Dear Experts,

My query is that, is there any mandatory by TPI approval (Seal and Sign) on every WPS ?? even though they have already sign into the supporting PQR'S....

KINDLY CLARIFY WITH RELEVANT CODES AND STANDARDS.


Thanks & Regards

Venkat

Dear,

As per ASME Sec IX 2019, there is no requirement of third party.all the clauses regarding review by authorized inspector has been repealed. So if you are qualifying according to 2019 edition,  third party sign and seal is not required.

Regards, 

Charles V Jacob

PQR and WPS are different.
WPS is procedure for performing the welding on jos. PQR is like performance test to check if this welding is possible.

Not necessarily. But as per 2019, competent welding personal should be available to review welding related documents within company.

No. TPI can witness PQR and can review WPS. TPI can't Certify PQR and can't Approve WPS. In ISO as examining body, they can certify WPQR not WPS.

Each organisation can certify WPS/PQR. refer ASME Sec-IX- QW 201,  TPI review/witness is NOT mandatory,

TPI review / witness is Not code requirements, this is to satisfy customers that they have qualified WPS/PQR  upfront with third party check than vendors own personal. 

Also note, code allows SWPS - Prequalified WPS, means u can understand that does not require TPI involvement ! 


Thanks and Regards

TPI not a ASME Code requirement.

But it depends on Client Specification and Client Acceptance. Generally it is a practice to Qualify Welders &  PQR's with reputed TPI so that it can be Accepted by all Clients.

Just to add,

If it a Heavy fabrication shop fabricating heavy equipments with ASME stamp you can use your AI.

If it is a plant construction site, normally client requires PQR qualified at site

If it is code stamped equipment, TPI witness or approved WPS can not be used. It is the responsibility of manufacture

For projects in middle east it is almost mandatory that a TPI is used although it is not a code requirement. In other countries u may follow what is prevailing in those countries.

If you are working to ASME no third party witness is required.  Your Authorized Inspector (AI) will definitely have involvement but they are not required to witness WPS involvement.

 

If you are working to AWS no third party witness is required.

 

If you are working to ISO 15614, third party witness by a Notified Body (NOBO) is required.

 

If you are doing structural work for Canada.   CWB witness is required and a retained Canadian Chartered Engineer is typically also required for companies operating outside of Canada.

 

If you are interested – my experience – hope it helps.

When PED (2014/68/EU) is applicable yes (see Annex I - 3.1.2), the NoBo has to approve the WPS,.
When ASME is applicable No. In ASME the manufacturer certifies the PQR, the WPS not
