SJ101Q
Product Description:
Fluorine-type high alkalinity sintered flux, alkalinity is about 2.0, flux is round particle size of 10 ~ 40 mesh, loose loading ratio: 1.2-1.25g/cm3. It has excellent welding process performance, stable arc combustion, excellent slag removal performance in groove, beautiful welding forming, and high low temperature impact toughness of deposited metal. Suitable for DC welding, welding wire to the positive electrode.
Meet the standard:
AWS A5.17 F7A4-EH14
AWS A5.17 F7A4-EG
NB/T47018-2017
Scope of application:
The flux is a special flux for welding bridge steel, and with appropriate welding wire, it can weld a variety of low alloy bridge steel, ship, wind tower wind power welding, pressure vessel steel.
Welding position:
Flat fillet welding
Note:
Prior to soldering, the flux must be baked at approximately 300-350 ° C (572-662 ° F) for 2 hours.
Before welding, it is necessary to remove rust, scale, primer and other impurities on the surface of the base metal to obtain excellent welding deposited metal.
In the case of multi-layer welding, the bottom welding of groove welding requires a small current and welding speed.
New flux is added regularly to prevent flux defects and poor bead surface forming caused by flux reuse.
