GEEFLUX 544

SPECIFICATION : AWS/SFA 5.17 : F7A(P)5

CHARACTERISTICS :

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.

TYPICAL APPLICATION :

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.
