All-
My apologies for getting so far off track re: my uncle. I honestly =
don't know why I was so affected this Memorial Day.
Since there doesn't seem to be a wealth of knowledge about =
oxy-propane welding, I'll try it on scraps of .016, .025, .032, and .040 =
T-6 and let you know how it turns out. The results will definitely be =
real world, because I've never welded aluminum before. So people don't =
freak out, this is a test, only a test!=20
1. Any special surface prep?
2. What grade rods should I use for the different thicknesses?
3. Do you need an additional flux (What grade) or is it integral =
with the rod?
All input appreciated.

To the best of my recall you need flux and blue lenses for gas welding aluminum. Here is a link where you might get some pointers:

I worked with a guy who would cut thin strips (1/8 wide) off the same sheet to use as filler rod and he would gas weld tacks first then, fluxing both the base metals and the rod.

Ron and all-
Excellent link- I'm putting it in my "Keepers" file. This guy looks like
he enjoys tackling the really tough stuff.
For my projected personal use, aluminum welding is not a priority, thus,
I've made my decision.
Considering 99% of the welding I need to do now and intend to do in the
future is on steel, I'm going with the top of the line 240v AC/DC Lincoln
stick welder (at) $500 list price. I'll experiment with gas aluminum welding
after doing more research on the technique in my (Hah) spare time.
Let me stress that this is purely a personal decision based on my
personal experience. With over 35 years welding steel with basically the
same Lincoln rig, I can turn out a job that pros don't spit on. At over $1K
for a respectable TIG rig, it looks like contracting TIG welds is more cost
effective.
Thanks for all your input.

Bill
