.100 thick in 7075. Oh wow.

TIG welding ain't what you're looking for. Good luck with that

Well its a channel with a 6061 block to back it so really I'm looking for someone who can weld a 7075 sheet to a 6061 block.

Aluminum Workshop: Why isn’t 7075 weldable?

Frank Armao explains why some alloys in the 7XXX and 2XXX families are incompatible with fusion welding processes.

There's a reason everyone is saying the same thing.

Can you melt 7075 into 6061? Sure.

Would any real welder stand behind that work? Absolutely not.

Hood886 and 5 57fairlane know WTF they are saying. I'd listen to them intently and take Hood up on his offer to look at it.

They alloy does have a brand name which I do not know, the forgings were produced overseas for Artillerie-Inrichtingen, the Dutch national armory, I have been told that for all intent and purpose it is 7075.

This part is unobtainium, it is not any kind of AR15.

Thanks for your interest.

Is this a Dutch AR10?

As others have said, welding aluminum can be tricky even a same alloy on both parts that is 100% known. Everything has to be perfect (including the wire chosen) if you want something more than a piece of dull Aluminum brittle. It will not be cheap if you want a safe and functioning firearm You've had an offer to look at it. I'd take them up on it.

Go to a car performance shop. They weld aluminum for intakes and turbo piping all the time.

That's not even close to the same thing he's asking to have welded.

This is true. I weld aluminum, steel, and mig braze on vehicles and what the op wants welded is nothing like vehicle alloys.
