How do you supposed aluminum was welded before TIG was invented? They
used a torch. It just takes practice.

How long has TIG been around?

He actually prefers to weld aluminum sheet using a torch, instead of
Tig. He sells special goggles for the purpose too.

What alloy and thickness would you recommend to experiment with, simulating
building a tank, and what filler material?

I'm the kind of guy that loves to learn how to do new things, even if I
never use it. ;-)

A tig rig I don't have, but a torch, I do have!

It isn't all that bad, Rich. I use the same Smith torch and tanks for
aluminum as for steel. Use an aluminum flux and soft aluminum filler rod.
I would use a cheap spot welder to tack in the baffles. They work great
on
aluminum.

Better... But certainly not by me.

There was an article in ... I think it was Sport Aviation, or
KitPlanes about a year or so back. The TIG welds looked really good
until you looked at what they did with a torch.


I tried gas welding (or soldering) with a cheap torch with some of that
"miracle rod" quite a few years back before I was interested in building
planes, or really, even welding. The results were horrid. I'll have to

Bout echoes my experience.

give it a try with some proper rod and stock, now that I have a good torch.
What size tip, by the way? (Smith)

You need to talk to da man. Go to http://www.tinmantech.com/ and
ask Kent White your questions. He'll be happy to respond.

His goggles are not cheap, but may be the best in the industry.
