Sir.
1. What Group of SS and DSS?
2. Welding process?
3. What method did you use for the Corrosion test?
4. Temperature: your client requirement for a test?
5. Heat input while welding, Interpass temperature?
6. What type of Argon is used for Purging Gas and shielding?
7. Branch of welding consumable.
