PQR tests per AWS D1.1

PQR tests per AWS D1.1

PQR tests per AWS D1.1

(OP)
Refer to ASME Section IX, Tests for PQR including
1. 2 pcs Tensile Test
2. 4 pcs Ben Test

I am not familiar with AWS. Tests are as same as Section IX, aren't they?

What about VT,RT or UT and Macro, they are mandatory required tests on PQR speciments per AWS, aren't thay?

RE: PQR tests per AWS D1.1

Yes they are the same per AWS D1.1

VT, and either UT or RT are required per AWS D1.1

Macros are typically used for fillet weld qualification or overlays.

RE: PQR tests per AWS D1.1

The essential variables listed in ASME and the required testing may not be the same as those needed to qualify a WPS in accordance with AWS D1.1 (assuming the conditions of prequalification are not met). The visual acceptance criteria used to evaluated a test sample per AWS D1.1 is different than ASME. AWS D1.1 requires each test sample be subjected to RT or UT before mechanical testing. ASME does not require any RT or UT of the test samples.
 
The thickness limitations of ASME IX apply only to the thickness of deposited weld as related to the joint(s) of a full or partial penetration weld and not to fillet welds.

AWS acceptance criteria is more stringent than ASME. AWS limits for the bend tests are no open discontinuities larger than 1/8 inch and no greater than 3/8 inch when summed. ASME has no sum limitation.

You may also want to check local and state building codes. Some engineers are not willing to push the envelope when building codes specify AWS for structural applications. Likewise, they do not accept AWS qualifications when they are working in a state that requires conformance with ASME for pressure vessels and piping systems, etc.
