WPS supported by more than one WPQR

[kjell123898]

Hi
Have any of you heard about if it is defined in any codes or standards whether it is possible to use two WPQR's to support a WPS for small bore tube welding in super duplex provided that all essential parameters in both WPQR's are equal but that each of WPQR's have different wall thicknesses and diameter. The intention is to expand the wall thickness and diameter range in the WPS.

Multiple PQRs are used to support a single WPS all the time. For Sec IX see QW-200.2 (f)
