What I have done in the past is what we called a "Button Weld Metal Test".
This is where we would have the welders burn half to a complete rod (or Electrode) in a one inch diameter puddle. Then let it cool for a minute or five. Clean slag (if applicable) and lay down another rod on top of that. This was to ensure that we had as pure of weld metal deposit as reasonably possible that was not diluted /adulterated by base metal. Then PMI that "button" of weld metal.
If memory serves me, there was a Spread sheet made up that recorded all these tests and was entered in the "Job Book".
Acceptance criteria was that the resultant chemistry met the manufacturer's claim.
