Mr.John
can you refer me the standard that mentioned this thickness limit for GTAW

Just in case if I specify in my WPS that I'll use GTAW process for root
pass only and SMAW process for fill passes. Keeping in view SMAW process
qualification range (up to 14.22 mm), will my WPS qualification range not
up to 14.22 mm?
