Thread: Aluminium Welding Brazing and Soldering with a Hand Held Torch

seems to work okay with low pressure oxy /acetylene equipment

Cobra Torches | Oxy / Acetylene Welding and Cutting System

Have used a similar product called Alumiweld with some success. Good for fixes, holes and single joins. Given how it has a low melt point, if you try to make more than one join, say in a series of pieces, any previous joins if they are close are easily affected and usually melt apart. But, as I said, the one join or fix, the material is really strong. Fixed an aluminium motorbike ramp years ago (after the person I loaned it to misjudged things and a heavy bike broke one side) but its still strong. So yes it works - if you don't have Oxy, works best with Mapp gas, but if you have time ordinary gas will work.

I have a friend who is a highly skilled fabricator and welder. He makes his living from making and welding aluminium and stainless steel items. He says this stuff is a soldering process and not a true weld. He reckons from observation that it is a showtime gimmick intended to remove some of the wealth from the unwary.

You can successfully weld aluminium with oxy-acetylene. Needs practice, a steady hand and good eyesight. I no longer have the latter or time for the first so I get my mate to tig or mig anything unusual that needs proper professional welding.
