8.5.3.1 Operator Welding
Once the parameters for a proper weld have been established and
used successfully, the trainees should start to make welds under
Instructor supervision. Change individual parameters to an
unacceptable value and coach trainees on readjusting them until
reaching an acceptable range.
Trainees having made successful welds should graduate to using
the actual customer pipe, with the Instructor assisting in weld
development.
