Dear Sir,

Situation:
Welding of pipe branch connection with RF pad.
Header size: 20mm; Thickness of RF Pad: 20mm
Branch pipe thickness: 10.97mm
Whether PWHT is required for the branch connection?

As per ASME B 31.3, Clause 331.1.3 (a), the PWHT control thickness is the lesser of the below two conditions,

(1) the thickness of the weld [ As per clause 331.1.3 (b) (5) the control thickness of branch can be calculated.]

(2) the thickness of the materials being joined at the weld or the thickness of the pressure-containing material if the weld is attaching a nonpressure containing material to a pressure-containing material.

Here can i consider (2) as 20mm as that is the thickness of the material being used in this situation and consider the same as the control thickness for PWHT?

1. Please refer AWS D1.1 , Part C for performance qualification requirements.

Range of qualifications - pl refer Table 4.10 & 4.11

2. Combination of WPS is allowed as per 3.6.1 This is applicable for both qualified or prequalified WPS.[ Screen shot from 2015 edition as below ]

Also refer OLD AWS interpretation as below [ 1984 edition]

Re: [MW:28522] PQR

QW-201 Manufacturer's or Contractor's

Responsibility

Each manufacturer or contractor shall list the parameters

applicable to welding that he performs in construction

of weldments built in accordance with this Code.

These parameters shall be listed in a document known

as a Welding Procedure Specification (WPS).

Each manufacturer or contractor shall qualify the WPS

by the welding of test coupons and the testing of specimens

(as required in this Code), and the recording of the welding

data and test results in a document known as a Procedure

Qualification Record (PQR). The welders or welding operators

used to produce weldments to be tested for qualification

of procedures shall be under the full supervision and

control of the manufacturer or contractor during the production

of these test weldments. The weldments to be

tested for qualification of procedures shall be welded either

by direct employees or by individuals engaged by contract

for their services as welders or welding operators under the

full supervision and control of the manufacturer or contractor.

It is not permissible for the manufacturer or contractor

to have the supervision and control of welding of the test

weldments performed by another organization. It is permissible,

however, to subcontract any or all of the work of

preparation of test metal for welding and subsequent work

on preparation of test specimens from the completed weldment,

performance of nondestructive examination, and

mechanical tests, provided the manufacturer or contractor

accepts the responsibility for any such work.

The Code recognizes a manufacturer or contractor

as the organization which has responsible operational

control of the production of the weldments to be made

in accordance with this Code.

If in an organization

effective operational control of welding procedure qualification

for two or more companies of different names

exists, the companies involved shall describe in their

Quality Control system/Quality Assurance Program, the

operational control of procedure qualifications. In this

case separate welding procedure qualifications are not

required, provided all other requirements of Section IX

are met.

A WPS may require the support of more than one

PQR, while alternatively, one PQR may support a

number of WPSs.

The manufacturer or contractor shall certify that he

has qualified each Welding Procedure Specification,

performed the procedure qualification test, and documented

it with the necessary Procedure Qualification

Record (PQR).

Hello experts, is there any code/standard reference for below statement?

"If a PQR is qualified for one location of company, same can be used for another location provided the other facility/location is under same technical And Quality administration as of the qualified one"

Regards,
Vivek.
