AWS ER70S-6

AWS ER70S-6

A copper-coated, mild steel solid welding wire that is formulated with a high deoxidizer content to provide excellent welding performance with CO2 and argon rich shielding gases. The produces an exceptionally smooth and stable arc with minimal spatter and offers good wetting characteristics that allow for uniform tie-in.

TYPICAL MECHANICAL PROPERTIES* (As Welded)

• Maintaining a proper welding procedure - including pre-heat and interpass temperatures - may be critical
depending on the type and thickness of steel being welded.
• For out of position welding, short circuit or pulsed spray transfer modes must be used.
• See Above: The information above was determined by welding using 75% Ar/25% CO2 shielding gas with a flow rate between 25-50 cfh (14-24 l/min).
• Pulse waveforms are designed with nominal operating points that may result in average voltage and current values that differ from the above
table. Generally, pulse processes can be expected to produce lower heat inputs than a standard CV process.
