Bonded Fluxes
Bonded fluxes are manufactured by dry mixing the ingredients and gluing them together with a liquid binder, such as sodium silicate. The particles are then baked and sieved to achieve the desired flux particle size. Generally one grain size is offered, which operates over a wide variety of current ranges.
Bonded Flux Features:
- Contain metallic deoxidizers
- May contain alloying agents
- Flat, low gloss, or dry particle appearance
- Each flux particle has a unique chemistry.
BondedFlux Benefits:
- Presence of deoxidizers provides good performance over rust and mill scale and helps prevent weld porosity.
- Usually provides better peeling properties than fused fluxes.
- Alloying elements can be added to provide improved chemical and mechanical properties.
- Usually exhibit lower flux consumption than a fused flux welded at the same current and voltage.
