Very soon I am will be into a project that will require I plug and refinish some holes in relatively thick sheet metal ( approx .10 thk) What does one use when welding (mig) to back up the hole? I was thinking of a large block of aluminum since the steel won't stick to it and it would have sufficient mass to prevent the metal from flowing out of the hole. This procedure would sure make it much easier to finish the surface off since I should only have to grind one side flat since theocratically the other side would already be flat since the backing plate would prevent any protrusions. Anybody already been there done that, got a better idea etc.?
