When 507560 electrodes are used at the same time, which electrode should be selected?
1, J506 welding rod, J507 are basic electrode.2, J506 welding rod can be AC and DC dual-use.3, J507 welding rod can only use DC welder.4, if there is no DC welding machine should use J506, if J506 arc difficult, you can consider using J502.5, J507 welding rod crack performance is better than J506.
Should be 506 electrodes bar, J507 is DC alkaline welding rod, and J506 is AC and DC dual basic electrode.Their selection depends mainly on the welding properties, if welding welding seam is important, the general should use J507 electrode; if the weld is not high, is connected to weld, then select the J506 electrode.In addition, if only the AC power supply, you can only choose J506 electrode.In short, under normal circumstances, the basic electrode should try to choose the DC power supply electrode, because it tends to be less than the gas and DC welding electrode.
507 506 welding preferred 506. No 560 electrodes, this specification, model, brand.Brand: J506, model: E5016 belongs to low hydrogen and potassium alloy structural steel welding rod. AC welder (no-load voltage is not lower than 70V, machine load rate of not less than 60% of rated output current, welding welding not less than 300 Amperes) DC welder (reverse connection wire clamp is connected with the cathode electrode holder is connected with the anode -, +) polarity electrode. Good welding process. Non Q345 class boilers, containers, pipes and other special components; first choice should be J506 welding rod.Brand: J507, model: E5015 belongs to low hydrogen sodium type low alloy structural steel welding rod. The electrode does not contain arc stabilizer. Only reverse polarity welding shall be used. Suitable for welding Q345R, container, steel and other precision parts. Compared with J506, the deposited metal has lower porosity, slag inclusion, crack and so on. It shall not be used without DC welder.
