Dear Experts,     If the welding technique is changed does it require Requalification ? as the QW-401.2  it states.   QW-401.2 Essential Variable (Performance). A change in a welding condition which will affect the ability of a welder to deposit sound weld metal (suchas a change in welding process, deletion of backing, electrode, F-Number, technique, etc.).   were as the  QW-401.1 Essential Variable (Procedure). it states Welding technique as Non-Essential variable .   Which QW we have to follow  and why ?   comments plzzzzzzzzzzzzzzzz.   Regards ABDUL JABBAR KHAN
