No. As per QW 452.3,

1'' OD qualify from 1" to unlimited size.

To qualify for 3/4", he has to get qualified in the actual size and the qualification range

is from 3/4" to unlimited.

Hi!

As per ASME code

If welder is qualified on

1" OD pipe ---He is permited to weld 1" and above OD pipe

If qualified on less than 1" OD pipe then he is allowed to weld on Dia of pipe welded to unlimited

The Dia at weld joint is to be considered

Dear Mohd.,

Even if the welder qualifies with 2" NPS pipe, the qualification is from 1" (25mm) OD. This itself will suffice for welding 3/4" NPS pipe as the OD is 26.7mm. Surely, if the welder is qualified with 1" NPS pipe, he can weld 3/4" NPS Sockolet. But, please note the thickness range the welder is qualified for and evaluate against the sockolet thickness and then depute for welding.

Thanks and Best regards,

K.Rajagopal

According to my understanding, if a welder is qualified with 1" NPS pipe (the OD is more than 1 inch and in actual 1.315 inch) he is qualified from 1" OD and above.

When we consider the 3/4" NPS pipe, the OD will come 1.050" which is over 1" so he is qualified to weld (even for the pipe to pipe butt weld).

Now the case of O'let weld, I cannot understand in which angle we can consider a O' let weld is a fillet weld?? its a groove weld with a fillet weld cover. Normal Joint configuration is as per ASME B31.3 Fig328.5.4D (1)

So both WPS and welder shall be qualified for the Diameter and the thickness "Tb".

Please don't confuse, your welder is qualified to weld 1'' and above outside diameter on groove joint.

Other way you can tell 3/4'' NPS and above for groove weld. Outer diameter of 3/4'' is 26.7 mm (more than 1'').

Please check the table QW-452.3 (ASME Sec.IX) for groove weld and for fillet weld you can use him any diameter and thickness

as per QW-452.6 because he have the qualification on groove weld.
