1, neutral flux
Neutral refers flux after soldering. Deposited metal chemical composition and chemical composition of the wire does not produce significant changes in the flux. Neutral flux for multi-pass welding. Particularly suitable for welding the base metal thickness is greater than 25mm,.
2, active flux
Flux refers to the addition of small amounts of the active Mn, Si deoxidizer flux. Can improve the anti-hole and anti-crack ability.
Active Flux has the following features
3, alloy flux
Alloy solder alloy components add more for the transition of alloying elements, the majority of sintered alloy solder flux. Solder alloy is mainly used for low-alloy steel and hardfacing welding.
4, smelting flux
Fused flux is after various mineral raw materials according to a given mixing ratio, heated to 1300 degrees, stirring evenly baked after melting, and then quenched in water to make the granulation. Then after drying, crushing, screening, packaging use. Domestic brands smelting flux using "HJ" said its content behind the first digit indicates MnO, the second digit indicates the content of SiO2 and CaF2, the third digit of different brands of the same type of flux.
5, sintered flux
After given in accordance with the proportion of mixed dry ingredients, then add binder (water glass) were wet-mixed, and then pelletized, and then into a drying oven curing, drying, and finally by about 500 degrees sintering. Domestic sintered flux grades with "SJ" said subsequent first digit indicates the slag system, the second and third digits indicate the different grades of the same flux slag system. a, where the flux is substantially free SiO2, MnO, FeO, etc oxides. b, little flux on weld metal oxidation. c, severe oxidation duri
