Does anyone have a old 3000 front shroud they are cutting patches from? The BJ8 shroud I have has a piece on the lower right size the was torn off at the frame mount area,

There is a front clip= Shroud for sale on the Joppa auction site
 
Wow, lots of good stuff there! My shroud is good, just need piece/strip of aluminum at the bottom to weld in. Thought someone here would have damaged shroud I could get a piece from.

OH!! OK a piece of 00 aluminum should let you fabricate a replacement and then weld it in.
 
How are you going to attach the replacement piece? Glue or aluminum .weld?

Marv, Healeyblue,

Many of us are not equipped or skilled at work with aluminum and, as I understand, TIG welding aluminum pieces having different compositions and coefficients of expansion stress the skills even further. Structural bonds (glues) are being made and used by major auto manufacturers during construction and to attach aluminum replacement structures damaged in an accident.

What approach have you used, or are planning to use, to apply the patch to your shrouds as a friend is doing a major restoration on a BJ7 which requires applying a patch panel to his rear shroud.

Oxy/acetylene is always an option too.

I have a friend who is an excellent aluminum welder. O/A torch can be done but you do have to know what you are doing.

You one lucky fella!--:applause:
 
MIG with a spool gun is easier than TIG, at least for me. Of course, one needs to use aluminum wire in the spool gun and pure argon gas instead of the CO2/Argon mix used for steel.

I did not know you could use a MIG with aluminum wire and Argon to weld our Aluminum. Since our shrouds are aluminum alloy, what is the composition of aluminum wire you are using? Sorry for my total lack of understanding in this area as I have always been told that welding aluminum took special skill and equipment and not something for the casual doer to attempt. As a result, the introduction of high bonding glues designed for such as Audi, Mercedes, and GM truck seemed a good alternative.

Thanks Guys for your responses,

They were not pulling your leg.:encouragement:
 
The aluminum alloy of the shroud is 3003. It is readily available from any metal supplier in sheet form. I believe it is .060" thickness. If you can gas weld with any dexterity you can TIG weld. The biggest drawback to TIG welding is the cost of the equipment. But, then there are the aluminum spools that you can add to a MIG welder. I have never used one. I suspect they lay on a bead of aluminum that you then have to grind off to make things level. With a TIG you can fusion butt weld with minimal use of filler rod.
 
MIG on aluminium works fine with a generic filler wire and argon shield gas. Sure TIG is "better" and one can buy specific alloy types of rod but frankly it's only a car body not engineering critical in any way. I am reinforcing my clip mounts as one is partly cracked I simply formed some alloy sheet and will blind rivet into place before re bolting. I could use glue too if I did a smear of polyurethane would do the job over the available surface area.
