It just means one more rifle in that caliber. Which is never a bad thing.

Throw a backing block in there and filling the gaps wont be a problem. just gotta be careful with the heat input. mig would be the way to go with anything over a 1/4" gap. fill it, grind it down and see if there is any defects. Jay, let me know when you get the receiver parts in.

Go mig make sure you have the right wire for the application. Take your time make sure everything is straight. MAKE SURE EVERYTHING IS STRAIGHT. With a mig you can stop if it gets hot and pick up where you left off. No slag. I wouldn't suggest using cheap flux core.
Flux core is used in heavy industry to crnk up and go high deposition very fast. You want a solid weld I think the pressure the reciever takes on is like 40000 psi maybe more. Re welds are alot of work but worth it.

Kc and kevin i will let you guys know what I end up with on weds night. I think between the 3 of us we can get this worked out.

I had one of those HF 90 amps. Good machine for the price, but way too much slag from the flux core wire would be deposited on the lugs to make a functional rifle. Wait until you buy a shielded machine, they make much cleaner welds.

[sandeggo]

Not trying to start anything but flux cored wire, when deposited properly, should produce just as clean welds as gas shielded wire. Granted this isn't the ideal application for self shielded wire but it could be done clean and strong. If you saw slag when you ground down your weld, then you were using the wrong technique and produced slag inclusions. Slag inclusions are not a defect produced by the machine or the wire, only the operators technique.

I have to disagree to a minor extent. The machine can make a difference but it will not be noticed until someone has gained a lot of skill. The arc quality on the lesser machines is just not as smooth. Why do you think they are so inexpensive. Once you've gotten some good skills down and welded with a $4K machine going backwards suck. Those high end machines are just to easy to weld with. But you get what you pay for.
Don't get me wrong they will get the job done. but are just not ideal for certain applications.
What really makes a difference outside of the operator is quality wire and you can't buy quality wire in small spools. Lincoln NR 211 is a structural steel self shielding wire but only comes in 40# spools that I've ever been able to find.
I have a spool but it's .040" diameter a little heavy for something like this. I doubt the little HF machine could even run it.
Like I said we'll figure something out.
I've got a full bottle of steel mix if one of those welders has a port to plug in a line. I can wire a solenoid in.

I teach welding at 2 different community colleges so I know what you're talking about. I have welded with those machines and $7k welders. Basically what I'm saying is that without experience it can't be done. I would put an incredibly huge wager on it that I'd be able to do it just fine with the flux cored wire. I actually have a cert to do it haha. I have a Lincoln 110 that is setup for c-25 that would work perfect for this build. .030" wire and has a nice smooth arc.

I welded a Galil with a HF Fluxcore and it works great YMMV. Looks tits too.

Ok guys so I got the receivers in today. All of the polish AK receivers are pretty much toast. 4 out of 5 are cut thru the threaded barrel area up front and I doubt they can be fixed (maybe, but I don't think they can). 1 of the 5 is cut up thru the area where the rear sight bock meets the receiver and may be able to be fixed.

As for the Galil Receivers, 5/5 are all serviceable and can be rewelded. the gaps are not to huge to fill and they can be done. I will post pictures when I get a chance.

Is that an AWS D7.62 or D5.56??

At this rate I think the Galil's are going to the highest bidder.

I'm still Down for this with a Fully equipped shop and a 200 amp Tig machine. Tools in the garage beer in the fridge

[Jayruta]

Anyone have Galil receiver dimensions, a CNC Warrior Galil Receiver, or a Galil in San Diego that I can take measurements off of?
