Q:What kind of welding rod is used for No. 55 steel?
No. 55 steel is made of genuine WEWELDING 600 welding rod.Because the 55 steel for high strength steel, treated with surface hardness and high strength, plasticity and toughness but poor machinability of medium, weldability, hardenability, water quenching is the tendency for crack formation, welding crack resistance of the need for a very ideal electrode to WEWELDING 600 welding, ensure tensile strength requirements of crack resistance and use of the process after welding.Characteristics of WEWELDING 600 special alloy steel welding rodWEWELDING 600 is a low heat output, suitable for special nickel chromium alloy steel electrode welded all-round, universal design is extremely wide, the general strength of parent materials with high strength, excellent welding performance, stable arc, beautiful shape of seam, in oil, water and rust conditions can welding effect is excellent, can be welded different steel.Application of WEWELDING 600 special alloy steel welding rodSuitable 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.Technical parameters of WEWELDING 600 special alloy steel welding rodTensile strength: 125000 psi (862MPa)Yield strength: 90000 psi (620MPa)Elongation: 35%Hardness after welding: HRC23 (work hardening up to HRC47)Power supply: AC and DC dual use, DC DC reverse connection
Q:What kind of welding rod should be used for welding cast steel parts?
Ordinary steel welding, according to the general steel strength to choose, most of the structural steel welding rod, according to the strength of the cast steel of different levels, in turn can choose the type of electrode (or model) with J42 * (E43 * *), J50 * (E50 * *), J55 * (E55 * *)... Etc...
Q:Does the welding rod have a shelf life?
Welding rod has shelf life,The quality index of storage time exceeds a certain time limit, changes in different degree of quality (metamorphic). Various types of electrodes are stored for a long time, and sometimes white crystals are found on the surface of the electrode. This is usually caused by water glass. Packing should be improved to prevent moisture absorption of welding rod and must be properly kept in storage. All kinds of welding rod are seriously deteriorated, and the batch of medicine is seriously falling off. The welding rod should be scrapped.
Q:J422 electrodes are marked with "THJ422". What does TH represent?
J422 is the brand of welding rod GB. As for the TH is the enterprise stipulated grades, the first letter T should be on behalf of the welding electrode (strip of the first letter); second letters H, should be related to the electrode trademark or manufacturer's name.
Q:4 of the electrodes, what is the weight of a case?
As far as I know, the welding rod is not the pipe specification. They are 5 kilos a pack. One case is 20 kilos. At least the Atlantic has this kind of packing. There are two main kinds of welding rod. There is no need to be as complicated as the previous net friend, the acid welding rod and the basic welding rod. Acid electrode, that is, the most common, such as 422. This electrode is generally easy to use, not demanding, carbon steel, ordinary iron can be used, the basic electrode contains more. Mainly used for higher welding requirements. Boiler aspect. Such as 317.507.307., these 3 are carbon steel. There are 137.407 stainless steels. Also used for boiler pipes. Pressure vessel aspects. Specifications are common for 3.2, 4, 6, 2.5. That's all I know
Q:In the pipe welding, a welding rod welding in the replacement of an electrode should be how to deal with joints?
1, if the strict requirements for pipeline welding, portable welder hammer medicine skin clean, in a welding rod arc welding joint has less to stay in the rear has deposited metal (no more than a centimeter can) for a moment, a swing, further the welding slag burn surface welding quality;2, in large long-distance pipeline, welding joints must be cleaned with a sand turbine, and then the next step of welding.
Q:What kind of welding rod does Q345 steel use?
Ordinary welding rod can be, Q345 steel weldability is better.
Q:What welding rod should be used for welding between No. 20 and No. 45 steel?
No. 20 steel and No. 45 steel belong to dissimilar metal welding. Recommended electrode: J506 or J507.Steel No. 20 belongs to low carbon structural steel. It can be made of low alloy structural steel electrode with J422, J426, J427 and other grade strength.No. 45 belongs to medium carbon steel. The strength level of the matched electrode is J555 J556.Can use J50 series grade intensity of basic electrode welding rod, the electrode is lower than 45 steel J55 welding rod one level, higher than 20 steel J42 welding rod one level.Recommendation: J506 (E5016) low hydrogen potassium alloy structural steel welding rod;Or: J507 (E5015) low hydrogen sodium type low alloy structural steel welding rod
Q:What is the price of titanium - calcium welding rod and low hydrogen type electrode?
The calcium titanium electrode and the low hydrogen electrode are the type of electrode. The coating composition of titanium calcium type refers to the electrode with titanium dioxide and calcium carbonate, acidic and low carbon steel electrode, hydrogen electrode is the electrode with low hydrogen material such as low hydrogen sodium or potassium hydrogen based low carbon steel electrode is alkaline. The coating composition is different, so the welding process performance difference is relatively large, acidic carbon electrode process performance is stable, the basic AC / DC arc stability; alkaline and carbon steel electrode because of easily ionized material, arc stability is relatively poor, and many can only adapt to the DC welding welding, the weld metal the hydrogen content is low, so it can ensure the internal quality of weld. As for the price, can not be generalized, titanium calcium welding rod some prices higher than the low hydrogen electrode, but experience, low hydrogen electrode price than titanium calcium type electrode price is higher, about 500-700 yuan per ton. Because I manufacture welding materials.
Q:What welding rod does 20CrMnTiH use?
20CrMnTi is steel carburizing, carburizing steel is usually carbon, low carbon steel 0.17%-0.24%. The car with the drive gear is in manufacturing. The hardenability of Shanghai Kai Xin steel Cr Mn Ti steel to provide pictures infiltration of carbon steel, the higher hardenability, the quenching conditions, with high strength and especially with high toughness, low temperature impact toughness of.20CrMnTi steel surface carburizing hardening. Good processability, small deformation, anti fatigue performance is quite good. Uses: used for gear, shaft, piston type accessories. For cars, aircraft of various special parts. The characteristics and scope of application: performance good carburizing steel, high hardenability, carburizing after quenching with hard and wear-resistant surface and tough heart, has high low-temperature impact toughness, weldability medium, normalizing machinability is good. Used to manufacture the important parts, such as gears, gear rings and gear shafts, that bear high speed, medium or heavy load, impact and friction, which are less than 30mm. 18CrMnTi is widely used as a substitute for steel, carburized parts, in the automotive industry for the tractor. Under the high-speed section below 30mm. In heavy load or impact. And the important carburized parts, such as gear shaft. The friction ring gear. The gear shaft. The spindle. Sliding bearing. The crosshead. Claw clutch worm. Etc.. J857Cr high strength low alloy steel electrode J857Cr high strength low alloy steel electrode line: GB E8515-G AWS E12015-G: Description: J857Cr is a high strength low alloy welding preheating low sodium hydrogen coating 200 after welding tempering 500-700 (or dark red)
