    What is the term given for the area of a welded joint outside the weld metal that has undergone microstructural changes?

    • Heat affected zone.

    • The weld zone

    • Fusion zone.

    • All of the above terms may be used.

    Correct Answer
    A. Heat affected zone.
    Explanation
    The term given for the area of a welded joint outside the weld metal that has undergone microstructural changes is the heat affected zone. This zone is affected by the heat from the welding process, causing changes in its microstructure and potentially altering its mechanical properties. The other options, such as the weld zone and fusion zone, do not specifically refer to the area outside the weld metal that has undergone microstructural changes. Therefore, the correct answer is heat affected zone.

    Under most conditions which of the following welding positions will deposit the most weld metal.

    • PG

    • PE

    • PC

    • PA

    Correct Answer
    A. PA
    Explanation
    In welding, different positions refer to the orientation of the welding joint. The PA position, also known as the flat position, is where the welding is done horizontally on a flat surface. This position allows for better control of the welding process, resulting in a higher deposition of weld metal. In contrast, the other positions (PG, PE, and PC) involve welding on vertical or overhead surfaces, which can be more challenging and may result in less weld metal being deposited. Therefore, under most conditions, the PA position will deposit the most weld metal.

    When measuring the welding parameters with the MMA welding process for the purpose of approving a welding procedure, the welding Inspector should measure the voltage:

    • As close to welding arc as possible.

    • Anywhere along the welding cable.

    • Always from the voltmeter on the welding plant.

    • As near to The welding terminals as possible.

    Correct Answer
    A. As close to welding arc as possible.
    Explanation
    When measuring the welding parameters with the MMA welding process for the purpose of approving a welding procedure, it is important for the welding inspector to measure the voltage as close to the welding arc as possible. This is because the voltage at the welding arc directly affects the quality and characteristics of the weld. By measuring the voltage at this point, the inspector can ensure that the welding parameters are within the specified range and that the welding procedure is being carried out correctly. Measuring the voltage anywhere along the welding cable or from the voltmeter on the welding plant may not provide an accurate representation of the voltage at the welding arc. Similarly, measuring the voltage as near to the welding terminals as possible ensures that the measurement is taken at the point where the welding current enters the workpiece.

    In an arc welding process, which of the following is the correct term used for the amount of weld metal deposited per minute?

    • Filling rate.

    • Deposition rate.

    • Weld deposition.

    • Weld duty cycle.

    Correct Answer
    A. Deposition rate.
    Explanation
    Deposition rate refers to the amount of weld metal that is deposited per minute in an arc welding process. It is a measure of the productivity and efficiency of the welding operation, indicating how quickly the weld joint is being filled. Filling rate, on the other hand, is not a commonly used term in welding and does not specifically refer to the amount of weld metal deposited. Weld deposition and weld duty cycle are also not the correct terms used for this measurement.

    Rate this question:

  • 7. 

    Which of the following butt-weld preparations is usually the most susceptible to lack of sidewall fusion during the manual arc process? 

    • A double-U butt

    • A single-V butt.

    • A double-V butt.

    • It is not normally a defect associated with the MMA welding process.

    Correct Answer
    A. A double-U butt
    Explanation
    A double-U butt weld preparation is usually the most susceptible to lack of sidewall fusion during the manual arc process. This is because the shape of the double-U butt creates a larger gap between the two pieces being welded, making it more difficult for the filler material to fully penetrate and fuse with the sidewalls. As a result, there is a higher likelihood of incomplete fusion and potential defects in the weld joint.

     What is the thickness of a fillet weld ( equal leg lengths )?

    • The distance from the toe to the face.

    • The distance from the root to the face centre.

    • The distance from the root to the toe.

    • The distance from toe to toe.

    Correct Answer
    A. The distance from the root to the face centre.
    Explanation
    The correct answer is the distance from the root to the face centre. In a fillet weld with equal leg lengths, the thickness is measured from the root, which is the point where the weld intersects the base metal, to the face centre, which is the midpoint of the weld. This measurement is important for determining the strength and integrity of the weld joint.

    Rate this question:

  • 9. 

    What is the leg length of a fillet weld?

    • The distance from the toe to face.

    • The distance from the root to the toe.

    • Its 0.7 of the design thickness.

    • Both b and c

    Correct Answer
    A. The distance from the root to the toe.
    Explanation
    The leg length of a fillet weld refers to the distance from the root to the toe. This measurement is important as it determines the strength and quality of the weld joint. The leg length affects the load-bearing capacity and resistance to stress of the weld. Therefore, it is crucial to ensure that the leg length is appropriate and meets the design specifications to ensure a strong and durable weld.

     What meant by the term crater pipe:

    • Another term for concave root.

    • Another term given for a burn through.

    • A type of gas pore found in the weld crater.

    • A shrinkage defect found in the weld crater.

    Correct Answer
    A. A shrinkage defect found in the weld crater.
    Explanation
    The term "crater pipe" refers to a shrinkage defect found in the weld crater. In welding, a crater is the depression or cavity at the end of a weld bead. During the solidification process, if there is insufficient molten metal to fill the crater, it can result in a defect called a crater pipe. This defect appears as a void or cavity within the weld crater, which can weaken the weld and potentially lead to failure. Therefore, the correct answer is A.

  • 11. 

    Which of the following is applicable for none planar defects?

    • They are always repaired.

    • Their existence will result in the removal of the entire weld.

    • They are not usually as significant as planar defects.

    • They can only be detected using radiograph .

    Correct Answer
    A. They are not usually as significant as planar defects.
    Explanation
    None planar defects are defects that do not occur in a straight line or plane within the weld. These defects can include things like porosity, undercutting, or convexity. The statement "They are not usually as significant as planar defects" suggests that none planar defects are generally considered to be less severe or less critical compared to planar defects. This implies that while none planar defects may still require repair, they are not as detrimental to the overall integrity and strength of the weld as planar defects would be.

    What is meant by the term weld junction?

    • The area containing the HAZ and weld metal.

    • The weld metal and parent metal.

    • The boundary between the fusion zone and the HAZ.

    • The part of the weld which has undergone metallurgical changes due to the heat from welding.

    Correct Answer
    A. The boundary between the fusion zone and the HAZ.
    Explanation
    The term "weld junction" refers to the boundary between the fusion zone and the Heat Affected Zone (HAZ). This is the area where the weld metal and parent metal meet, and it is characterized by metallurgical changes that occur as a result of the heat from welding. The weld junction is an important area to consider in welding as it can impact the strength and integrity of the weld.

    In the MMA welding process, which of the following is most likely to be caused by a welder with a poor technique? 

    • Deep weld craters/crater cracks.

    • Copper inclusions

    • Hydrogen cracks

    • All of the above

    Correct Answer
    A. Deep weld craters/crater cracks.
    Explanation
    Deep weld craters/crater cracks are most likely to be caused by a welder with a poor technique in the MMA welding process. This can occur when the welder does not properly control the welding parameters, such as the arc length, travel speed, or current. As a result, excessive heat may be applied to the base metal, leading to the formation of deep craters or cracks in the weld.

    Compound welds:

    • Always contain butt and fillet welds

    • joints which have combinations of welds made by different welding processes

    • Combinations between two different weld types

    • All of the above.

    Correct Answer
    A. Combinations between two different weld types
    Explanation
    The correct answer is "Combinations between two different weld types." Compound welds refer to joints that have combinations of welds made by different welding processes. This means that they can include both butt and fillet welds, as well as other combinations between two different weld types.

    Which of the following welding processes/technique is likely to be used for the repair welding of localised porosity in butt weld?

    • MMA, PG position.

    • Mechanised MAG.

    • Submerged arc.

    • None of the above.

    Correct Answer
    A. None of the above.
    Explanation
    None of the above options are suitable for the repair welding of localized porosity in a butt weld. MMA (Manual Metal Arc) welding is a manual process and may not provide the precision required for repairing localized porosity. Mechanized MAG (Metal Active Gas) welding is also not suitable as it is typically used for continuous welding of long seams, not for localized repairs. Submerged arc welding is a process where the arc is submerged under a layer of flux, and it is not ideal for repairing localized porosity. Therefore, none of the above options are appropriate for this specific repair welding task.

    18.    Which of the following is most likely to cause a burn through.

    • Root gap too small.

    • Travel speed too fast.

    • Root face too small.

    • All of the above.

    Correct Answer
    A. Root face too small.
    Explanation
    A burn through occurs when the heat input during welding is excessive, causing the metal to melt through the joint. In this case, a root face that is too small would result in a smaller gap between the two pieces of metal to be welded. This smaller gap would restrict the flow of heat away from the weld, leading to an increased heat concentration and a higher likelihood of burn through. Therefore, a root face that is too small is most likely to cause a burn through.

    Rate this question:

  • 17. 

    Root concavity is caused by:

    • Excessive back purge pressure and entrapped gas.

    • Excessive back purge pressure and very high heat inputs.

    • Excessive root grinding and a slow travel speed.

    • Excessive root grinding and excessive back purge pressure.

    Correct Answer
    A. Excessive root grinding and excessive back purge pressure.
    Explanation
    Excessive root grinding and excessive back purge pressure can cause root concavity. When the root is ground excessively, it removes too much material, resulting in a concave shape. Additionally, excessive back purge pressure can lead to the entrapment of gas, which can further contribute to root concavity. Therefore, both factors combined can cause this issue during the welding process.

    • The supervision of welders.

    • Procedure writing.

    • Qualifying welders.

    • All of the above.

    Correct Answer
    A. All of the above.
    Explanation
    A welding inspector's duties typically encompass overseeing welders, ensuring adherence to welding procedures, and qualifying welders according to established standards. They play a crucial role in maintaining quality and safety standards in welding operations, facilitating efficient and effective welding processes while mitigating potential risks and defects.

    The strength of a fillet weld is primary controlled by:

    • Leg length.

    • Design throat thickness.

    • Actual throat thickness.

    • All of the above.

    Correct Answer
    A. Design throat thickness.
    Explanation
    The strength of a fillet weld is primarily controlled by the design throat thickness. This refers to the theoretical thickness of the weld at its throat, which is the minimum distance between the root and face of the weld. The design throat thickness is determined by the size and shape of the weld, and it plays a crucial role in determining the overall strength and load-bearing capacity of the weld joint. Leg length and actual throat thickness are important factors in determining the quality and appearance of the weld, but they do not have as direct an impact on the strength as the design throat thickness.

    Rate this question:
