Alumiweld anyone?
This is the first time i tried it in anger, other than practicing on an offcut.
It was a bitch to get to adhere to the casting, but i think thats because the flame on my blowlanp was too big and not heating the metal enough. On
top of that it was 5 degrees in the garage with a slight draught!
Anyone else used it in anger before?

i tried using it with a blow torch and no luck whatsoever, but that was just probably my lack of experience

Likewise - I think you need something hotter than a blowtorch [even with mapp gas].

Its possible to do with a blowtorch (as shown in the picture), it just takes aaaages. It took me about an hour to do the above. A smaller, more
concentrated flame would be better. Like a pencil torch, but more industrial! Oven heating the part helps as well of course!

Its essential that you keep it clean and keep removing the oxide as this forms a barrier

you need to get your casting as hot as possible like the oven first, ally gets rid of the heat very quickly at first until the whole thing is hot,
should work a treat after that.
We sometimes harm up ally bloks with the burning gear before we tig weld.

Is this the stuff you get in rod form - that you just use a blow torch with then? I bought some a while back (but think it went under a different
brand name) but didnt have much luck - although i was trying with quite thick stuff so couldnt get the heat in.
Bought an AC/DC tig instead, the not so cheap option lol.
The rod stuff did look good for light repair work though on thin gauge stuff.

I have used a blow torch successfully on 1.5mm sheet.
You should clean the joint surfaces with a wire brush with stainless steel bristles before heating.

It does work well on thin stuff. I presume that given adequate pre-heating and a decent torch that it would work on heavier stuff.

Yes, i bought it from Stoneleigh as a "Just in case i bottom out or smash my sump" kind of thing. I used it successfully on the 3mm scrap
that i had when i first got the stuff.
You dont need to remove the slag, as it works different to brazing. You heat the metal and the rod and place a 5mm piece on the material, which you
then just "Rub" into the joint with the other thinner rod. It melts the two materials and bonds them together.
Clever stuff really. Its not aluminium rod, its a combination of metals, which melt at a lower temperature to aluminium, which then melts the two
materials.

Richard.
