Ok, sorry for posting in this old thread but I was among the first batch of graduates to complete the Welding Specialization within my engineering program at UW.Originally posted by The Tesseract
I want to make a low-rider or chopper bike frame.
I have to get materials first, but I imagine that will be harder than the actual welding equipment.
Which is easier? WIG or TIG?
and more importantly... which is stronger?
I know, i realized my mistake afterOriginally posted by adorablehomeboy
WIG is TIG Welding.
The bike would be a completely road (more or less) frame, and so would be made from double butted aluminum. I'm sure i can get that stuff no problem, thanks to a source of mine.Originally posted by adorablehomeboy
Welding will be a skilled trade soon in Canada, because it is NOT easy. AND, you are going to be fitting some pretty weird angles I assume making the frame. If you can actually get this thing to hold, after some dynamic loading caused by you riding it it's going to break, while you are riding it....
Find out what other bike frames are made of...
Nope... just regular 6000 or 7000 series aluminium... 6061 or 7005Originally posted by adorablehomeboy
You want it to look nice and be tough (as in the best combination of strength and ductility)? You'll want a brushed titanium or chrome moly steel.
Titanium is not that expensive... but it's not exactly easy to obtain either. It's only when parts get smaller does the material go up in price. Bulk order of Ti is actually cheap... at about $10-15/lbsOriginally posted by adorablehomeboy
Titanium will be expensive as hell, and chrome moly will be too.
more shit i know...Originally posted by adorablehomeboy
Welding both are different. Titanium has to be cleaned and welded right away, and completed gas shielded when welded. Chrome moly or other types of steel you have to be careful about the cooling rate, you could end up with a brittle joint, liquation cracking, stress cracking etc....
I did welding in Grade 10 (or was it 11?)Originally posted by adorablehomeboy
So I don't know how much welding and fitting experience you have, but if you are welding something structural please be careful!!
My experience after having taken a cpl courses at community college is that TIG welding is hard to do well. Give the job to somebody who knows what they're doing or you'll be disappointed with the results.Originally posted by The Tesseract

granted, that was about 10 years ago... I still remember how to do it. It was easier than sodering... i remember that for sure.
