welding MIL-DTL-46100E to A36

The welder qualification test may have nothing to do with the actual production welding requirements. The welder qualification test only requires the welder to demonstrate the ability to deposit a sound weld.

I have no experience with MIL materials.
However, from what you say, I imagine a ground combat vehicle made of MIL high hardness steel with some reinforcements, or stiffeners, made of A36 angle iron.
Caution, this is only imagination.

Hey Bruce,
There isn't a structural correlation with TACOM's Code. The design requirements, that you would normally see in AWS Welding Codes, were intentionally omitted from the Code. TACOM relies on the Contractor's design house's personnel and processes for design and development.

If you talking about 12479550 it has a non critial welds, critical welds and ballistic welds. The non critical and the critical say that you can used AWS D1.1 as a applicable reference,but the ballistic welds don't. That's the way I see it.

Hey Milton,
12479550 states that it is to be used in conjunction with appropriate complementary codes or specifications for materials design and construction. So for structural attachments.....if you want to use D1.1, go ahead. Critical/non-critical welds only applies to the inspection/acceptance requirements (not how you should design the welded connection).
TACOM in the end has overall approval.

Tyrone,when we work on a job that calls for TACOM 12479550 we usually have a print that calls out for that code there is no design. Tyrone we did our on PQR,WPS and used D1.1,D1.2,D17.1 and D1.6 if they do there on testing wouldn't that be good enough if it was acceped.

Milton,
Now I understand where you are coming from. I'm assuming you supply parts designed by the Customer (BAE, Northrup, General Dynamics, etc).

Yep, it's good enough if your Customer accepted the PQR, WPS. In turn, your Customer takes full responsibility for your part meeting their design intent (and TACOM's requirements). TACOM's folks are really only focused on armour weldments, but will get involved in structural parts/attachments if quality goes really bad. Then they may show up at your door looking for documentation...

If you do the work by the book and have follow all of the criterior of the print and have all the documentation of the NDT you should be alright.
