Welding Accessories Welding Electrode E7018
E7018 Welding Electrode is an iron powder, low hydrogen type welding electrode used for welding 490 MPa class high tensile steel.
The weld metal has excellent mechanical porperties, toughness and crack resistibility. E7018 contains mush ironpowder in its coating and highly efficient welding can be conducted.
• Much iron powder contained in the coating gives high efficiency.
• Produces the weld metal of excellent toughness and crack resistibility because of the characteristic peculiar to the low gydrogen type electrode.
• Good with both AC and DC.
• All position welding for 490 MPa class high tensile steel is performed, in the fields of ship building, machine and steel structural fabrications.
Product is available in Size 2.6mm, 3.2mm, 4.0mm, 5.0mm.
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: Requirements for welding electrodes for temperature and humidity
- Storage should be kept at 10---25 degrees Celsius and less than 50% relative humidity.
- Q: What are the characteristics of welding rod E6010? What are the main points of operation?
- E6010 type welding rod belongs to all position welding rod of cellulose, which has great arc blowing force. When using, direct current welding machine and reverse polarity welding method are adopted, the lower welding is fast, and the welding speed is faster.
- Q: Excuse me: can J422 welding rod not be used for HRB335 steel bar welding? Where there is such a rule, I see the norms can use ah.
- Lap welding, welding joint welding stress is too large, easy to break joints, it is not recommended. Welding steel bar has a special butt welding machine
- Q: How long is the Golden Bridge welding rod 427 electrode drying?
- 420 degrees dry 24 hours, 200 degrees heat preservation 24 hours.
- 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 does 70 of the e7015 electrode mean?
- The method of welding rod number is as follows: the welding rod letter "E" means welding rod;The top two digital said the minimum value of the tensile strength of the deposited metal is kgf/mm - unit. (70kgf/mm = - 690 MPa)Third digit electrode welding position, "0" and "1" electrode for all position welding (flat, vertical, horizontal, upward), "2" is suitable for welding and fillet welding electrodes, "4" is suitable for vertical down welding electrode;The third and fourth bit numbers indicate the type of weld current and the type of coating.After fourth digits, additional "R" is added to indicate the resistance to moisture absorbing electrode. Additional "M" is used to indicate the resistance to moisture absorption and mechanical properties. The electrode with special requirements is added with "-1", indicating that the electrode with special requirements for shock performance is attached.
- Q: Can white steel electrode weld cast iron?
- I have not used white steel electrode, used 506 is not bad
- Q: What is the difference between THJ506 welding rod and THJ422 electrode?
- 1, THJ506 electrode and THJ422 electrode in use is different.2, first of all, an acid welding rod, and an alkaline electrode.3, second electrode class is not the same, one is 40, one is 50.4, in the use of acid welding rod, DC welding machine can be welded.5, the basic welding rod welding machine is usually required to welding, because it requires welding machine no-load voltage is relatively high.6, THJ506 electrode in the description, it is possible to AC welding machine can be used, but in actual use, arc is very difficult, and even welding machine is not good, even the arc can not play, even if the arc, continuous welding is still very difficult.
- Q: When welding, the welding rod sometimes can easily stick to the weldment, and it is not easy to arc. The ignition is also easy to extinguish. Why is that? What happens when this happens?
- 1, welding current is too small.Please refer to the instruction of welding current in electrode box, choose the suitable welding current according to the welding position.2 basic electrode welding with AC welder.J426, J506 and other low hydrogen potassium welding electrodes must be welded with BX series alternating current welding machine with no-load voltage above 70V. The lower the no-load voltage of the welder, the easier it is to stick the welding rod.3, the welding rod model is wrong.J427, J507 and other low hydrogen sodium welding rod, unlike low hydrogen potassium electrode containing arc stabilizer, the welding rod must be welded by DC welding machine. AC welding machine will stick welding rod, cannot arc.4, improper operation. Basic electrode (low hydrogen potassium welding rod, low hydrogen sodium welding rod, etc.) shall adopt the method of striking and striking arc. Just as a match, the end of the welding rod and the construction of contact, a slight rub can ignite the welding arc. If the direct striking method is used, the welding rod is unavoidable.5, technical problems. The arc welding rod should lift the arc 1-3 millimeters rapidly and enter the normal welding mode. Otherwise, long time welding rod and workpiece short-circuit will dip electrode.
- Q: What kind of material is E4303 electrode?
- E4303 is the international standard, the J422 electrode is a common name, it is a kind of acid electrode, titanium calcium coating, J structural steel electrode, 42 42kg/mm2 tensile strength of weld metal, melting the tensile strength of not less than 420MPa
