Re: [MW:22383] WPS for small bore

Dear Manoj,

Check your client and construction code requirement for any restriction/limitation  of welding process to use. If the existing WPS & Welders are qualified as per ASME Sec IX , then using the supporting PQR which you have for GTAW+SMAW, you can prepare a separate WPS with only GTAW process- if the PQR variables are within your required range.

Dear WinarKo,

The answers are pertaining to ASME sec.IX. In AWS D 1.1, the procedure limits for Diameters too.

Kindly clarify, whether it is for pipe welding as per ASME or any structural application.

Thanks and Best Regards,

K.Rajagopal

Diameter is not an essential parameter for WPS qualification. So no need for a new PQR (unless other essential variables are affected)
Diameter is an essential variable Only for welders qualification.
A WPS has always to reflect the actual welding configuration, So even no need for a new PQR the WPS needs to be edited again
