  1. What does the 'E' dimension in parentheses on a groove weld symbol represent?

    Answer: The effective throat

    The parenthetical 'E' dimension on a groove weld symbol represents the effective throat, while the number without parentheses indicates the groove depth.

  2. The effective throat of a fillet weld is measured from:

    Answer: The root to the hypotenuse, measured perpendicularly

    The effective throat of a fillet weld is the perpendicular distance from the root to the hypotenuse of the largest inscribed right triangle in the weld cross section.

  3. For an equal-leg fillet weld with a leg size of 3/8 inch, the theoretical throat is approximately:

    Answer: 0.265 inch

    The theoretical throat equals the leg size multiplied by 0.707, so 3/8 × 0.707 ≈ 0.265 inch.

  4. A groove weld with complete joint penetration (CJP) means:

    Answer: The weld metal completely penetrates through the entire thickness of the joint

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

  5. Which groove weld type can achieve full penetration on thin material without a root opening when welded from both sides?

    Answer: Square groove weld

    A square groove weld on thinner materials may be welded from both sides without a root opening when the material is thin enough for full penetration.

  6. The size of a fillet weld is specified as the:

    Answer: Length of the weld leg

    The size of a fillet weld is specified by the leg length of the largest right triangle that can be inscribed within the fillet weld cross section.
