[MW:17563] CC & CV ?

Dear Experts,
 
I wonder if someone can tell me about the role of the frequency and the differences between constant current and constant voltage on penetration, welding profile (bead) and other properties in Submerged Arc Welding?
For 2 wires (Tandem) in outside and inside, lead and trail, which one will give the best weld profile? CC or CV?
 
Regards,
Ramin
