5.FAQ
Q: Are you a manufacturer?
A: Yes, we have been in providing the professional products in Welding Rod over 10 years.
Q: Can I get the sample?
A: Yes, free samples are prepared for your test.
Q: How long can we get the goods after purchased?
A: Usually it needs about 20 days, the exact time is according to the detail.
- Q:Why should the electrode be baked before use?
- Ordinary carbon steel electrode can not be used, but other electrodes, especially white steel, must be baked, because the welding rod welding when there will be holes
- Q:Where is the difference between 422 electrode and E50 electrode? HRB335 steel cage can use 422 electrode
- Difference between J422 welding rod and E50 welding rod:The strength of J422 is 420MPA, and the brand is E4303.E50 electrode strength of 50 0MPa, common E50155016, etc., equivalent to J506, J507, J is the electrode brand, Chinese knot Jie (structural steel) of the first spell. The parameters behind the letter include strength, skin, power supplies and so on.E is the electrode type. E refers to the electrode, and the figure in the back is usually 4 figures, indicating 12 strength, 34 welding position and welding current type and type of coating.What is the difference between the type and grade of welding rod?The model containing strips is stipulated by the national standard, and its meanings include the type of the coating, the type of alloy, the strength, the applicable welding power, etc., and the classification is very fine. The brand of welding rod is a relatively common term formulated by manufacturers. Such as electrode model E4303, the corresponding brand is J422
- Q:E43XX welding electrodes are often used in welding of steel structures, of which 43 is indicated
- 1) the brand of welding rodTaking structural steel as an example: designation. JXXX, J for structural steel welding rod, third figures, representing the type of leather, welding current requirements, first, second number: on behalf of weld metal tensile strength.2) model of welding rodThe type of welding rod is determined by the relevant national standards and international standards. EXXX, structural steel, for example, model establishment method for the letter "E" said electrode, first, second said that the minimum tensile strength of weld metal, third digit electrode welding position, the third, fourth digits of the welding current type and type of coating.For example, the model is E4303 brand, that is, J422 J representative of institutions, steel electrode 42, said tensile strength 2, indicating the skin type
- Q:Cast 308 pure nickel cast iron welding electrode. What shall be used for welding?
- The iron parts to be machined after welding.No machining is OK, but the cost is high.
- Q:Where to buy electrodes, how to buy online, welding rod is always not assured
- Mechanical and electrical market to buy it, each region has the corresponding welding rod manufacturer's general sales agent, go to the market to buy it, our company has a procurement, is to buy Wire online, and then cheated, pay attention to good.
- Q:Does the welding rod have a shelf life?
- This does not necessarily depend on your preservation of the environment and the variety of electrodes, and some electrodes have been preserved for more than ten years, the use of performance is still very good. As long as it is not damp and the skin falls off, it can continue to be used.Material shelf life is not strictly required, the pressure vessel required if more than one year, should carry on the inspection, inspection qualified can continue to use, every year to conduct a test, you can still continue to use qualified.If the welding pool conditions, welding save no moisture, no deterioration, after inspection and acceptance, can still be used.If not assured, you can downgrade to adopt. There is not willing to do more information (welding rod to continue inspection of qualified data), can also be downgraded. Other industries, did not see the relevant standards requirements.Our welding wire has been produced in Japan in 1949. The welding rod has been produced in Japan in 60s and 70s. It has been well preserved. Now the chemical field inspection and maintenance are still in use. The effect is very good and the quality is not a problem.
- Q:What is the welding process of duplex stainless steel 2507? What electrode?
- The brand of welding rod is: 2209. The electrode must be dried before welding. The drying process is 2 hours at 250 C, and the welding rod must be insulated with electrode.
- Q:Generally, how many packs are in one case and how many KG in one package?
- A case of four bags, a packet of five kg
- 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:Q345q what kind of welding rod is used for steel welding?
- J502 (acid welding electrode E5003): suitable for general structures of Q345-A, Q345-B;J506 and J507 (basic electrode E5016-A1, E5015-A1): Q345-B for important structures;J506 and J507 (basic electrode E5016-C1L, E5015-C1, L): Q345-C for important structures;J506 and J507 (basic electrode E5016-G, E5015-G): Q345-D for important structures;J506 and J507 (basic electrode E5016-E, E5015-E): Q345-E for important structures.
