Guide to Update A Procedure Qualification Record (ASME IX)

QW-200.2 states: Each organization shall be required to prepare a procedure qualification record.

Procedure specification record (PQR) is a record of variables recorded during the welding of the test coupon.

In this article is a guide to prepare PQR for

  • Process: GTAW, manual
  • Material: ASTM A312 TP316/316L

TEST RESULTS

Tensile test (QW-150)

The test values were taken from lab test report, the minimum information shall be recorded test method, test specimens and its dimensions, test result, location of break.
qw-150

Guided Bend Test (QW-160)

There are 4 specimens subject to test
qw-160

Hardness test

We strongly recommend to conduct the hardness test on PQR, If WPS require to comply with NACE, hardness test shall be accordance with NACE MR 0175 part 2 or 3.

Limitation of hardness value are depend on base metal application.

Note: test method and test values.
hardness-test

Toughness test (QW-170)

Minimum 9 test specimens at base metal, weld metal and HAZ.

[IMPORTMANT] In case of thicker metal and two or more welding process, each of process shall be included in the test.
qw-170

Other tests

Additional test should be report in PQR (if application)

Welder and Test laboratory

Welder who passed qualification of test coupon, also qualified his performance. We need to issue a certificate to meet QW-304.
welder

Some clients/projects may require laboratory test body that they have to qualified ISO 17025. The lab test boby certificates should record in PQR.
