Interesting Welding Statement.

[AlanB]

Back to the tank, I was there last night looking at it. God I love hanging out in those shops, and asking and learning but am thankful I don't need to be there making my living.

Anyway, what they did on the tank was after the tacks, and everything was in place etc. etc. they went through on the inside and welded DC 6010, then they came outside with a 4.5" grinder, and ground through the tacks and through the joint into the 6010 bead and then welded from the outside with mig, did not look at exactly what they were burning, some big old Airco unit powering one of those industrial driver feeders.

I asked why they did not just do Mig throughout, in and out, and was told that when they do Mig on the tanks like that, you alsways stand the possibility of spattering a bit somewhere as you are running the beads. And anytime you get that pop / spatter when running the bead, you may as well grind it out and go again as it will be sure too leak. (I would agree with that statement) He said with the 6010 they get the nice hot flowing seam in there and it will be water / pressure (fuel I hope) tight and then the Mig topcap is almost insurance.

Should show up here early next week I imagine.

Will grab some pics then.

I had just never heard anyone say that the 7018 would be more malleable than the Mig, there is always something to learn though.

Sounds good, I might have used fluxcore on the outside, good penetration, and slight risk of worm holes. Makes a nice smooth bead. need some pics...

It is so Dark in that shop that my cheapie camera does nothing.

Not sure if they have it out of the shop yet or not for paint.

I can't provide a ton of examples, but I do know that, for example, the 'shoulder' frame on an F-111 swing-wing fighter/bomber was MIG welded by a robot.

Sure.. Many of the frame items have to be welded because you cant make some of those crazy shapes any other way. Life limited items ( mounts and such) are near net forged and then fully machined

Well, they are doing finishing shop touches, and getting ready for paint.

Only 10 years or so from thinking about it too when it will be in the yard working............. How do you eat an elephant

Same way you eat a rabbit........start with the ears.

Quarter turn fasteners, quarter turn fasteners...

What about Dzus fasteners??? Dzus, the ORIGINAL quarter turn fastener used in aircraft and many other applications.

...or we can call them those deally bobbers that hold a panel in place with with only a little turn...

Yep! Dzus is just one company that makes 1/4 turn fasteners.

First to do so I believe and back in the olden days when I was in the USAF, Dzus was to quarter turn fasteners like Kleenex was to facial tissue. It had become the generic term for quarter turn fasteners. Do a good job and you will be copied.
