Default Ali brazing...

This is going to sound very numpty, but.....

Planning my special and the design is based on panels with riveted joints.

But the option to "weld" would be nice.

Don't want to spend the £700 or so for a TIG and in any case it's a steep learning curve from what I gather.

Ditto oxy-acet, and it also scares the hell out of me.

But....what about the brazing rods you can use with propane?

I know they don't work with butt joints. But one could either put a joggle in the panel, or even let the panels overlap and cut through both at an acute angle to produce a mini scarf joint.

Any views?

Expect to be shot down, but you never know!

Would have thought propane sheet metal brazing would cause a lot of distortion. Tig is really not that bad, oxy acet is ok but i understand your concerns. I would investigate oxy propylene or mapp gas too.

There’s a guy who demonstrates these brazing rods every year at Autosport in Birmingham and he looks to get good results but I’ve never had occasion to try them as TIG has always been my ‘weapon of choice’.

Generally, an hour or so of googling will help you get to the bottom of what you need to know. As a process for a beginner, I’d see no reason why you couldn’t use it. For more technically challenging projects, TIG or gas welding is going to be your best way forward.

Hope that helps.

Check out the Tinman's website and his videos on YouTube.

Search using "Soldering Aluminum Tinman" and Brazing Aluminum - Tinman"

and, best of all, one of his workshops.

Thorough, logical and scientific.
