illustrate:
SJ102GX it is a special sintering flux for fluorine-alkali type pipeline steel, with a particle size of 10 ~40head. SJ102GX it has excellent welding process performance, stable arc combustion, beautiful welding seam shape, easy slag removal, and excellent low-temperature impact toughness and crack resistance of the welding seam.
use:
mainly used for X80 submerged arc welding of pipeline steel can also be used for the welding of other high-strength and high-toughness steels, such as WPHY80 steel.

deposited metal X radiographic inspection requirements: I class
sulfur and phosphorus content requirements of flux:
1.sulfur content of flux ≤ 0.030%
2.phosphorus content of flux ≤ 0.040%
things to note:
1.flux must be 300-350 before use ºCbake for 1-2 hours. the welding wire should be dry, oil-free, and rust-free before use.
2.the welding joint must be thoroughly cleaned of oil, rust, moisture and other surface impurities.
3.dc reverse polarity welding is used, and the welding wire is connected to the positive electrode. 4. due to the welding method, the fracture form has a certain impact on the performance of the weld metal. the above welding methods, conditions and extremely standardized suggestions are for reference only. users should conduct process evaluation based on their own welding characteristics before using the welding wire for formal product welding.
