Q: A022 what kind of material is the welding rod?: A022 E316L-16 welding equipment for urea and synthetic fiber

Q: Electric welding machine welding, welding rod old stick metal, welding rod burning red, very scary: Several heroes are very practical, welding electrode drying before use is also necessary!

Q: What welding rod should be used for welding between No. 20 and No. 45 steel?: J427When welding, pay attention to the small current at the bottom, and the weldability of No. 45 steel is poor

Q: What kind of welding rod does Q345 steel use?: Weldability of Q345 steelQ345 low alloy high strength structural steel with carbon content of 0.18% ~ 0.20%, tensile strength equal to 470-630MPa. Q345 steel alloy content is less, good weldability, welding generally without preheating.But because the Q345 steel hardened tendency is slightly larger than the low carbon steel, so at low temperatures (such as winter outdoor operations) or welding in high rigidity, large thickness of the structure, in order to prevent the cold crack, need to take measures to preheat. The preheating temperature of 16Mn steel at different plate thickness and different environmental temperature is shown in table 8.Q345 steel welding should be used in E50 type electrode, such as E5015, E5016 for alkaline electrode, the structure is not important, also can choose E5003, E5001 acid electrode. For the weldment with small thickness and narrow groove, E4315 and E4316 welding electrodes can be used.Table 8 preheating temperature of welded Q345 steelThickness of weldment (mm) preheating thermometer at different temperatures (DEG C)More than 16 of not less than of-10 DEG C - C without preheating preheated to 100 to 150 DEG C16 ~ 24 of not less than 5 DEG C 5 DEG C without preheating preheated to 100 to 150 DEG C25~40, not less than 0 degrees Celsius, not preheated, 0 degrees below 100~150 preheating temperatureMore than 40 are preheated 100~150 degreesSubmerged arc welding of Q345 steel H08MnA welding wire with flux HJ431 (open I butt welding wire with flux HJ431) or H10Mn2 (plate groove butt), when the deep groove weld of thick plate welding, welding wire with flux HJ431 H08MnMoA should be used.Q345 steel is the most widely used low alloy steel in our country at present,

Q: Please tell me the current corresponding to various types of welding electrodes in detail!: Sectional area of electrode x15Such as 4mm welding rod, =2x2x3,14x15=180

Q: Drawings require E43 electrodes, the market says 422 of the electrode, the package is written on the CFE422! Q235B seamless steel pipe should be welded. Can you tell me what kind of electrode should be used then?: Dissimilarity。 E43 is the electrode type, and J422 is the electrode (concrete) brand.Welding rod brand: J422, model: E4303 belongs to titanium calcium type low carbon structural steel welding rod. For Q235 grade low carbon structural steel welding. Acid welding rod. AC welding machine DC welder and welding rod. Good welding process, easy to remove slag. All position welding.It should be said: E43 model series welding rod, and J42 brand series of welding rod matching specifications.Such as: Brand: J422, corresponding model: E4303,Brand: J426, corresponding model: E4316,Brand: J427, corresponding model: E4315.

Q: Why should the electrode be baked before use?: I don't want to tell you anything that is very theoretical and very textbook. Our project is very wet in the south, so the steel production base often does.The main reason for baking the electrode is (or to prevent) the welding rod from being wetted.Welding rod after wetting, in the welding of workers will indirectly cause more slag, more bubbles, the current is not good control, burn the main tendons, and the strength of the steel bar connection will not meet the design requirements.That's all.

Q: What brand of carbon steel electrode is the best?: For welding rod:Domestic brands, then, the best in the Atlantic, where the CHE58-1 is simply a classic product.Foreign brands, then, Lincoln, Esab and so on are also classic brands, Olin Kang is the best.

Q: Q345q what kind of welding rod is used for steel welding?: E5015 or E5016,J506 or J507

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
