hi Abdul, QW 401.1 and QW 401.2 are different. QW 401.1 is specifying about procedure. QW 401.2 is specifying welder ability. When you are preparing welder or review welder certificate or administering of welder, the thing you need is QW-401.2 (not QW-401.1) Rgds 2011/8/1 Suresh <bobsuresh24@gmail.com> Dear Abdul .. First you need to mentioned clearly that for what requalification needs? ,Welder perfomance or Procedure Qualification ? Suresh

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.
