Q: What grade of welding rod is used for three grade steel welding?: The type and quality control requirements of welded joints are shown in the welding procedure for reinforcing barsAccording to the form of welded joints: E5003, E5503 and so on.

Q: What welding rod does 20CrMnTiH use?: 1, 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 to provide pictures2 Cr Mn Ti carbon steel and permeability, the higher hardenability, the quenching conditions, with high strength and toughness, especially with high strength and impact toughness of.20CrMnTi steel surface carburizing hardening. Good processability, small deformation, anti fatigue performance is good. Use: for the gear, shaft, piston type accessories. For cars, aircraft of various special parts.3, the characteristics and scope of application: is the good performance of 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..4, J857Cr low alloy high strength steel welding rod, 857Cr low-alloy high-strength steel welding rod comply with: GB E8515-G equivalent: AWS E12015-G5. Description: J857Cr is low hydrogen and sodium type skin with low alloy and high strengthPreheat 200 before welding and 500-700 (or dark red) after soldering

Q: J807 electrode specification: Brand: J807, model: E8015-G.Fused metal chemical composition: carbon is less than or equal to 0.09%, manganese is greater than or equal to 2 and less than or equal to 0.40%%, silicon molybdenum, 0.80 ~1.00%%Belongs to low hydrogen and sodium type low alloy high strength structural steel welding rod. DC reverse polarity is adopted. All position welding. Excellent manufacturability and crack resistance.Used for welding of 14MnMoNbB steel and other low-alloy structural steel of corresponding strength.

Q: What kind of welding rod Z208 is the main material for welding?: Z208 is a steel core graphite cast iron electrode, mainly used for cast iron heating (generally heated to 600-600 DEG C) welding, a homogeneous weld electrode, cheap, low cost, but the welder's labor intensity, poor working conditions.

Q: Electrode: 506--J48-56 junction, Tianjin Bridge Welding Materials Group Co. Ltd. production. Is it possible to use an AC welder?: J506 welding rod, using DC welder, AC welder can.

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: How long is the effective period of welding rod?: If the stock period exceeds the prescribed time limit, the electrode, flux and flux cored wire must be re examined before the relevant functional departments can be issued and used. complexTest principle to check whether the welding material may affect the quality defects, generally limited to appearance and process performance test, but there are doubts on the performance of welding materials, can increase the necessary inspection item.The prescribed time limit may be determined by the following method from the date of production:A) the period of recommendation for welding materials, quality certificates or manuals;B) a low hydrogen type welding material for acid welding materials and moisture resistant packages, sealed for two years;C) graphite type welding materials and other welding materials for one year.

Q: What kind of welding rod does 1Cr13 steel plate use?: Usually in 1Cr13 and other dissimilar materials welding, choose A302 welding rod, welding should not preheat and after heat, but after welding, it is best to increase heat treatment (of course, no heat treatment is also no problem)It is better to use G202 or G207 if welding of 1Cr13 same kind of material, preheating before welding, heat after welding and heat treatment

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.
