Dear All,

Does butt weld WPS is applicable for socket weld? Can anyone provide ASME IX code reference for this ?

No it is not. For every configuration you should draft a specific WPS. However a WPSS for socket welds could be supported by a PQR done on button welds if all essential variables are within PQR approval range

If the join design is not essential variable for that particular process and all the other essential variables are within the PQR range, the WPS for butt weld will be applicable for fillet and socket weld join designs which specified in the applicable code for fabrication and erection (ie, B31.1, B31.3 etc.)

Sorry to disagree –a socket weld is simply a fillet weld and a WPS can be written from a groove weld PQR to cover all fillet welds in addition to groove welds.  See Table QW-452.6.  Fillet welds must be referenced on the WPS and additional information for setting up the socket weld will have to appear on fabrication drawings or be included on the WPS (i.e. the 1/16 inch gap prior to performing the weld).  A separate WPS for each weld configuration is not required by ASME – typically referenced to fabrication drawings.

The issue is that when you are checking the isometrics issued for fabrication you never find this details and  especially the 2 mm gap

We should not confuse between the WPS used for the PQR and a WPSS which will give direct instructions to welders on how to perform a specific weld.

If they are an experienced fabricator, the 2mm gap is understood, of course that is assuming proper pipe fitting/fabricating training.  Many shop detailers of isometrics may not even know about the gap, so it doesn’t get put in the isometric drawing notes.

You can get goint preperation "fitup" from conatuction code you can find it at B31.3 for process piping and B31.1 for power piping.
