Applications
AWS A5.17 / ASME SFA5.17 F7A(P)8-EH14 Single and multi-layer welding of aluminum-killed steel for low temperature service used in offshore structures, chemical vessels, steel pipes, low temperature service equipments and other structures in cold regions.
Notes on Usage
Characteristics on Usage
Excellent notch toughness at low temperature down to -60°C(-76°F). Suitable for single and multilayer welding of TMCP steel. Resistance to pockmark and porosity is excellent.
Slag detachability in the groove is good.
① Dry the flux at 300~350°C (572~662°F ) for 60 minutes before use.
② In case of multi-layer welding, use welding current and speed as low as possible at the first
layer of groove to avoid cracking.
③ Add new flux periodically to prevent the weld defects and bad bead appearance which occurs
when continuously reusing the flux.
