copper coated electrode in steel weld

what happens to copper when copper coated electrode is used  ???? if copper has zero solubility in steel how it works as austenite stabilizer
Reply:My understanding was that the thin film of copper has two jobs:1. Prevent corrosion (rust) on the steel wire during storage2. Improve electrical conductivity during the weld processThe little copper that is left has floated out and is usually cleaned off before a perminant protective coating is applied.Be wary of The Numbers: Figures don't lie,. but liars can figure.Welders:2008 Lincoln 140 GMAW&FCAW2012 HF 165 'toy' GTAW&SMAW1970's Cobbled together O/A

Reply:This is a guess but thinking the copper it so thin and melts at a lower temp wouldn't most of it get flash vaporized as the arc melted the rod ?
Reply:Copper is used as an alloying element in steel, not just a coating."USMCPOP" First-born son: KIA  Iraq 1/26/05Syncrowave 250 w/ Coolmate 3Dialarc 250, Idealarc 250SP-175 +Firepower TIG 160S (gave the TA 161 STL to the son)Lincwelder AC180C (1952)Victor & Smith O/A torchesMiller spot welder
