OK submerged arc welding flux is available with Flux Pack™ packaging, which uses heavy-duty LDPE (low-density polyethylene) material to protect dry agglomerated welding flux against moisture re-absorption from atmosphere. Packaging, by affording extended shelf life, ensures fresh and dry flux is ready to use for high-production SAW applications. Net weight of flux packaging is 50 lb, which helps meet EHS and ergonomic requirements of end users.
