Applications
AWS A5.23/ASME SFA5.23 F8A0-EG-G Single and multi-layer welding of bridges, H-beam and structural steels.
Notes on Usage
Characteristics on Usage
Especially insensitive to oil, rust, scale, dirt and primers on the surface to be welded.
Slag detachability in narrow groove and resistance to porosity are excellent.
Suitable for tandem welding of H-Beam.
As the consumption of flux is low, it is very economical.
① Dry the flux at 300~350℃(572~662℉) 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.
