Aluminum repair ( brazing rods ) ?

[LarryL]

Larry,
Like I said, I wasnt picking at all. More a general question about the welding community at large as to why this technology has slipped away. Used to be common, now it's treated like magic. SO when were you in Osh watching the welding demos, and where was it? The Workshops area?

Although I've been an E.A.A. member for over 30 years, I haven't been to the Oshkosh convention many times. The last time my wife and I were there was in '86, I recall. I've thought about going back on many occasions but the difficulty of finding a place to stay while there as well as the long distance from our home in California to Wisconsin always seems to deter me from going. There are many E.A.A. shows closer to home that we can choose from. It was also difficult to take time off from a solo medical practice like the one I had.

I've seen oxyacetylene welding of aluminum demonstrated on several occasions by one middle aged fellow who had a booth from which he sold aircraft welding supplies. He did not do a lot of demonstrations but if you happened to pass by at the right time, you could catch him doing the welding. He was the one who suggested to me that aircraft tanks should be put together with rivets and then riveting over the heads to make them fuel-tight. I tried his suggestion when attempting to fabricate my next fuel tank but the beads that I placed over the rivet heads leaked. I don't remember what kind of aluminum rivets I used but may have botched the job by using 2024 aluminum rivets.

sleep under your airplane wing...at least thats what we do. You can fly about an hour away and take a shower at a small airport that has a pilots lounge. Unless you have a king air or baron 58, in which case I would take out some seat and stay the night in that.

Hi all, I saw the demo for Alumiweld rods on Utube and was so impressed I contracted the firm as to the price etc, but mostly for the specifications and demo pics.

The Alumiweld people gave me a price of $A54.00 for a pack of 20 X 18" rods, so I ordered some online, just waiting for them to arrive.

I haven't done much alluminium welding, practically hardly any as such, but I've had a number of occasions when Alluminium has been on the cards.

In post #6, Yorkiepap posted a number of photos of the alluminium plate joint and the "testing" procedure to try and destructively test it.

Now I will definately say that if I get the same results with an alluminium project as the results posted in Yorkiepap's #6 post, I will be extremely happy.

So it's not welding....the job determines the means for the end result, same as for steel......you can weld it, braze it, silver solder it or even soft solder it, the end result is the determining factor.
