AWS A5.23/ASME SFA5.23 F8A8-EH14-G Multi-layer welding of high strength steels, such as EH47.
Notes on Usage
Characteristics on Usage
It produces the weld metal which has excellent impact value at low temperature service.Single and multi electrode welding can be performed. It has excellent X-ray characteristics and slag removal, because of insensitivity to rust, scale, primer on the surface to be welded.
① Dry the flux at 300~350℃(572~662℉) 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.
