Specifications
AWS A5.18 Class ER70S-6
Description
S6 contains high levels of manganese and silicon for stronger deoxidizing power where stringent cleaning
procedures are not possible. This wire has been designed to provide X-ray quality porosity-free welds and the
highest tensile strength (as welded) of the plain carbon steel wires. The high silicon content increases the fluidity of
the weld pool, creating a smoother bead appearance and resulting in minimal post-weld grinding. S6 is excellent
where poor fit-ups or rusty and oily plates may be used.
Applications
Construction work, tanks, truck bodies, farm implements, pipes, steel castings or forgings, shaft build-ups and
general shop fabrications.
