- 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 steel bars, JGJ 18E43xx can only be used for Grades 1 and 2Checked:3 grade steel, according to the form of welded joints: E5003, E5503 and so on
- Q: When welding, for example, 3.2 of the electrode should choose how much current
- The current selection depends on the thickness of the steel plate welding you, if it is a few thick milimeter can use 150A 200A to 10 mm thick, can use 180A to 250A.Pu steel plate for large current will be easy to wear thick steel plate welding, welding with small current will not!
- Q: In addition, when the basic electrode is DCEP welding, the hydrogen content is lower than that of DCEN?
- The key point is that the welding rod can use acid and basic electrode, AC only use acid electrode, and arc welding with basic welding rod. The quality of DC welding and arc stability are better than those of AC welding. If it's an electric welder, it's AC
- Q: What is the difference between tin strip and electrode?
- Tin is made of tin and has a low melting point. It is commonly used for the connection of small items such as circuit connections of integrated circuits. The principle is that the crystal is melted by heatingThe outer electrode is a mixture of phosphorus and other combustible material, the middle is iron, high melting point, used to connect large metal objects, the work is a glare, hurt the eyes, the working principle is the crystal of heat melting and high pressure arc discharge
- Q: What are the main differences between automatic submerged arc welding and rod arc welding?
- Automatic submerged arc welding is suitable for large current welding of 300-800A, and welding arc uses submerged arc welding flux to effectively protect molten pool. The bead forming is beautiful, tensile resistance is strong, welding defects are reduced, and deposition efficiency is high. Welding rod welding efficiency is low, welding current between 60-200A, welding dust is big, harmful to human body.
- Q: Can ordinary electrode be used for welding cast iron?
- No way！ Cast iron electrodes must be used! Ordinary welding rod welding porosity is too much, not solid.
- Q: T107 purple copper electrode welding with what
- Inverter type DC welding machine is recommended. DC reverse short arc welding is adopted.Arc instability of AC welding machine.Silicon rectifier DC welding machine is affected greatly by network voltage fluctuation, reactor is not electronic current control, welding parameters are not accurate enough. Welding quality can not be achieved.
- Q: Can white steel electrode weld cast iron?
- White iron welding electrode can be cast iron, but it is recommended to use pig iron welding, because white steel welding rod after welding is easy to crack.For welding of carbon steel and low alloy steel welding core, are mostly made of low carbon steel as the core, and adding manganese, silicon, chromium, nickel and other components (see wire national standard GB1300 - 77). The reason of low carbon is a low carbon steel wire plastic, wire drawing is relatively easy, on the other hand can reduce the CO content of reducing gas, reduce spatter or porosity and increased weld metal solidification temperature, favorable for overhead welding. The addition of other alloy elements mainly guarantees the comprehensive mechanical properties of the weld, and also has some effect on the welding process performance and the removal of impurities.
- Q: In the pipe welding, a welding rod welding in the replacement of an electrode should be how to deal with joints?
- 1, if the strict requirements for pipeline welding, portable welder hammer medicine skin clean, in a welding rod arc welding joint has less to stay in the rear has deposited metal (no more than a centimeter can) for a moment, a swing, further the welding slag burn surface welding quality;2, in large long-distance pipeline, welding joints must be cleaned with a sand turbine, and then the next step of welding.
- Q: 302 which kind of electrode should be used for welding stainless steel with iron?
- Stainless steel and cast iron welding, of course, is made of cast iron welding rod, using stainless steel welding rod, crack is not good, and the strength will not be too high. If the connection strength requirements are relatively high, you can choose MG289 welding rod, welding effect must be no problem, welding is to pay attention to the electrode angle can be. Here are the instructions. (now fakes are a lot of care.):MG289High strength alloy for welding of clean cast iron.The weld deposits can be machined.Specially designed for welding unclean and greasy cast iron.Low pressure water welding for cast iron pipes.Alloy metal core design, with unique flux, with the anti crack function.Easy to weld at any position.Purposes such as:- cast iron and steel weldsWelding of different cast irons- drive gear box- grey cast iron, malleable iron or ductile iron
