thought some folks here might be interested in this
nice link, cheers, I’m actually going to be doing this in work in the future as companies are trying to move from copper pipe work to aluminium to cut costs and metal theft.
Holy crap !
That looks like a much better product than the old green sticks - thanks for sharing.
seems good for fill work, but maybe not joining parts. I suppose you could tin both parts, the set them together and heat
he had a square tube with various other tubes welded to it, seemed to do the trick there.
I have that stuff and have used it. It's great! To join two parts you do need to "tin" both sides then reheat to fix them other wise it won't work.
Johnny, do you remember where you got it?
There seems to be several similar ‘no flux’ products, durafix, wizardweld, ats2000, and i can’t decide what to try.
also found muggyweld super alloy 1 (350F) and super alloy 5 (600F). both use flux and are considerably more expensive than the other products…
I have fixed holes and stress cracks in aluminum boats several times with those rods and ones from other manufacturers. It's not as easy as it looks, but with practice, it does the job and it holds up well.
- what did you use for flux when joining two pieces together?
There is no flux with most of these rods, everything needed is already in the filler metal. It does have to be clean, though - meaning no oxide layer on the workpiece and no grease, not even what comes off your fingers when clean, so stainless brush (that's ONLY ever been used on aluminum, and never on steel of any flavor) and then acetone wipedown. Same prep work as with TIG.
Wow thanks for sharing.
I have never seen this, looks really easy in the video.
Since I have seen this I am thinking hardly thinking about what I need to solder with this…?
What do you mean by metal theft?
copper is very valuable to weigh in as scrap, whole installs can be ripped out for the copper as well as warehouses being broken into to steal it, substations get broken into to steal the copper bus bars etc.
Whilst its nice to think of the scum getting burnt by liquid refrigerant, it unfortunately doesn’t happen to them often enough.
I got mine at Harbor Freight
Awesone, thanks dthrckt.
