[MW:13776] SS welding with SAW

Dear Experts,
Could anyone suggest me about the followings for stainless steel SAW welding to reach >0.38mm %LE at -196deg. cen.

 

1. Limitation of wire composition for ER308L grade wire.
2. SAW welding parameters. (A/V/Speed)
3. Preheating & Heat input for more than 50mm thick plate.
4. Any other special requirement.
