That's interesting, I should like to weld it if I can, I have a TIG welder
and I gather the trick is to use square wave.
I had wondered if the alloy was something special as I haven't had problems
with other (non Bristol) ally welding.
I did try a couple of small tack welds a couple of years back,
unsuccessfully as they cracked post weld but it was all very hasty and I
probably didn't have the machine or myself set up properly ( I hope).

I used an adhesive from Henkel to bond a repair on my 408. The adhesive
used was one developed for the tunnel TGV trains.
So far so good [eight years]

Forgot to mention. 5251 is available from any stockholder in the UK but in mainland Europe 5052 would be the nearest. 3103,3003 and 5005 are a bit softer and 5754 H111 a bit harder. All would be adequate.

The term " aircraft grade " makes me laugh. It's meaningless drivel that is just designed to imply quality and command unjustified prices.

I wish that I could TIG weld. Only done MIG on thick sheet.

Mike, do check that your TIG welder has an AC setting, this is fairly crucial for alluminium, although if you've welded the soft stuff before I'm sure you know this already. TIG is the most gentlemanly method of welding, compared to the anti-social behaviour of a MIG it's pleasurable.
