So I had a customer call me with a qualification need. He has a maintenece worker/welder who is about to construct catwalks/platforms in their factory. Before he does the welding the owner wants to qualify the welder to D1.6 using box tube. He wants box tube as this is 99% of what his man welds. This is the first stainless box tube request I've ever had so I did some digging. D1.6 allows prequalified tubular connections so I thought great, this should be easy! Whoa, was I wrong.
Here's the problem. I can't find ANY reference to box tubing, anywhere! Even if I was going to qualify a procedure there are no qualification range tables or diagrams to pull specimens. Everything is either pipe or plate. I suppose we could call pipe, tube....but it's not. And it's certainly not box tube.
Then I thought, forget it, I'll just have him weld pipe or plate. But there is no language about whether pipe or plate qualifies for box tube. I am lost. So, even if you couldn't test on box tube I don't see what test qualifies a welder to weld to box tube.
Do I use pipe ranges and specimen pulls? Do I reference D1.1's box tube ranges and specimens? Am I just overlooking somthing simple? I really hope sombody has dealt with this and can help me out, thanks a ton!
