[TheForge] I don't get it...

[Bruce Freeman]

At forge-welding temperature, oil isn't oil anymore.  It's just another
source of carbon and hydrogen.

Electric welds don't heat the metal generally or for as long, so grease
may perhaps remain grease in a TIG weld.  Just speculation.

Pete:  I doubt that a forge weld is enhanced by the presence of any
foreign
material, except in that material's capacity to act as an oxygen
barrier (a
la flux).  I have no solid proof, one way or the other, however.

supposed to consume the oxy)...
