Dear all
Thanks for the help.
We're using a non-plated wire to prevent copper inclusions.
If I can't find an easy chemical test for copper contaminations (spectrometry is too expensive) we'll try the ceramic backings.

Dear Forum
We're doing gas metal arc welding of structural steel parts with copper backing and fear that we get copper into the weld. I'm looking for a chemical spot test to find copper contamination in the welds. Does anybody know about such a test?
Any help is highly appreciated.
Michael
