Aluminium welding rod..
Turbo Mini Forums

I just used some of that aluminium welding rod stuff that is sold on e-bay.. Its an alloy that melts a hundred degrees or so below the melting point of aluminium.

Cleaned the parts with a s/s brush ok, but had trouble getting larger pieces hot enough using propane so used one of those little map-gas/oxygen kits.. It worked quite well. It was quite easy and the end result was presentable... It seems to stick well to the aluminium and seems quite strong.

surely if its melting at a lower temperature (especially by that much) then its not really going to be a very strong join?

good for plugging holes maybe but i wouldnt be "welding" anything together using it, as its just gripping to the two surfaces rather than melting them together.

maybe?

like brazing, just sticks to the surface

there was a bloke at autosport selling this stuff, he demonstrated it to us. he welded 2 squares together with the stuff and you can see it penatrated well. i couldnent even break the weld with pliers, just broke the aluminum. he warmed a bit up on a sheet of alum and it actually burned a hole through.. amazing stuff.

My dad had some of this from a show in the summer, he rates it quite highly. I have tried to break the joint with pliers and the ally sheet breaks first!

frost sell it, it looks shit by the way as i have tried it

I've used that stuff a few times before before with good results, great for repairing cracks in castings if you don't have access to a tig.

used it to patch a cracked astra GTE sump to good effect.

As said above its like brazing I guess, I wouldn't use it for stressed parts. Like a lot of people I saw these things being used to connect coke cans at car shows and didn't rate it but now I have used it I think it has some uses.. As I said above propane is only probably useful on very light alloy, (Coke cans!) for heavier stuff you need something hotter. Like all soldering/brazing the secret is to heat the piece until IT melts the rod, dont just melt the rod with the flame.

Here was my first attempts, not bad.. but I must say better than my first MIG experiments..

Just ran a s/s wire brush over them.... they did flow just like that.

That sounds more like soldering! Brazing and welding require you to localy liquify the parent metals before adding a third to join the two together.

Not good for anything other than light pipe work I would imagine though I am usually wrong.

I seriously doubt it!

Brazing does not liquiefy the parent metal.

Oxy acetylene tourch in one hand brazing rod in the other looking for the eutectic point and quickly feeding the rod into the moulten pool working ones way along the joint.

My explanation earlier may have been overly simplified.

very tide indeed! Tel, nice one!

To braze you just heat the joint til its red then add the rod, it should just flow itself then

I seriously doubt it!

If I was looking to re-join an alloy grill (clubman style) that I had chopped up. Would this be OK with a crappy gas torch?

I need to make a custom grill for my four eyes conversion and was thinking about using this sort of thing to join the chopped up bits together. The welds/braising would be on the back.

i would say this would be perfect!

not a load bearing component, this doesnt really need any specialist machinery, and looks nice and easy to do.

only thing i dont know though, is whether you need an oxy/acet torch or whether the propane one would be good enough for the thickness of the grille?

i've used this. its good!

What did you use to heat it up?

With the grill I've got in mind, I think I only need to chop 4cm out of the way so the join will be fairly well hidden by the badge
