Thread: Welding/Soldering Aluminium

A few years ago I saw a bloke a local show day with very similar stuff ,but made in Australia.
He was welding coke cans and boat propellers together......I was impressed and purchased some rods.
I works great .but the filler rod tends to be a different colour from the parent alloys.
Great stuff , it just follows the heat and is a bit like brazing.
The bloke was based at Talraga , just north of Goulburn NSW.
The secret is the alloy mixture of the filler rod.
I find this stuff is as strong as MIG and almost as good as TIG

Ive used something similar, I dont know if its the same stuff but I found that its great for stuff that doesnt "shake" alot. It held a chunk of gear casing in place on an old ride on lawn mower but it let go when I used it to repair a crack in a landies body work.... (to be fair tho the body repair was a year or more after I got the rods so they may age poorly)

It looked good so I bought a beginner pack of rods and since then have experimented a fair bit and even made a frame to mount a solar panel on the roof rack out of some 40mm aluminium angle.

Am very impressed with this product and would recommend that you try it if you have some aluminium or alloy derivative that needs gluing. It's a lot like soldering. You just need to use the correct heat source to get the right temperature for the pieces being worked on.

The torch I used for the panel frame was a normal hand held jobby running off an LPG BBQ gas bottle. It was OK for the small joins but for the big stuff I think a hotter torch would be required and am dreaming of a getting an MAP unit one day soon.

Anyway thought I should pass this on in case someone out there needs to repair something.

Cheers

Hey mate;

any chance you could post up a pic of the aluminum frame you made?

I also got a sample pack at a trade show, and I tried it on a refrigerator evaporator (the cold bit inside the fridge) the owner (female) had tried to assist defrosting it with a carvers fork (ie two big prongs) and stuck one of the prongs right into it.

Well normally you would throw away the fridge - as the cost of repairs just out balances the cost of a new fridge.

5 or 6 years later - the fridge - now my beer fridge still works, the repair hasn't beed affected by ice build up on the outside or refrigerant gas in the evaporator.

..............but as said above the temperature of the heat source is quite critical , fortunately I had practiced on a a few holes in redundant evaporators prior to the real thing.

Is this the American bloke?

I have seen him around and at one stage was going to buy some, but after watching how rude he was to the paying customer in front of me I thought better of it...

I have some of those rods lying around somewhere, tried to repair a crack in a 2dr rangie guard, they are very hard to use as you need to heat the alloy to be repaired so much till the rod melts on contact- tends to bugger the area being repaired.
