The maker or repair work company (certificate owner) has shown on the job drawing that a weld joint is to be prepared with a 60-degree bevel and also origin gap of 1/16 inch. Unless the bevels are milled on precision equipment, it is doubtful they will certainly attain a specific 60-degree bevel as shown.

The nozzle axis is 90 to the flat head, and the add-on weld includes a 3/8-inch fillet weld. The examiner can conveniently gauge the fillet weld to make certain compliance.

The examiner needs to instantly ask the certificate holder regarding this situation. Maybe as straightforward as the certificate holder having actually simply not executed that action in the process yet, or maybe as poor as his or her having tried to save money and time by not beveling the ends.
