Shielded metal arc welding of heavy-duty
structures such as ships, buildings, and
machinery made of mild steel. For all-
position welding of heavy-duty structures.
Characteristics on usage
B-17 is an ilmenite type covered electrode, which is designed for better weld ability in
As its crack resistibility, porosity resistibility and X-ray soundness are excellent among
ilmenite type electrodes, structural steels with heavy sections up to 20mm cab be welded
B-17 has been used in the various fields due to its higher reliability since 1942 when it was
Notes on usage
Pay attention not to exceed the range of proper currents. Welding with excessive current not
only lower X-ray soundness, but also causes increase of spatter, undercut and insufficient
Dry the electrodes at 70-100° C for 30-60 minutes before use. Excessive moisture absorption
lower usability and may result in some porosities.
Excessive drying before use causes less penetration and overheating of the electrode.
Medium or heavy thick plate should be welded under proper preheating and interpass
