Welder qualification for the specific branch weld requires welding a full-scale test coupon that replicates 

the branch weld dimensions, followed by destructive tests—primarily nick break, root bend, and face bend 

tests—prepared according to the specimen configurations in Figures 10 and 11, meeting requirements set 

forth in Clauses 5.7 and 6, and Tables 6 and 7 of API 1104, 21st edition.
