ASME Section IX is a..... code that can be superseded by..... code: ANSWER
Support. Construction.
A method is... (welding-related). - ANSWER A written document instructs the
person joining the material.
What is the purpose of qualifying a procedure (PQR)? - ANSWER To ensure that it
can generate the correct mechanical qualities of the joint, the joining process must
be performed by a skilled individual.
What should the PQR document contain as a minimum? - ANSWER The important
factors and outcomes of the needed tests
Tension tests (QW-150) are used to test the... - UTS of groove-weld joints.
, The guided-bend tests (QW-160) are used to evaluate... - ANSWER The strength
and ductility of groove-weld joints
RT/UT may be considered an alternative for.....(QW-141) to demonstrate a welder's
ability to make sound welds. While they can be used to qualify a welder, they
CANNOT be used to qualify a.... Mechanical testing. Welding Procedure.

If the specimen breaks beyond the weld or weld interface, it may be acceptable if
the strength is no more than.....% below the base metal's minimum UTS -
ANSWER 5.
QW-163 bend tests: The guided bend test should have no..... in the weld or HAZ
exceeding.... in, measured in any direction on the specimen's surface after bending.
..... appearing on the corners of the specimen during testing shall not be accepted
unless there is clear proof that they are caused by a lack of....,...., or other..... -
ANSWER There are open discontinuities. 1/8. Convex. There are open
