Read the first 7 AWS Joint Design & Preparation flashcards as text

  1. When two plates of unequal thickness are joined in a butt joint under cyclic (fatigue) loading, AWS recommends tapering the thicker member. What is the maximum allowable taper slope per AWS D1.1?

    Answer: 1 in 5 (approximately 11°)

    AWS D1.1 limits the transition taper to a slope of 1 in 2-1/2 for static loading and 1 in 5 for cyclically loaded structures to minimize stress concentration.

  2. What is the primary purpose of specifying a root face (land) in a groove weld joint design?

    Answer: To provide a surface that resists burn-through and helps control root pass penetration

    The root face (land) provides a small area of base metal at the groove root that helps prevent burn-through while controlling penetration depth.

  3. A welder is preparing a double-V groove joint. Which advantage does this joint design offer over a single-V groove for the same plate thickness?

    Answer: It reduces the total weld metal volume and minimizes angular distortion

    A double-V groove uses roughly half the weld metal of a single-V and provides symmetric deposition that counteracts angular distortion.

  4. In groove weld joint design, what does 'CJP' stand for and what does it require?

    Answer: Complete Joint Penetration — the weld must fuse through the entire thickness of the joint

    CJP (Complete Joint Penetration) means the weld metal extends through the full thickness of the base metal, providing maximum joint strength.

  5. Which of the following groove angles is within the prequalified range for a single-V groove butt joint per AWS D1.1 when welding with SMAW?

    Answer: 60° included angle

    AWS D1.1 prequalified single-V groove joints require a minimum included angle of 60° for SMAW to ensure adequate access for the electrode.

  6. When designing a corner joint for sheet metal, which configuration produces the least distortion?

    Answer: Flanged corner joint with no additional weld metal

    A flanged corner (edge) joint formed by bending the sheet metal requires little to no added weld metal, minimizing heat input and distortion.

  7. What term describes the angular deviation from the specified dihedral angle of a fillet weld leg, and what is the AWS D1.1 maximum allowable convexity for a fillet weld with a 5/16-inch leg?

    Answer: Convexity; 1/16 inch maximum

    AWS D1.1 Table 8.1 limits fillet weld convexity to 1/16 inch for welds with legs up to 5/16 inch to prevent stress concentration at the weld toes.
