Purpose
- Aluminate-basic submerged-arc (SAW) flux, basicity 2.1 — high-speed multi-pass and tandem welding of spiral pipe and high-strength steel.
Why it works
Higher current-carrying capacity than the general-purpose FERVEO FLX PIPE allows welding at higher tandem speed — built for spiral-pipe manufacturing lines where throughput matters as much as joint quality.
Fields of application
- Spiral pipe manufacturing, multi-pass and tandem welding, high-strength steel.

Advantages
- High current-carrying capacity for higher welding speed.
- Excellent weld-bead surface finish.
Limitations
- Built for high-speed tandem welding on pipe-mill lines — for standard-speed general fabrication, FERVEO FLX BAS/BFB are the simpler choice.
