Re: [MW:12050] change in welding Technique does it require Requalification ?

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)

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.
