Applications
AWS A5.23 / ASME SFA5.23 F8A4-EA3-G Butt and flat fillet welding of miniature LPG tanks, ships, vehicles, agricultural implements, machinery, boilers, bridges 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. As the consumption of flux
is low, it is very economical. Applicable to horizontal and flat fillet welding.
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 Remove rust, scales, oil, paint, water, dirt and slag of tack welds from the groove to obtain
sound weld metal.
④ Use welding current and speed as low as possible at the first layer of groove to avoid cracking.
