AWS Welding Codes & Standards Flashcards

Which AWS standard governs structural welding of steel and is most widely referenced in building construction?

Answer: AWS D1.1

AWS D1.1 Structural Welding Code—Steel is the primary standard for welding structural steel in buildings and bridges.

Under AWS D1.1, what is the minimum preheat temperature required for A36 steel with a thickness greater than 1-1/2 inches when using SMAW?

Answer: 150°F (65°C)

AWS D1.1 Table 4.5 requires a minimum preheat of 150°F for A36 steel thicker than 1-1/2 inches.

AWS B2.1 is primarily concerned with which aspect of the welding industry?

Answer: Specification for Welding Procedure and Performance Qualification

AWS B2.1 covers the specification for welding procedure and performance qualification across multiple processes.

Which document published by AWS defines requirements for the qualification of welding inspectors?

Answer: AWS QC1

AWS QC1 establishes the standard for AWS Certified Welding Inspector (CWI) qualification requirements.

In AWS D1.1, a Prequalified Welding Procedure Specification (PWPS) must conform to all prequalified requirements so that which step can be omitted?

Answer: Procedure Qualification Testing (PQR testing)

A prequalified WPS exempts the fabricator from conducting destructive Procedure Qualification Record (PQR) testing.

Which AWS standard specifically addresses welding of pipelines and related facilities?

Answer: AWS D10.12

AWS D10.12 provides guidelines and recommendations for root pass and fill passes in pipe welding.

The acronym 'EH' in AWS filler metal classification (e.g., EH14) indicates what electrode characteristic?

Answer: High deposition, high-iron-powder electrode for SAW

In SAW electrode classifications, 'EH' designates a high-manganese, high-deposition wire designed for submerged arc welding.
