Welding exhaust on-bike, safe?

[bogan]

if you get an current loop through the frame, you can generate quite a high voltage, bout 60V I've heard, so you wanna disconnect battery, ECU, anything else sensitive to high voltage, then you'll be good to go. Sounds like theres not a lot of difference regarding the type of welding either.

There is the small matter of current deciding to track through some bearing somewhere, and draw a wee arc.. that is, until it fuses itself together and is no longer a bearing.

You with a TIG? Now that's dangerous ... you bastard! hehe Make sure you get the family out of the house first! Lol

Oh, gee thanks, you!! Another vote of confidence I see!

AND for the record, I don't weld inside the house! Not a dumb idea though...

Yep as above disconect batteries and computers, as for bearings only if you are conecting the earth one side and welding the other.
If you can gas weld, tig welding is fairly easy to learn, though what you need to watch is the pickeling paste, that is used to remove the scale from the weld on S/S, dont get any on your skin, not only will it give you a chemical burn, but it also breaks down bone marrow, so wear good chemical proof rubber gloves when handeling the paste, I use a S/S wire brush and give the weld scale a quick brush down while the weld is still reasonably hot, this helps remove some of the scale before pickeling the weld, wash off the pickeling paste with plenty of water, use a scotch brite scourer to remove stuborn bits of scale, obviously while still wearing rubber gloves.
