Notes on Usage
Characteristics on Usage
AWS A5.23/ASME SFA5.23 F9A(P)8-EF3-F3 is a fluoride-basic flux with high basicity and low impurity levels such as P and S. As a result of low oxygen levels in the weld deposits uniform mechanical properties with high toughness values at low temperature are achieved. Because of the almost neutral slag-reactions the chemical analysis of the weld metal can be excellently controlled through the selection of appropriate wire electrodes.S-100 is suitable for welding on DC and AC using single and tandem wire processes.
① Dry the flux at 300~350℃ (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.
⑤ Preheat at 100~200℃(212~392℉) and postheat treatment at 605~635℃(1121~1175℉)
