Hi all, I am new to welding as well as new to forum. I want to ask that ASME BPVC Code section 9 is referred for WPS qualification for fabricating pressure vessels, D1.X for structures, API 1104 for pipelines and many others but what code should be referred for aerospace applications? I am dealing with aluminum alloys and GTAW Process.
Thanx all in advance
waq
I will let
Lawrence take this
one of the best
and always tells me how wrong I am
sincerely,
Kent
Currently drawings refer to MIL-W-22248A.
http://everyspec.com/MIL-SPECS/MIL-SPECS-MIL-W/MIL-W-22248A_3729/Knowing D17.1 today i personally believe that this must be referred for aerospace applications because currently in use 22248A no where states that its for aerospace applications. It addresses only aluminum and its alloy weldments with inert gas shielded processes. BTW, its pretty old as well.
What is your recommendation?
It states that it is still active.
M.G.
For aerospace applications? It no where states so
I didn't say it was for aerospace applications, I said it is still active, if it is called out on a print you will have to use it.

Milt, and Lawrence
are correct
even for the stubborn old man
for me to disagree
need more info
and if this is aerospace
you need an ok from the EOR
and major contractor (might have done business with them....and had a few disagreements
)
sincerely,
Kent
Watch out Waq, the guys are tag teaming you.

3 military standards for aerospace applications were consolidated into Mil-W-2219 in 1988. Those three were MIL-W-8611( Steel), MIL-W-8604( aluminum) and MIL-W-18326( magnesium).
For welder's performance the military standard MIL-STD-1595A.
Now, MIL-W-2219 and MIL-STD-1595 A have been replaced by AWS D 17.1 .
All of the above information is from AWS D 17.1 .
My question is there is no mentioning of MIL-W-22248A anywhere. Had it been related to aerospace applications it would have been definitely mentioned by AWS D 17.1 .
You’re right about all the others being superseded by AWS 17.1 but you’re saying that the (Currently drawings refer to MIL-W-22248A.If you go back to
http://everyspec.com/MIL-SPECS/MIL-SPECS-MIL-W/MIL-W-22248A_3729/ that would tell you if it had been superseded by another code but I didn’t see that anywhere. I might be wrong but you have to comply with what’s called out on the drawing. Sometimes it’s best to have proof that a mil-spec-has been SS/by another code and you need to check for that on ever drawing because they have brought back some of the Mil –STD back like 2219 on occasions.
M.G.
Sometimes engineers cut and copy OLD specifications into a contract.
It might be worth your time to approach the engineer who called out the old specification and ask them if they might actually prefer D17
The military standard referenced, MIL-W-22248A, is for ordinance (things that go bang or boom).
AWS D17.1 is not necessarily the default standard for aerospace applications. MIL-STD-2219 is still in place and applicable when it is specified by the contract drawing. AWS' D17 blew their chance to harmonize D17.1 with other AWS standards. That also left out a major part of MIL-STD-1595, i.e., the required bend radii for guided bend tests. The first editions was useless, so the boys in the Navy charged with aerospace welding revived the cancelled MIL-STD-2219 and made it active. To my knowledge it is still an active military welding standard.
The recent release of D17.1 addressed the omission of the bend radii and a couple of other things, but too little, too late.

You are right sir, MIL-STD-2219 has been replaced with MIL-STD-2219A in 2005 and it is active. Its title is "fusion welding for aerospace applications".
I have the copy of latest version. MIL-STD-2219A refers AWS B2.1 for WPS and AWS D17.1 for WPQ.
It means even an engineering authority invokes MIL-STD-2219A in an engineering drawing we are going to need AWS D17.1.
I found this.
Million thanx to you. You solved my huge problem. But how did you find it? I must check ACTIVATION STATUS of some of the other MIL standards.
I need to check MIL-STD-22248A
Hi all
please also note that aircraft welding is covered by all the "primes" (Aerospace manufacturers) by using Nadcap (formerly NADCAP, the National Aerospace and Defense Contractors Accreditat Program) a global cooperative accreditation program for aerospace engineering, defense and related industries. This makes manufacturers have audits of their systems and processes to ensure they are all working to the same standards.

Mike
