Applications

It is relatively insensitive to rust and dirt on a base metal, and makes better resistance to pockmark
and pits. As the consumption of flux is low, it is very economical.

Notes on Usage

Characteristics on Usage

AWS A5.23/ASME SFA5.23 F8A4-EG-G is a basic agglomerated, slightly Si-alloying flux for submerged arc welding, specially for single and multi-pass butt welding of mild, medium and high tensile steels.It provides good bead appearance, better slag removal and high impact value of the weld metal together.

It is relatively insensitive to rust and dirt on a base metal, and makes better resistance to pockmark
and pits. As the consumption of flux is low, it is very economical.

① Dry the flux at 300~350°C (572~662°F ) for 60 minutes before use.
② When the flux height is excessive, poor bead appearance may occur.
③ Use welding current and speed as low as possible at the first layer of groove to avoid cracking.
