Re: [MW:6604] Welding procedure Thickness range qualification

Hi, Please refer to QW-401.3 for definition of supplementary essential variables (A change in a welding condition which will affect the notch toughness properties of a weldment). QW-403.8 is an essential variable,it governs the minimum and maximum thickness qualified of the basemetal. QW-403.6 is an Supplementary essential variable.Please note that,If QW-403.6 applies, it modifies the minimum thickness qualified not the maximum. So if you want to change the welding condition which will affect the notch toughness properties of the weldment only,QW-403.6 applies.otherwise follow essential variable QW-403.8.

If we refer QW 451.1 is correct or not? If we see welding variables QW 403.8 is essential variable & QW 403.6 is supplementry variables. wat SEC IX says For welder thickness range qualification wat we have to refer? either 403.8 or403.6 ? Pl explain this?
