Dear Harikrisnan,
It is not mandatory to do the welding in Uphill progression as per ASME Sec. IX.
See Clause No. QW-405.3 for better explanation.
If you change a progression in vertical welds then please check, is the welding consumable is recommended to weld in the same progression?
Check with respect to ASME Sec.II Part C.

Dear Friends
What is the criteria for selecting Uphill/Downhill weld progression in a Pipeline/Piping? Is it mandatory to use uphill progression in a WPS qualified under ASME Sec IX ?
Thanks and Regards
