    • E.

      Accept

    • F.

      Reject

    Correct Answer(s)
    C. Lack of sidewall fusion
    F. Reject
    Explanation
    The indication at position 4 is lack of sidewall fusion. Sidewall fusion refers to the proper bonding between the weld metal and the base metal along the sides of the weld joint. Lack of sidewall fusion indicates that there is a lack of proper bonding, which can weaken the weld and potentially lead to failure. Therefore, it is recommended to reject the indication to the given acceptance levels, as the lack of sidewall fusion does not meet the required standards for a quality weld.

    Correct Answer(s)
    C. Toe of the weld with poor transition
    F. Reject
    Explanation
    The indication at position 9 is the "toe of the weld with poor transition." This means that there is a defect in the welding where the weld transitions to the base material. Based on the given acceptance levels, this indication should be rejected as it does not meet the required quality standards.

    Rate this question:

  • 12. 

    Which term best describes this weld joint?

    • A.

      Square edge butt joint

    • B.

    • C.

      Single V butt joint

    • D.

      T butt fillet weld

    Correct Answer
    C. Single V butt joint
    Explanation
    A single V butt joint is a type of weld joint where two pieces of metal are joined together by a V-shaped groove. The groove is created by cutting a V-shaped notch in the edges of the metal pieces, allowing for a stronger and more secure weld. This type of joint is commonly used for thicker materials and provides better penetration and fusion between the pieces.

    • D.

      Polished area

    Correct Answer
    A. Heat affected zone
    Explanation
    The area identified at position 8 is the heat affected zone. This is the region of a material that has undergone changes in its microstructure due to the heat generated during welding or other high-temperature processes. The heat affected zone is characterized by altered mechanical properties and can be prone to cracking or other defects. It is distinct from the fusion zone, which is the area where the base metal has melted and fused together, and from the fusion boundary, which marks the transition between the base metal and the weld metal. The polished area is not relevant to the identification of the specific zone.

    The indication at position 10 is porosity. Porosity refers to the presence of small voids or gas pockets in a material. In this case, the indication of porosity is being observed. The question asks whether we would accept or reject this indication to the given acceptance levels. Since the answer is "accept," it implies that the level of porosity observed at position 10 is within the acceptable range and does not pose any significant issues or defects in the material.

    The area identified at position 1 is the?

    • A.

      Square edge butt

    • B.

      Double V butt joint

    • C.

      Single V butt joint

    • D.

      T butt fillet weld

    Correct Answer
    C. Single V butt joint
    Explanation
    The area identified at position 1 is a single V butt joint. This type of joint is created by beveling the edges of two pieces of metal to form a V shape and then welding them together. The V shape helps to create a strong and durable joint by increasing the surface area for the weld. This type of joint is commonly used in structural welding applications where strength is important.
