Dear Ilangkumaran,

Mr.Pandithan is Right
Electrode Diameter is a Supplementary essential variables means Applies only when there is a Impact Requirement. 
Otherwise deviation of Electrode diameter from the qualified WPS is not a problem as per ASME IX

It is always use small electrode to avoid more heat input and for slang inclusion

Dear Experts,
 
               While my routine inspection of welding I have noticed Diameter of the electrode used for the capping was not as per the qualified WPS and I was told the diameter of the electrode is not an essential variables.
 
  WPS for SMAW
 
Now as per the sec IX; Table QW-253
 
1) the essential variable QW-404.30
 
2) Supplementary variables QW-404.7/.12
 
3)  Non essential varaiable QW-404.6
 
       &
as per the QW-353
 
1) QW-404.15/.30 were the essential variables for welder qualification.
 
So if the diameter of electrode used in production welds beyond 6mm then only the WPS
needs to be re written? or Should we insist the welder to use what ever mentioned in the qualified WPS? or the welder should use the electrode that he used while performing his WQT.
Can somebody expain me in details how to deal this?
 
Regards
Ilangkumaran
