Hi,

Is someone able to explain the Sec IX QW 200.4 (B)to me...

Thanks
 
The short of it is that it permits you to use multiple PQR's to support a WPS, if the PQR was qualified on 1/2" material or greater. This is most useful in creating dual-process procedures (such as GTAW root pass with SMAW fill), and for increasing thickness qualified.
