- Q: What kind of steel bars are used for the two electrodes?
- J422 welding rod is mainly used for welding low carbon steel structure and low strength low-alloy steel, such as A2, No. 20 steel, No. 35 steel, etc..J502 welding rod is mainly used for welding low strength carbon steel structure and alloy steel, such as A3, No. 45 steel, 16Mn and so on.J422 welding rod and J502 welding electrode are common terms, corresponding to international standard brands are E4303 and E5003 respectively. Is a kind of acid electrode, titanium calcium coating, J structural steel electrode, 42 and 50 respectively, the tensile strength of the weld metal (more than 420MPa and more than 500MPa), said 2 electrode for all position welding (welding, welding, overhead welding, horizontal welding).
- Q: What kinds of welding electrodes are used in the copper tubes for air conditioning? What's the difference?
- Two: copper electrode and silver electrode
- 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: What are the main differences between automatic submerged arc welding and rod arc welding?
- Automatic submerged arc welding; the current is higher than the manual arc welding; the welding wire is thicker than the welding electrode; the speed is fast; the efficiency is high; the operation is easy; the pores are not easy to produce; the width of the weld bead and the depth of melting are high.For individual welder hand arc welding technical level change, high difficulty, low efficiency, especially for more than 20, more than 20 of the slab thickness, is not easy, single pass welding slag cleaning difficult, but cannot be compared with manual arc welding submerged arc welding in all positions
- Q: Please tell me the current corresponding to various types of welding electrodes in detail!
- Empirical formula for welding current and electrode diameter: I=dk I--- welding current (A); d--- electrode diameter (mm); k--- empirical coefficient (30~50)Welding current of phi 2.5 electrode is 50A ~ 80AWelding current of phi 3.2 electrode is 100A ~ 130AWelding current of phi 4 electrode is 160A ~ 200AMore than 4 of the diameter welding current is 200A ~ 250A
- Q: How many kinds of welding rod are there? What's the name? What is the use?
- There are many kinds, not less than 100 kinds, welding plastic, cast iron, ordinary steel, alloy steel, stainless steel, etc.
- 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: What is a welding rod?
- It's "glue 'for welding metal."
- Q: How thin is the smallest electrode?
- The smallest electrode is the diameter of the electrode (mm) 1.6, the welding current (A) 25~40.
- Q: Hand welding electrodes 3.2 and 4 which are more commonly used?
- Electrode core diameter, that is to say, 3.2 of the electrode core is 3.2 millimeters in diameter, and 4 is 4 millimeters in diameter.The diameter of the welding rod is large, and the current should be larger when welding. High current, high efficiency, can be used in relatively thick plate welding. On the contrary, relatively thin plate welding, should choose a smaller diameter welding rod.Electrodes commonly used in three specifications, 3.2, 4, 5. Civil J422 and J506 more commonly used, industrial use of J507, J427 more. But the civilian use of 3.2 diameter more.
