Submerge Wire & Flux (Sorex Brand) – SF-30x SW-308/308L
SF-30 Submerge Wire | High Deposition SAW Wire
In heavy structural engineering, shipbuilding, and pressure vessel manufacturing, choosing a reliable submerge wire is essential for maintaining weld integrity and high productivity. The Thermatech SF-30 Submerge Wire (AWS A5.17 / Submerged Arc Welding Wire) is engineered to deliver high deposition rates, deep joint penetration, and superior mechanical properties under high-amperage continuous welding conditions.
Each spool of SF-30 submerge wire is coated with a uniform copper layer that protects against atmospheric oxidation during storage while ensuring smooth electrical transfer through contact tips. When paired with suitable agglomerated or fused welding fluxes, SF-30 produces dense, pore-free weld deposits with smooth surface contours and self-releasing slag. Designed for automatic and semi-automatic SAW equipment, it provides exceptional crack resistance and consistent radiographical soundness on heavy H-beams, box girders, wind towers, and heavy wall piping.
DESCRIPTION :
SF-30 is an agglomerated flux adding proper contents of alloying element to maintain the stability
of the contents of ferrite in weld metal. It is designed for welding with stainless steel 308/308L to gain
characteristics of great crack and corrosion resistibility and mechanical property, but also good weldability
involved excellent slag removal, stable arc, smooth bead appearance and welding efficiency.
APPLICATIONS :
It is applied in submerged arc welding with stainless steel 308/308L.
NOTE ON USAGE :
- Use of low heat input to get the corrosion resistibility and mechanical properties on heat-affected zone.
- Rebake flux at 350°C for 1hours after opening use

Technical Advantages of Thermatech SF-30 Submerge Wire
Built for high-volume automated fabrication lines, our submerge wire provides key operational benefits:
- Superior Arc Stability & Low Tip Wear: Uniform copper plating minimizes friction inside wire feeding systems and reduces wear on copper contact tips during long continuous welding cycles.
- Radiographic Quality Weld Metal: Balanced Manganese ($Mn$) and Silicon ($Si$) chemistry deoxidizes the weld pool, eliminating gas entrapment and passing rigorous non-destructive X-ray tests.
- High Travel Speed Efficiency: Excellent puddle fluidity allows higher travel speeds without undercut or bead distortion, lowering labor costs per meter of weld.
- Easy Slag Removal: Produces smooth bead geometry beneath the flux blanket, allowing slag to detach easily for fast multi-pass weld preparation.

FAQ: Frequently Asked Questions About SF-30 Submerge Wire
Q: What primary industrial applications require the use of SF-30 submerge wire?
A: SF-30 submerge wire is designed for heavy-duty industrial fabrications, including structural H-beams, box girders, pressure vessels, offshore platforms, ship hulls, and large-diameter oil and gas pipelines that demand high deposition rates and deep penetration.
Q: Why is submerged arc welding (SAW) with submerge wire more efficient than MIG welding for thick plates?
A: Because the arc is completely buried beneath a blanket of granular flux, heat loss to the atmosphere is virtually eliminated. This allows the process to utilize much higher welding currents (amps), resulting in significantly higher deposition rates, deeper penetration, zero spatter, and faster completion times on thick steel plates compared to standard MIG processes.
