"Additional Requirements"...... The essential variables of QW-361.1 and QW-361.2 plus any additional additional requirements (i-e additional variables) of QW-362, QW-363 and QW-380 may require requalification of welding operator.

Thanks for elaboration , what i understand that QW-361.1 & QW-361.2 are essential variables and QW-362, QW-363 and QW-380 variables may not be imposed for qualification of Welding Operator.
Now question is
Is its mandatory to refer the QW-453 for Welding Operator qualification ?
( Kindly note that QW -380 is referring QW-453 for qualification )
