Hi Gary, I missed seeing this thread, so I haven't seen any of the responses
except this one, so I'm probably covering old ground.
I very successfully TIG welded some cracks in my rear shroud several years
ago. It was a large Miler square wave machine, but they do make smaller
machines as well. Came out really nice.
Miller claims you can MIG weld aluminum, but I haven't tried it. I have a
Miller Challenger MIG welder that I've used for welding steel on my Healey.
Really nice welder if tyou are looking to buy a MIG welder. I believe you can
get a spool of aluminim wire for it, but as I said I haven't tried it.
Whatever you do, practice on alot of scrap before you try welding the shroud.
I don't remember the alloy used on the shrouds I think the designation was
different than what we use today. I was going to use 6061T6 alloy for a
repair on my front shroud, but I haven't done it yet. Be careful with
aluminum alloys if you weld in a patch with new material; some are weldable,
some are not.

<Thanks to all for their response on mig welding the aluminum shroud. After
reading the responses, I didn't feel that it would practical. Then a lister,
Richard Pratt, offered to discuss it at length via telephone. Rich spent a
lot of time, trial and error mig welding his shroud. He shared his findings
with me and I am going to give it a shot.
It will be a little while but when finished, I will share my findings with
the list.
Thanks,
