Quieter alternative to angle grinding welds?

[voipio]

If the workpiece is acting like a sounder, there might be ways of damping down its vibration, by a suitable holding fixture, or a wet cloth. .

Yes, that won't help - I'm mainly grinding down the welds on my rear quarter panels, a 5' long section with effectively an echo chamber behind it.

no one mentioned filler yet

if you have a sand unit then putting a sheet steel flat onto it dulls the sound rather well

the same can be said if your grinding a frame

battery grinders run slower and as such make less noise ,, but for longer .
