Application / Properties:
Basic low hydrogen electrode
that produce crack-free and
tough weld joints in as weld
and heat treated condition
weld meal toughness in CTOD
test at -100C
is very good. This electrode
has smooth and clean weld
blending into base metal
without undercut. It is
specially suited for root
pass and positional welding.
