Under AWS D1.1, an essential variable change in a WPS requires:
Answer: Requalification of the WPS
Essential variable changes affect weld quality and require the WPS to be requalified through new testing.
What is the purpose of a Procedure Qualification Record (PQR)?
Answer: Document test results that support a WPS
A PQR documents the actual welding conditions used and test results that qualify a WPS.
AWS standards are developed and published by which organization?
Answer: American Welding Society
The American Welding Society develops and publishes all AWS standards including D1.1, D1.2, and other codes.
Under AWS D1.1, complete joint penetration (CJP) groove welds in tension must be examined by:
Answer: Radiographic or ultrasonic testing
AWS D1.1 requires RT or UT for CJP welds in tension-loaded joints to verify full internal soundness.
What does 'prequalified' mean in the context of an AWS D1.1 WPS?
Answer: The procedure meets code requirements without qualification testing
A prequalified WPS conforms to all AWS D1.1 prequalified requirements and does not require procedure qualification testing.
The primary purpose of interpass temperature control in AWS codes is to:
Answer: Prevent excessive heat buildup that could degrade mechanical properties
Controlling interpass temperature prevents the weld from overheating, which could cause grain coarsening, reduced toughness, and property degradation.
