- Q: What does E4315 mean on the electrode?
- E stands for "43" electrode, the tensile strength of the minimum value, "1" means 0 and 1 indicate the position of welding, suitable for all position welding, suitable for welding and 2 horizontal fillet welding, 4 for vertical down welding, welding current "5" type and type of coating.In fact, J427 low hydrogen electrode
- Q: J807 electrode specification
- Gas shielded flux cored wire with high strength steelSHJ807Description: SHJ807 is a metal cored low alloy high strength steel welding wire. When welding, the welding wire is connected to the positive pole and 80%Ar+20%CO2 mixed gas or 100%CO2 is used to protect the welding wire. The welding process has good performance and high welding efficiency. Deposited metal has good crack resistance and high toughness. The workpiece should be preheated in the range of 250~350 centigrade before welding and be treated by tempering at 620 DEG C after welding.Application: it is used for welding high strength steel of relative strength grade, and can also be used for surfacing of ordinary wear-resistant parts or for transition layer of hardfacing parts.Typical chemical composition of deposited metal (%)Ingredients C, Mn, Si, S, P, Cr, MoThe measurement value of 0.065 1.63 0.3 1.05 0.48 0.025 is less than or equal to 0.025Typical mechanical properties of deposited metal: (690 * 1H tempering)Tensile strength (o b) Mpa yield strength (by 0.2) Mpa (5)% elongation impact energy of Akv (-40 C) JMeasured value 8207601838Recommended parameter: (DC+) (1.2mm)Welding current (A), welding voltage (V), dry stretch length (mm), gas flow (l/min)200~260 28~32 15~25 20Matters needing attention：Remove rust, oil stain and moisture before welding.Remove welding slag between welding layers, and avoid slag inclusion.When welding, preheating and post heat treatment are carried out according to process requirements.Welding wire should be kept in a cool and dry place. It can be used up in time.
- Q: Types of electrodes
- Ask me, the welding rod according to the diameter commonly used has 2.5, 3.2, 4. According to the use of ordinary, stainless steel, cast iron, wear-resistant electrode. Among them, the ordinary electrode according to grade 422506 and 502, stainless steel 102, 132, cast iron points 302, 402. Electrode wear is generally used in digging bucket, carbon and some high wear resistant. These are commonly used welding rod, and some special electrode, the amount is very small. Generally speaking, the higher the grade of the electrode, the more expensive the price. Little dragon, what else do you know? Ask me!
- Q: J422 welding rod, 10MM steel plate.
- A flatThe angle between the welding wire and the welding torch is kept at about 90 degrees;Two. Vertical weldingThe welding torch shall be tilted upwards along the welding direction, and shall be maintained at 60--80 degrees in general with the weldmentThree, transverse weldingThe left welding method is adopted for the thin part. But the welding torch should also be tilted upwards so that the flame will flow directly towards the weld seam. The molten metal will be prevented from flowing out of the molten pool by the pressure of the airflow;Four. Overhead weldingWhen welding the first layer of the weld seam with groove, the welding rod is 90 degrees to the sides of the groove. With the welding direction of 70 - 80 degrees angle, with the shortest arc to do push and pull action, the pool should be thin, not thick, and to ensure good fusion with the base metal. When the bath temperature is too high, the arc can be lifted, and the temperature will be slightly lowered. When welding all the other layers, the welding rod will swing and make the arc stabilizing action on both sides.
- Q: What kind of welding rod used for cast steel?
- Cast steel can be divided according to the composition of low carbon steel, medium carbon steel, different components of the electrodes used is not the same, if it is a low carbon composition, the common electrode, such as E4303 (J422) on it; if it is steel components, should be used in high strength structural steel electrode, such as E5015 (J507) E5515 (J557), welding welding and preheating, to prevent cracks.
- Q: What kind of welding rod is Mt -12?
- MT-12 welding rod is one of the key brand export commodities exclusively operated by Tianjin metal and mineral import & Export Group co..MT-20 (J422) and MT-12 (J421)MT-12 is J421 (E4313) carbon steel electrode titanium type coating. AC / DC, suitable for all position welding, good performance, and easy arcignition. Cover welding intermittent welding requirements and is especially suitable for small and thin short welding surface finish.
- 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: There are some electrode home models are R312, R317, J507, J422 these are used for what is now know, 2 mantissa is acidic, mantissa 7 is alkaline, I want to know that the four electrode is used to weld what, for example which used for stainless steel, which is used for carbon steel,
- The carbon steel welding rod E represents the welding rod, and the first two figures indicate the minimum value of the tensile strength of the deposited metal. The third position indicates the welding position, and the three or four digit combination represents the type of welding current and the type of the coating.The stainless steel electrode "E" represents the electrode, and "E" is the digital code indicating the chemical composition of the deposited metal. "-" the two digits behind it indicate the type of the coating, the position of the weld and the type of welding current.Specifically, you can see GB5117, GB983.Such as structural steel electrode J422, J is steel structure code, 42 said that the tensile strength of weld metal grade (MPa value 1/10), said at the end of the 2 type of coating and the type of welding power source; and as the austenitic stainless steel electrode, A132, A austenitic stainless steel electrode of the code, the first digit said the main chemical composition of weld metal (Cr, Ni) level consists of second digits, in addition to Cr, Ni other metal components brand variety.The electrode model is based on the mechanical properties of the weld, the type of the coating, the location of welding and the type of welding current. Such as E4315, E is said 43 electrode, said the tensile strength of the deposited metal is minimum, third digits 0 and 1 indicate the position of welding, all position welding, suitable for welding 2 and 4 for horizontal fillet welding, vertical down welding, the last one said the current type and type of coating.
- Q: What's the model of lap welding for two grade steel bars?
- You should first look at what is the project of the Ministry of communications and the Ministry of water resources, the other I know better, the Ministry of construction and the Ministry of Railways is not clear, each industry standard is not the same, so you have to figure out is what industry.If it is the Ministry of communications project, two steel bar can use E43 electrode, but the Ministry of water resources can not, need to use E50. These are found on the corresponding construction codes for reinforced concrete
- Q: What welding Q235 and 16 steel, please enlighten Masters
- If you do not answer the question, the general carbon steel electrode will do, such as J422, J506, and so on, and so on, what you have on hand;If you need a large amount of business, choose a cheaper one;If you answer the questions on the book, use E40, typically J422.
