The combination of MIL-STD-2219, MIL-STD-1595, and AWS D17.1 is the cluster-fuxk of all time. Sorry to say AWS totally missed the boat with their version of D17.1. It is impossible to qualify a welder to D17.1. There is no bend radius listed using D17.1. You are forced to refer to MIL-STD-1595 in order to perform a bend test. The kicker is there is no thread to follow from D17.1 to MIL-STD-1595.
D17.1 was a chance in a lifetime of harmonizing the military welding standards for aerospace application with AWS B2.1 with regards to M numbers, F numbers, etc. Poof! They missed it, the boat has left the dock, the train has left the station, the plane has left, oops, there it is at the end of the runway, nose gear in the mud!

Now don't hold anything back Al.LOL
M.G.
So is the Ti BS that a few codes and standards have come up with also... Al please don't get me started on down that road also!!! ROTFLMFAO!!! :) :) :) :) :)

Yes I agree. Just this morning we had a vendor ask if he could transfer his 1595 certs to a D17.1 callout on one of our drawings.
I double checked both specs just to be sure. While the same tests are used, the acceptance limits may be different. In some cases they are more strict in D17.1 and in some cases more liberal in D17.1. If a qual specimen is clean with no indications a direct transfer is possible, but if there were indications, it would need to be reflected in the paperwork and reviewed against the "new" limits in D17.1. The problem is our QA tech does not record indication sizes on certs. She justs says pass/fail. While we rarely if ever see indications in quals, it puts me in a gray area if I just say transfer with no review of prior data. But, that is exactly what one of our divisions has done. For the next 5 years of so they say they will accept all 1595 certs as equal to D17.1.
I've seen many Codes and Standards that accept qualification transfers from one to the other if and only if you receive the blessing from the customer. It could save a fortune in costs.
A problem is time. Some customers resell the parts I make to a final customer and don't want to risk my being wrong (not being able to ship parts due to no welding procedure).
Another problem is knowledge. Other customers wouldn’t know a bare stainless steel rod from a bare aluminum rod. They don't have the time or capacity to understand my request and insist on a new set of welding documents.
I bring the transfer option to their attention to satisfy my own ethical standards, but make more money with their decision.
