welding round tube - TIG or MIG
Let's say I want to make something like this:
Unlike locost chassis, the joins will be exposed so ideally should look as nice as possbile, ideally without having to dress the welds afterwards.
Would a reasonably skilled MIG operator (i.e. me) be able to achieve a nice finish or would a TIG make it much easier to do that?
By nice I mean an even bead of weld without bubbles, lumps ofbits of wire poking out! 
The tube is mostly 32 mm x 3 mm wall ERW.

Either.............if you can weld!
TIG is generally neater, but requires very accurate cutting of the pipes where they join. If they are close enough, they can sometimes be tigged
without a filler rod.
Mig will look ok if you get your current settings low enough to penetrate, but not lay down a thick weld.
It just takes practice with either method.

My understanding is that TIG is quite slow so for a big chassis MIG has an advantage... Then again, TIG welds often look neater than MIG so I guess
it's a time vs appearance type thing.

Do you have the welding kit to do either or would you have to "sub-out" the TIG work?

IMHO...a nice looking MIG weld is not necceserily a strong one....

I have the MIG this post is leading as to what TIG I'd need to the the above.
In an ideal world it would be nice to have AC TIG to do aluminiumninium but I would settle for DC to do the above.

but a nasty looking one is NEVER a strong one....
so statistically, a nice looking one is stronger....

Generally good welds never break........the material around them gives way first.

as said at the top, "either, if you can weld"
it makes no odds, either will do, though TIG will take much longer
Retro RWD is the way forward...........automotive fabrication, car restoration, sheetmetal work, engine conversion
retro car restoration and tuning
