Hi ! To get good Impact properties in SS weld you should i) Flux should be of basic nature having bsisity bet 3-3.5 ii)Interpass should be max 150C iii) No preheating for SS iv) Adjust current Voltage and SAw speed to get bead height not more than 2.5mm Try to cool the weld as fast as possible Regards Hegde P.B.

Dear Experts,
Could anyone suggest me about the followings for stainless steel SAW welding to reach >0.38mm %LE at -196deg. cen. - Limitation of wire composition for ER308L grade wire.
- SAW welding parameters. (A/V/Speed)
- Preheating & Heat input for more than 50mm thick plate.
- Any other special requirement.
