Thanks Lawrence,
We are welding rectangular tube, 5052, 2"X3" (.125 WA).
The load strength is still up for question, I will request that from our engineering team, the weld callouts are just fillet symbols, with zero additional joint type detail.
It will be used in a Clean Room environment, so corrosion will not be an issue. I beleive there is a post Nickel plating requirment after welding, which is at the request of the customer.
This is really just a situation where we can qualify to the Sec IX code, but I wanted advise on any differences with D1.2 that may change how we go about the qualification.
These are going to be welded via manual GTAW, only because it is highly cosmetic.
