UNIBRAZE Mild Steel Welding Wire AWS A5.18 Class ER70S-6. 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 increase 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. Approved to CSA ER49S-6 and CWB approved. Shop welding products.
