Re: [MW:5052] Pipe or Plate PQR ?

Hi,

 

Please note that PQR is mainly intented for proving the mechanial poperty of weld. Position is not the matter in case of ASME Sec IX if impact test requirement is not applicable.

 

In case of impact test  requiement, if you qaulify the PQR in 3G position (highest heat input position) it will qualify all position.

 

If your production weld is in 5G position you have to qualify the welder in 5G or 6G position to prove the skill of welder.

 

If the qualifiation is for pipe line as per API 1104, dia, thikness and position is matter.

 

Regards,

Muhammed Ibahim PK

Dear I have one observation. The position of welding is also important. If it is a 5 g position actual welding , will you be able to use plate for process qualification.

To: materials-welding@googlegroups.com Date: Tuesday, 4 May, 2010, 9:58 AM Hi, PQR you can use either plate or pipe..it doesn't matter...pls.rfer to QW-451 for PQR qualification limits...PQR is for P number,Welding Process,thickness .filler metal ,process...etc...its better to do the PQR with Plate for easy for welders and Procedure qualifications...Pipe diameter limits mentioned in the Section-IX only for welder's qualifications.You can use the PQR with Plate for Pipe also..When you qualify the welders for pipe  you can use the same PQR of plate with the Thickness limits and all other essential variables mentioned in QW-250 to QW-265 according to the process you are using for PQR. If u have any doubts feel free to ask..   Thanks & Regards,   (Karthik) Karthikeyan.S   Getabec Energy Co.,Ltd. 379,Moo6,Soi8,Nikhomphatana, Rayong-21180, Thailand.

To: "Materials & Welding" <materials-welding@googlegroups.com> Date: Tuesday, May 4, 2010, 10:33 AM Hi dear all Please somebody tell me if I can use a plate PQR for qualification a pipe WPS according to ASME Sec. IX? I could not find any thing about that in ASME code. If it's possible then why there is pipe diameter limit in PQRs? Please refer to ASME paragraph.
