well, at least in my thinking   |
The metal STILL remains in a semi plastic state for hammer welding. Its not room temp cold.. Whether its heated with an OA torch..an electric furnace..MIG welder or ,,whatever...its still "red hot" right prior to hammering into "final shape".
If ya think MIG welded items get cold quickly....
...Ive got a nice set of leather gloves with scorch marks to show you!
