistance to moisture absorption and mechanical properties. The electrode with special requirements is added with "-1", indicating that the electrode with special requirements for shock performance is attached.
Q:How are the electrodes made up?
The electrode composition is divided into two parts, metal core and coating (coating). It is composed of manganese, silicon, chromium, nickel, iron alloy, organic substance and so on.Core: generally use low carbon steel as the core, and adding manganese, silicon, chromium, nickel and other ingredients.Coating: Minerals (such as marble, fluorite etc.), iron alloy and metal powder (such as manganese, ferro titanium), organic matter (such as wood powder, starch), chemical products (such as titanium dioxide, water glass, etc.).
Q:304 can I use A022 welding rod?
Sure。 304 stainless steel, A022 stainless steel electrode.
Q:What welding rod does 16MnDR use?
16MNDR can use E5015 low temperature welding rod.E5015 low temperature welding rod:Features: low hydrogen and sodium type low temperature steel electrode with nickel, direct reverse welding, all position welding, and welding metal still has good impact toughness at -60 centigrade.Uses: welding -60 degrees, low temperature steel structure, such as 13MnSi63, 09MnNiNb, E36 and so on.Material (deposited metal chemical composition):C Mn 1.2-1.7 = 0.07 Si = 0.5 Ni S = 0.035, P = 0.035, 0.2-1Other: B = 0.003, Ti = 0.03
Q:What kind of welding rod should be used for welding cast steel parts?
WE600 special alloy steel welding rodapplicationSuitable for welding of tool and mould, high-speed tool steel, hot work tool steel, steel, cast steel, T-1 steel, Nai Zhengang, vanadium steel, spring steel, martensitic stainless steel, austenitic stainless steel, ferritic stainless steel, and the unknown as well as between the various different types of steel welding etc.. Such as high pressure valves, broken bolt clearance, shaft transformation, etc., the effect is very satisfactory.
