Recommended preheat for welding 6061T-6 Aluminum 1/2" through 2" thickness with GMAW using 3/64" and 1/16" diameter ER5556 or ER5356 electrode?

The laws of phisics being universal, You get the same answer no matter where You post it.

In heat treated aluminum, You have to keep heat input as low as You can to preserve as much of the increase in strength increase caused by heat treatment as possible. Even at best, You will loose a great ammount of strength.

Preheat is best avoided alltogether.
