welding "Hiduminium"

By KWynn Date 02-17-2001 21:57

I have a part fabricated from .125 "Hiduminium" sheet. I don't know much of anything about the alloy, except that it's supposed to be around 95 Al, 4 Cu, and 1 Mg.

someone has stamped some markings into the surface. to restore the original appearance, I need someone to weld over them. very little penetration would be necessary. from there, I can take over and smooth things out.

any ideas who can successfully weld this? or any additional info on "Hiduminium" would be welcome. thanks for any help!

It stands for high ductility aluminium, and for the life of me I can't remember why I know this although I'm fairly sure it is a trade name. In the early 70's when they were using aluminium in house wire they added a similar amount of copper to improve workability.
As for blending the the stamp marks, you could try just flame blending using AC tig and argon for gas. Whenever I have to mess with disimilar metal I turn the wave balance to zero for maximum oxide removal
I hope this helps...Sean
