Submerged Arc Welding (SAW) Wires & Fluxes
Submerged Arc Welding (SAW) is used in shipbuilding, pipelines, pressure vessels, offshore, structural steel, and heavy fabrication.
SAW uses a continuous solid wire electrode + granular flux, producing deep penetration, smooth bead, and excellent mechanical properties.

10. SAW Flux Types
Flux is equally important as wire. Selection affects weld chemistry, toughness, slag detachability, and bead shape.
- Flux Classification:
- Fused Fluxes (FF): Non-hygroscopic, stable, reusable.
- Agglomerated Fluxes (AF): Alloyed, basic, good toughness.
- AWS Classification Examples:
- F7A0 / F7P0 → Neutral fluxes (general use).
- F7A2 / F7P2 → Basic fluxes (better toughness, offshore).
- F8A2-B2 → For Cr-Mo steels.
- F8A4 / F8P4 → For high-strength steels.
- F8A6 → Ultra-high strength.
- F7A2-Ni1 / Ni2 → For cryogenic steels.
