Dear Muthu Bharthi,
It is required to qualified new PQR as per IS 7307 (APPROVAL TESTS FOR WELDING PROCEDURES - PART 1: FUSION WELDING FOR STEEL)
Para 4.1 A welding procedure test shall be required when any of the following changes are made to an approved welding procedure:
(f) - Any changes in type of electrode, filler material, flux or shielding gas.
While IS 7310 - 1 - Title it self says that APPROVAL TESTS FOR WELDERS WORKING TO APPROVED WELDING PROCEDURES - PART 1: FUSION WELDING OF STEEL , hence it is not applicable for WPS/PQR qualification.
