Shielded metal arc welding of general heavy structural steels for ships, buildings, bridges and
pressure vessels made of mild steel. For welding of heavy-duty structures and heavy plates.
Characteristics on usage
LB-26 is a low hydrogen type covered electrode containing iron powder in its coating so that
the welding efficiency can be improved.
The weld metal provides good X-ray soundness and mechanical properties.
The welding in all positions can be easily done with the good usability of stable arc, good
slag removability and good bead appearance.
Notes on usage
Dry the electrodes at 300-350°C for 30-60 minutes before use.
Take the back step method or strike the arc on a small steel plate prepared to prevent
blowholes at the arc starting.
Keep the arc as short as possible.
