Not sure, anybody interested?

Is that TIG or MIG? I still have trouble telling at times. Also, what kind of rig do you have?

I have a little MIG welder that I have used on occasion and I've done some Acetylene and stick welding in the past in the past, but never got much chance to do TIG and nothing I'd ever consider to be "professional" much less put on a plane for any of them. Only fixing up a go-cart, lawn mower, or something similar around the house.

CAPflyer, this is oxy/acetylene gas torch aluminum welding, neither TIG nor MIG. Old school style as was prevelant in the days of aircraft and automobile skins. For thin materials, the best and most workable welding technique. In my opinion. Fun to succeed at a challenging task. It just takes the proper process and techniques.

That's even more cool that you're doing it the old school way. Might have to pull out my kit out and work with it again. Doing welding with a torch is definitely more difficult.

Now, who knows of structural adhesives being used back then? One side seems to have witness marks of some but the other side does not.

I came across this print on the 'A' blueprint spool today, and it rang a bell - any possibility this 'tape insulation for dissimilar metals' could have been what was used?

Stainless steel to aluminum joints would need that. Monel rivets might be used then.

[sdennison]

Any steel/aluminum interface got a gasket, especially under nut plates. They were concerned with galvanic corrosion with the salty atmosphere.

Is that something like the zinc chromate putty tape?

Was there spot welding flux or paste used?

Where?

Just wondering about the marks. I'm not aware of any metal to metal adhesives being used back then.

Thanks, neither am I but I always like to look to the WIX brain for other opinions.

Hey, check out this new service from my Friends at Aircorps Aviation. I work with the Corsair drawings they have cleaned up and they are great. You can blow them up without pixelation.

I just got two of these in the mail. They are works of art!! (Of course, I shouldn't be surprised, considering who's making them........)
