Qualification of PQR

[blaqesmith]

Please reply as per ASME Section IX
Can we use turned specimen ( Tensile) for qualification of PQR.
Material: 516 Gr 70
Thickness: 16 mm
Process : SMAW
Electrode: E7018
PWHT/PRE Heat: N/A
See QW 151.3 & QW-462.1 (d)

Please review ASME Section IX
QW-462 TEST SPECIMENS
The purpose of the QW-462 figures is to give the organization
guidance in dimensioning test specimens for tests
required for procedure and performance qualifications.

Now look at Figure QW-462.1(d)

I am asking about QW 462.1 (d). Can i use this type of specimen for tensile testing while i am using a plate of 16 mm thickness.

Yes,
You will need your sample to comply with the requirements of (b) 0.353 specimen

@DD
why 0.353
as per note "a" of figure QW-462.1 (d), we can extract sample having diameter of 0.505. so should i move to 0.505 or 0.353???

 

[metengr]

For a 16mm thickness you go with the specimen diameter that can be turned down to the diameter that meets 0.505" or 12.7mm.

Blaquesmith,
My turn to apologise.
My comment was based on dimension "C" Diameter of end section.
For 0.505" you require measurement "C" to be 3/4" (19mm)
You cannot get a 19 mm diameter out of a 16 mm plate.

However,

QW-462 TEST SPECIMENS
The purpose of the QW-462 figures is to give the organization
guidance in dimensioning test specimens for tests
required for procedure and performance qualifications.
Unless a minimum, maximum, or tolerance is given in
the figures (or as QW-150, QW-160, or QW-180 requires),
the dimensions are to be considered approximate. All
welding processes and filler material to be qualified must
be included in the test specimen.

Regards,
DD
