D1.3 Tips

[Aircamperace]

I started learning how to weld so I can someday TIG an aircraft fuselage out of 4130 thin wall tubing. D1.3 is as far as I know, the closest thing to this type of welding.

How much does certifying cost? Would I want to certify in all positions? Can anyone offer any advice?

Thanks,

well your are going to need a WPS to certify too first

I might recommend you take a look at AWS B2.1-22-015 10-18ga aluminum with 4043 filler.

Where are you located? You specified the D1.3, which is a code book for sheet steel. What you need is an air-frame class. But if you want to learn aluminum tig, get a machine and practice.
I suggest something like a good inverter. The Dynasty 200 DX, for example, because aluminum just sucks the life out of lesser machines. I would consider the 200 DX an aluminum capable machine for those who are serious about doing aluminum tig. Until you have skill at tig, the machine will offset your inexperience, and you won't outgrow it in 6 months. I bought a used Econotig a few years back, and I won't get rid of it until I get a better machine, but at school I get to use the best.

I am not sure why you want to be "certified" to weld up a fuselage for what I am assuming is a piet. You can attend classes just for aircraft welding on materials like 4130 and other "antiques". If you want to learn thats one thing, but certification??? Maybe you can clue me in more as to why you think you need certification, and what you think being certified actually means?

D1.3 sure as hell isn't the appropriate standard for aerospace tubular structures!

D17.1 is as close as you'll get, and even then, any "certifications" (of which there really aren't any) would be otherwise useless.

Pretty much what I was getting at. Certified aircraft or homebuilts dont require any kind of certification for the weldor, and having any kind of certification still doesnt allow the weldor to "sign off" the work.

Yes, what is the reasoning behind getting certified? I know there are a lot of restrictions on people working on aircraft, like mechanics have to have certifications. I would assume that you would need some certifications for welding on aircraft also.

Just something to make sure you know the difference between “certified” and “qualified”.

Certified: you hold a AWS approved welding certification that was completed at an AWS accredited facility and given by a CWI.

Qualification: you had taken a weld test that was inspected and tested to a certain standard and most likely given by a CWI.

The only two ways you could be “certified” in all position is either a 3G and a 4G plate or a 6G pipe. each test would only be good for one weld process and one material. You would need to do it all again if you wanted to do multiple types of materials, ie steel, SS, aluminum.

In this case the FAA ( the governing body on aircraft ) doesnt care about the AWS. Remember the AWS is nothing special, and in itself has no authority on anything, ever. So a "certification" from the AWS for aircraft welding in this case is about as useful as a degree in cycle riding from the local clown college.
