thats why when your finished you heat it mildly with Oxy/Acetylene.

Whether the joint would be strong or not - I think that welding just in general for this project is not really the route I want to be going down. Especially as I don't have the kit I would need for it at the moment, and to get a guy to do it for me would be taking some of the 'I did it myself' kind of aspect away from this project, along with costing an arm and a leg! so in my eyes the much cheaper method of brazing joints would be the way forward.

What kind of kit do you have?

Blowtorch, (can get metals hot enough for pretty much most brazing) and clamps etc for holding things in place, but that's pretty much it.

Ideally you would need oxy/fuel for brazing aluminium, you could pick up a cheap tig welder from ebay and a gas cylinder as you can weld and braze with a tig torch.

id say go for it then fill it with water and pressurize it to double your working pressure.
