Geeflux-544 is an agglomerated basic flux for submerged arc welding. It is used for single and multi-run welding of all plate thickness.
It works equally well with DC & AC current. The good slag detachability & limited alloying of Si & Mn makes it well suited for multi bias thick section welding. High Welding speed can be achieved producing a finely rippled weld metal, all this in combination with very good impact value.
Damp flux must be redried at 300-3500C.
IT's one of the most used SAW Flux, not just for structural steels & fine grained steels, but also for weather resistant steels e.g. for bridges.
