E 51 55 Mn B
AWS/ASME SFA-5.1
E 7016-H8
Application / Properties:
Multi-purpose electrode for
assembly work, workshop and
repair welding; also
approved for rail joint
welding. Smooth and clean
weld blending into base
meral without undercut. Good
gap bridging properties.
Owing to its double
covering, electrode has a
stable and concentrated arc
and good suitability for AC
welding. It is specially
suited for root pass and
positinal welding. welds arc
of X-ray quality.
