The Central Management Team has a problem with us welding zinc-coated(galvanized) uni-strut to structural steel tubing(P1). "Do we have a procedure?", he asks, knowing full well we don't as our procedures have all been approved by the Owner. My copy of W59-03(CSA Metal Arc Welding) does not cover this topic, from what I have researched. Common practice in my experience has been to grind off the zinc then weld it out. Might have helped our cause if the welder hadn't welded right through the zinc. Can someone point me in the right direction(ie. CODE), please?
