Subject: [MW:7314] WPS FOR DOWNHILL WELDING

Dear gents, Could anybody help me for the following concerns, We have a company approved PQR and WPS for welding P1 to P1material with GTAW process .Now we need to use this WPS for down hill welding. Materials, consumables process are same. According to ASME 1X welding progression is non essential variable for WPS and essential variable for welder qualification.So only welder qualification is enough for using the existing WPS for down hill welding? Thanks and regards
Suresh
