Type : Neutral
Industry :
AWS : A5.17/ASME SFA5.17 F7A(P)8-EH12K
JIS :
EN : ISO 14174 S A AB 1 / 14171 S3Si
Applications
Multi-layer welding of various kinds of structure such as ship buildings, offshore structures, machinery, pressure vessels, large diameter and heavy wall steel pipe.
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.
Notes on Usage
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 Use welding current and speed as low as possible at the first layer of groove to avoid cracking.
