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.
