AWS A5.18 ER70S-2

ASME SFA 5.18 ER70S-2

ER70S-2 is a multiple deoxidized wire containing small amounts of zirconium, titanium and aluminum in addition

to the manganese and silicon deoxidizers characteristic of the steel wire group. This wire may be used

for MIG or TIG welding on all grades of mild and carbon steels, producing superior quality welds with

minimal porosity even

over rust and mill scale. ER70S-2 is popular for out of position welding with small diameter wires

utilizing the short-circuiting arc type transfer. MIG welding may he accomplished

using CO2, Argon-Oxygen mixtures or mixtures of the two.
