OK Flux 10.90

SAW. Wire, Strip & Flux in Standard & Bulk Sizes

OK Autrod submerged arc wire, strip, and flux are available in high-volume grades and sold in larger volumes for better weld economy. Wires come in both standard spool sizes and ESAB's unqiue Marathon Pac bulk wire drum for reduced downtime, process stability, and efficient handling. OK Autrod is ideal for high-volume production, and manufactured in our Vamberk Center of Excellence in the Czech Republic.

SAW Flux that Helps You Save

Electroslag welding is similar to submerged arc strip cladding. The difference, however, is in the flux. ESW flux provides increased speed and fewer cladding layers (weld deposit), resulting in an overall lower cost of operation. Savings are in consumable costs and fewer man hours required.
