Grade of aluminum in VisionTech aero bars

This may be in the wrong section but I thought frame builders would have the best suggestions on welding aluminum. I got these old vision tech aero bars for $12 on ebay. They are for a 1" threaded fork but were cut off the the bike to save the fork. They also have some paint bubbling and flaking off. The bars were originally crimped on the pipe that goes in the fork but that has been removed. I have access to a tig welder so I thought welding a new pipe in would pe plenty strong. I have a couple questions though:

1. Does anybody know what type of aluminum VisionTech uses in their bars? My understanding of welding in general is that the material of two welded pieces need to match as well as the filler rod.

2. Is it possible to find the pipe that was crimped on the bars? I have been looking and am only able to find the things that convert from 1" threaded to 1 1/8 threadless.

3. Is it safe to strip the paint off these with aluminum safe paint stripper? I couldn't find any information on how the joints are put together and thought if they are bonded, stripper might be a problem.

I figure if I can fix them, they'll be ugly but a lot cheaper than new and a fun project. If I can't, then I'm only out $12. Thanks for any help. Also, if there is a better place to post this, please let me know.

A good rule to live by: Never buy used aluminum bike parts...especially handlebars.
I dont think any responsible builder would recommend welding on old bars for actual use.
I'd say if you have a tig welder and can weld aluminum, using those bars as a template and building your own out of 4130 would be no big deal for you...and a hell of a lot safer.

too many unanswered questions to safely weld those back together. Hang them in your clubhouse and make up a good story about them
