Superior SAW Wire and Flux Solutions for Submerged Arc Welding Excellence
D & H India is a trusted manufacturer of high-efficiency SAW Wire and Flux systems. Engineered for deep penetration and high deposition rates, our solutions deliver unmatched performance for heavy-duty welding operations across the globe.
What is SAW Wire and Flux?
Submerged Arc Welding (SAW) is a high-productivity process where a continuous consumable wire is fed into the joint while a granular flux covers the arc. This protective flux layer prevents atmospheric contamination and stabilizes the arc, ensuring clean, high-integrity welds.
Our SAW Wire and Flux combinations are meticulously matched to offer optimized metallurgical properties, excellent arc stability, and minimal slag for seamless industrial output.
Why Choose D & H India?
- Excellent Bead Appearance: Produces smooth, uniform welds with minimal spatter.
- High Deposition Efficiency: Faster welding speeds for high-volume productivity.
- Low Weld Defects: Advanced flux formulation controls impurities and stabilizes the arc.
- Versatile Compatibility: Ideal for both automated and semi-automatic systems.
- Precision Pairing: Guaranteed performance through matched wire-flux combinations.
SAW Welding Flux Specifications
Type & Grain Size
Available in fused, bonded, or agglomerated types. Our grain size is controlled (0.2 mm to 2.0 mm) for proper feeding and slag coverage.
