Applications
AWS A5.17 / ASME SFA5.17 F7A(P)4-EH14 Horizontal welding of oil storage tanks, ships, bridges, pressure vessels, penstocks, boilers and structural steels.
Notes on Usage
Characteristics on Usage
Inactive, neutral type bonded flux which is applicable to all kinds of wire. Impact value of weld
metal and crack resistibility are good. Slag detachability in the groove and resistance to porosity
are good. Usability in horizontal fillet welding and X-ray performance are good.
① Dry the flux at 300~350°C (572~662°F ) for 60 minutes before use.
② Remove rust, scales, oil, paint, water, dirt and slag of tack welds from the groove to obtain
sound weld metal.
③ Use welding current and speed as low as possible at the first layer of groove to avoid cracking.
④ Preheat at 50~100°C (122~212°F) according to base metal and plate thickness.
Keep interpass temperature at 100~250°C (212~482°F ).
