Applications
AWS A5.23/ASME SFA5.23 F8P2-EB2-B2 is Single-layer welding of various kinds of structure such as 1.25%Cr-0.5% heat resistant steels used for boilers.
Notes on Usage
Characteristics on Usage
Especially insensitive to oil, rust, scale, and dirt on the surface to be welded. It produces the weld
metal which has excellent impact value at low temperature service.
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.
④ Preheat the thick plate according to rules if it has heavy restricted stress.
