Dual mass flywheel welding
Discussion
Wouldnt have thougth so, not in a cost effective manner that could be guaranteed, by the time you take in labour costs the flywheel is only part of the cost and having to get it welded and potentially have to take ti out if the welds give then buy another flywheel and put that back is too much if a risk I would say.

Not really.It's over-complication of components you would expect to be long-lasting which actually expire long before the rest of the car and require replacement - sometimes at a greater cost than the car itself.
Mazda 6s are cheap cheap, but I still wouldn't like to see what might happen if you tried bodging a DMF together!
I'm guessing it's a 6 cyl engine. They have perfect primary and secondary balance, so the flywheel isn't helping there. I'm guessing it's for torsional vibration purposes, so changing to a straight type flywheel, you probably won't notice any difference. But, there always is one, if it's there to damp or shift the torsion vibration frequency of the crankshaft, then it's possible the crankshaft may suffer a fatigue failure, if it now runs at one of it's harmonic frequencies fairly often. Motorway cruising?
The reason you don't weld them:
a DMF kit permits a degree of torsional deflection by having a sprung flywheel. The clutch plate itself has very limited torsional deflection as it is designed to work with the flywheel.
an SMF kit has a solid flywheel but a much more sprung friction plate which permits the deflection.
A solid flywheel and a clutch plate with little/no 'spring' will result in a very nasty driving experience indeed.

Nope. Mazda6 had four cylinder engines only.
