I want to qualify welders for FCAW. There are two options for welder qualifications, either bend test or radiography. Does the Radiography test is mandatory or Ultrasonic test can be done in place of Radiography ?
Radiography is not mandatory for AWS D1.1. Radiography or Guided bend testing can be performed. Ultrasonic testing is not addressed for performance qualification at all in D1.1. only for procedure qualification.
Clause 4 will have all of the details for those requirements.
