Welding titanium?

[race-rodz-inc]

i weld Ti from time to time (motorcycle exhaust), as far as i know... it can be mig welded, you must also do all welding in an inert atmosphere(argon bubble).... material has to be absolutley clean, and cool down after welding is key. they say it can be welded in a clean area with no air drafts...but i have never had any luck with it. as for doin a complete frame..... yes it could be done, but the cost involved both in materials and set-up would make me think its not much of an option.

if your looking for lightwieght material... look to chrome moly, but once again it also needs to be tig welded. if you looking to be able to "tie" the frame back to the body... then mild steel is gonna be your best choice. i would think the cost involved doing anything other than mild steel would outwiegh the 75-100lbs weight savings. that figure is based on a full tube chassis drag car, chrome moly vs mild steel.

good luck...let us know what direction you go
