Re: [MW:3921] WPS & PQR clarification

Hi Mahendra,

First of all ....before any Qulification WPS and PQR ......you have develop a Preliminary ...or proposed WPS ....which will be base on material ...welding process consumable....and the scope of your application ...

According with Proposed WPS ...you will perform ...qualification .welding test.... base on you will record all data per runs ...speed ...heat input. .interpass temp....

After the welding test piece was done...after RT .is gone for mechanical test ....and base on will be issued PQR......according with your satisfactory results ...will be issued final WPS that  will be applied to future production welding (on wps will be specified the PQR numer supported)

regards

Dear Group

 

 Good day,

--------------------------------------------------------------------------------------------------------------------------------

Still I have confusion on WPS and PQR terms.

 

1. WPS to be created  first , with respect to  selection of process, electrode and current  etc.

2. PQR is developed  after WPS ,by entering the the actual variation  relevant to the WPS.

 

|Corresponding reference numbers are to be entered  in each other.

 

This is the information  from ASME IX codes.

 --------------------------------------------------------------------------------------------------------------------------

But there is a controvercial  statement  from some of our colleques, PQR to be developed first and  Supporiting PQR  reference number is to be entered in the WPS.

 

Please clarify this confusion .
