???I really need to see if DC TIG is gonna save the day for this trouble or not - I need to myth bust the internet chatter on this one...
"Some say" Birmabright can be welded with TIG (Argon shielded) - "they" say Birmabright responds better to DC rather than the more commonly used / assumed AC systems used for aluminium.
Definitely the easiest thing to do. Make sure you use aluminium pop rivets otherwise you'll end up with the same trouble again.Think I will stick to pop rivets, there is the odd one on the landy any way .........
Oh yeah that gunk repair shops are now starting to use =>I remember seeing someone repairing the tub and bonding the alloy with some kind of liquid metal paste, it think it worked fine with a few pop rivets for location.
Regarding alloy welding it's a bit specialist, if you have to get it done by a professional I bet you would soon hit the cost of a new wing if they are £60.

Ain't you supposed to reverse polarity for alli so it arcs towards the gun."Some say" Birmabright can be welded with TIG (Argon shielded) - "they" say Birmabright responds better to DC rather than the more commonly used / assumed AC systems used for aluminium.
If DC TIG is a solution new bits could be welded in place where there was once corrosion dust.
I've got a DC TIG amplifier. I've got argon gas. I've got several packets of different electrodes / wolframs to try out. I've got filler rod (can't remember the type I got but it is meant to be good for Birmabright). I've got a load of 5251 aluminium which is meant to be the closest modern version to Birmabright. I've got old Birmabright. I've got Birmabright with holes...
...still haven't gotten around to trying it out yet though...
I've read that too - I'm not sure if it is necessary - but I haven't tried yet - too distracted with other things...Ain't you supposed to reverse polarity for alli so it arcs towards the gun.
Something to do with the arc breaking through the anodising and not mixing it with the weld.I've read that too - I'm not sure if it is necessary - but I haven't tried yet - too distracted with other things...
