E7018 is a low-hydrogen electrode with a high deposition rate for mild steel.
-Superior welding performance with either DC or AC.
-Superior mechanical properties: constant tensile strength and high impact value.
-Superior crack resistibility.
- 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: How many kinds of welding rod do you have?
- According to different circumstances, there are three kinds of welding rod classification method: according to the use of electrode classification, according to the main chemical composition of the drug classification, according to the characteristics of the drug after the melting of slag classification.
- Q: Why should the welding electrode prevent moisture? What happens if you get soaked by water?
- Shanpaolv ah, do not know it. The electrode coating can be used in the welding process to re metallurgical and protect the weld pool and improve the weld formation. The skin of the medicine is affected with dampness, resulting in deterioration of the titanium, iron and calcium in the coating, and losing the original chemical properties. Even when drying, the deterioration of the compound in the welding will also produce water vapor, itching, hydrogen and other harmful substances to weld metal embrittlement. The change of the properties of the crust makes its physical properties different from those of the past, such as heat conduction, conductivity, melting point, melting effect, etc.. Influence re forming, resulting in thermal oxidation, metal cooling, excessive stress concentration, quenching...
- Q: J422 welding rod, 10MM steel plate.
- How is caught in the electrode holder do not have much relationship. The key is the angle between the electrode and the workpiece, horizontal fillet welding is quite appropriate at about 45 degrees.
- 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: Can ordinary electrodes be welded to stainless steel? What's the effect?
- It's hard to solder. It's best to use soldered joints
- Q: What kind of welding rod is used for welding rail and ordinary steel?
- With J427 electrode, is now generally in accordance with the choice of high steel electrode types, such as manganese steel and ordinary steel, we must choose the basic electrode, with low strength steel electrode selection level, so choose 427 electrodes.Can check the specifications, such as: pressure vessel welding specifications, industrial pipe construction (welding) specifications, etc.
- Q: I now want to surface hardening of the roll, ready to use J506 welding rod continuous welding roll surface, how much surface hardness can be achieved?
- 1, J506 can not guarantee that there is no hardness after surfacing. It is recommended to use D047 welding rod.2, J506 is a low hydrogen potassium electrode, it is a kind of basic electrode, can be welded structural steel and typical Q235 steel, the tensile strength of E4315 is much larger relative to the common electrode, so the general welding force or by welding steel structure of dynamic load.3 roll is an important part of a rolling mill on a steel mill. It uses a pair or a set of rolls to roll and crush the steel. It is mainly affected by static and dynamic loads, wear and temperature changes during rolling.
- Q: Why can DC welding machine weld any electrode?
- Direct current, especially the direct current produced by the inverter DC welding machine, is relative to the power frequency AC welding machine. The arc is stable, the spatter is very small, and the arc is not easy to break. The welding parameters have almost no fluctuation under the influence of input voltage. Three phase welding machine also supports thrust current, hot arc ignition function. It can avoid sticking electrode when arc welding with basic electrode. If there is no frequency exchange of AC, it is difficult to weld slag hole. A metal with a high sensitivity to carbon is not susceptible to cracks in heat sensitive metals.Basic electrode J426 J506 can be AC DC welder dual-use. These two kinds of welding rod contain arc stabilizer. However, from the quality of welding, DC welding machine is much better quality than AC welder.
- Q: Who knows what welding electrode is?
- Welding rod is the main raw material of welding for national defense, machinery, chemical, metallurgy, mining, shipbuilding, automobiles, tractors, agricultural machinery, construction, repair and other industries. Titanium dioxide is one of the main raw materials of welding rod industry, and the three kinds of welding electrodes, such as titanium, titanium, calcium and ilmenite, should be made of titanium dioxide, which accounts for more than 70% of the total electrode output. Therefore, the annual needs are large and the quality requirements are high.Titanium dioxide is the main components of the welding surface of the medicine in the skin, it is the good welding slagging agent and deoxidizer, diluent, adhesive and stabilizer. The welding slag made by the utility model has the advantages of low melting point, small viscosity, alternating current and direct current, and the utility model has the advantages of quick arc operation, stable arc, easy slag removal, good welding seam and good mechanical performance. Titanium dioxide deoxidization ability in medicine in the skin is also very good, in the welding process can protect the molten metal to prevent the oxygen in air or nitrogen penetrated weld decreased weld strength and plasticity, also the formation of titanium nitride, titanium and nitrogen stable, quickly into the slag, thereby eliminating the influence of nitrogen on weld. At the same time, titanium dioxide has a strong adhesion, in the electrode manufacturing process can reduce the amount of water glass, so that the surface of finished products smooth, easy welding point arc
