Read the first 6 AWS D1.1 Structural Welding Code flashcards as text

  1. AWS D1.1 applies to which type of structures?

    Answer: Structural steel welding (bridges, buildings, and other stationary structures)

    AWS D1.1 'Structural Welding Code — Steel' governs welding of structural steel in stationary structures such as buildings, bridges, and other civil infrastructure, excluding pressure vessels and pipelines.

  2. Under AWS D1.1, a 'prequalified joint detail' means:

    Answer: The joint has been tested by the AWS committee and requires no WPS qualification testing

    Prequalified joint details in AWS D1.1 Annex A have been thoroughly tested by AWS and are exempt from PQR testing — they can be used without a separate procedure qualification record.

  3. The Engineer of Record (EOR) on a D1.1 project has the authority to:

    Answer: Approve alternate materials, joint details, and accept weld quality deviations from the code

    Under AWS D1.1, the Engineer of Record has broad authority to approve alternate materials, modified joint details, acceptance criteria deviations, and other engineering decisions not explicitly covered or exceeding minimum code requirements.

  4. Visual inspection acceptance criteria for groove welds in D1.1 cyclically loaded structures require that undercut shall not exceed:

    Answer: 1/32 inch (0.8 mm) in depth

    For cyclically loaded structures per AWS D1.1, undercut in groove welds is limited to 1/32 inch (0.8 mm) maximum depth to prevent fatigue crack initiation at stress concentrations.

  5. What does the term 'FCAW-EH4' classification mean in AWS D1.1 Table 3.1?

    Answer: The electrode has a maximum diffusible hydrogen content of 4 mL/100g of deposited weld metal

    The 'H4' suffix in FCAW electrode classification indicates a maximum diffusible hydrogen content of 4 mL per 100 grams of deposited weld metal, the lowest hydrogen category.

  6. Under AWS D1.1, a complete joint penetration (CJP) groove weld is one that:

    Answer: Achieves fusion through the entire thickness of the joint

    A CJP groove weld fuses through the complete cross-sectional thickness of the joint, making the weld as strong as the base metal in tension across the joint.
