Hi Kevin,
It's the first one I posted... why? Think about it for a minute and ask yourself this... AWS D1.1 is a structural welding code - correct? So understanding ths, it makes sense to presume that we are talking about a structural joint as opposed to a pipe/tube joint whereby some medium, whether it be gas, liquid, or even slurry is being transmitted through the pipe/tube and into the adjoining pipe/tube which would then call for the need of having a hole on the main pipe/tube in order for the medium to be transmitted from one pipe/tube to the adjoining pipe/tube...
Now that we clarified what the intended service is for the joint in question, we can presume this: It should be that one tube (Tube 1) jointing another main tube(Tube 2) without the main tube having matching hole cut, right? - would be correct - unless of course there a note in the contract drawing(s) indicating with a detailed drawing showing the hole from one view that includes a center line going through the main tube starting from the axis of the other tube... There would also be hidden line representing the edge of the hole on the drawing and clearly indicating that a hole is to be cut prior to joining the 2 tubes together...
I mean it doesn't make sense to cut the hole out afterwards if the intent is to transmit some sort of medium through one tube into the tube that it's joined to...
Clear as mud eh? Oh well, eventually you'll figure it out.. It's busy morning for me so I got to run.
Respectfully,
Henry
