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, such as grain growth and hardness variations. The weld zone refers specifically to the area where the weld metal is located, and the fusion zone refers to the region where the base metal and the weld metal have fused together. Therefore, the correct term for the given description is the heat affected zone.Rate this question:

Under most conditions which of the following welding positions will deposit the most weld metal.
-
PG
-
PE
-
PC
-
PA
Correct Answer
A. PAExplanation
In welding, the position of the weld refers to the orientation of the joint relative to the ground. PA stands for "flat position," where the weld is performed horizontally. In this position, the weld metal is deposited directly onto the joint, resulting in a higher deposition rate compared to other positions. This is because the weld pool is more stable, allowing for better control and a higher volume of weld metal to be deposited. Therefore, under most conditions, the PA position will deposit the most weld metal.Rate this question:

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 is the correct term used for the amount of weld metal deposited per minute in an arc welding process. It refers to the rate at which the filler metal is added to the joint during welding. This term is important in determining the productivity and efficiency of the welding process, as it indicates how quickly the weld can be completed and how much material is being added. The deposition rate can vary depending on factors such as the welding technique, welding parameters, and the type and size of the filler metal being used.Rate this question:

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 buttExplanation
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 of metal, making it more difficult for the heat and filler metal to reach the sidewalls and fuse them together properly. As a result, there is a higher risk of incomplete fusion and potential defects in the weld joint.Rate this question:

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, 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 of the weld. By measuring the voltage at this point, the inspector can ensure that the correct voltage is being used for the welding procedure, which is crucial for approving the welding procedure. 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 may not accurately reflect the voltage at the welding arc.Rate this question:

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 in determining the strength and integrity of the weld joint. The root is the deepest part of the weld, while the toe is the outer edge. By measuring the distance between these two points, one can assess the quality and effectiveness of the weld. The other options provided in the question, such as the distance from the toe to face and 0.7 of the design thickness, are not accurate descriptions of the leg length of a fillet weld.Rate this question:

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 center, which is the middle point of the weld. This measurement determines the overall thickness of the weld and is important for ensuring the strength and integrity of the joint.Rate this question:

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 that forms at the end of a weld bead. During the solidification process, if there is insufficient molten metal to fill the crater, a shrinkage defect can occur, resulting in a void or pipe-like structure in the weld crater. This defect can weaken the weld and compromise its integrity. Therefore, "crater pipe" is used to describe this specific type of shrinkage defect found in the weld crater.Rate this question:

When carrying out visual inspection, the specification makes no mention of the requirements for visual inspection, in this situation what shroud you do?
-
Carry out normal visual inspection.
-
Seek advice from higher authority.
-
Carry out visual inspection.
-
Re–write the requirements of the specification.
Correct Answer
A. Seek advice from higher authority.Explanation
In this situation where the specification does not mention the requirements for visual inspection, it is important to seek advice from a higher authority. This is because the lack of specific instructions can lead to ambiguity and uncertainty regarding the correct procedure for visual inspection. By consulting with a higher authority, one can obtain guidance and clarification on how to proceed with the inspection in a way that aligns with the overall requirements and objectives.Rate this question:

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 not usually as significant as planar defects. This means that while they may still affect the integrity of the weld, they are generally considered to be less serious or less critical. Planar defects, on the other hand, refer to defects that occur in a two-dimensional plane, such as cracks or lack of fusion, and are typically more severe and require immediate repair or removal of the entire weld.Rate this question:

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. This is because deep weld craters occur when the welder does not properly control the welding arc and allows it to dwell in one spot for too long, resulting in excessive heat input. This can lead to the formation of a deep crater, which is prone to cracking. Therefore, a welder with poor technique is more likely to cause deep weld craters/crater cracks compared to copper inclusions or hydrogen cracks.Rate this question:

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 boundary represents the transition area where the weld metal and the surrounding parent metal meet. It is at this junction that the metallurgical changes occur due to the heat generated during the welding process. The weld junction is an important area to consider in welding as it can affect the overall strength and integrity of the weld.Rate this question:

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 root face, which is the gap between the two pieces being welded, is too small. This can lead to excessive heat being concentrated in a small area, causing the metal to melt and burn through. A root gap that is too small or a travel speed that is too fast can also contribute to burn through, but the most likely cause is a root face that is too small.Rate this question:

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 typesExplanation
The correct answer is "Combinations between two different weld types." This means that compound welds are formed by combining two different types of welds. This could include a combination of butt and fillet welds, or joints made by different welding processes. Therefore, compound welds always involve a mixture of different weld types.Rate this question:

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. The design throat thickness refers to the theoretical minimum thickness of the weld, which is calculated based on the size of the weld and the angle between the two joining surfaces. It is an important factor in determining the load-carrying capacity of the weld joint. Leg length and actual throat thickness may also have some influence on the strength of the weld, but the design throat thickness is the most significant factor.Rate this question:

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
The correct answer is "None of the above" because none of the mentioned welding processes/techniques are suitable for repairing localized porosity in a butt weld. MMA (Manual Metal Arc) and Mechanised MAG (Metal Active Gas) are not ideal for repairing porosity as they do not provide sufficient control over the welding process. Submerged arc welding is also not suitable as it is typically used for deep penetration and high deposition rate, which may not be necessary for repairing localized porosity. Therefore, an alternative welding process or technique would need to be used for this specific repair.Rate this question:

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
Root concavity refers to a depression or indentation at the root of a weld joint. This defect is caused by excessive root grinding, which removes too much material and creates a gap between the base metal and the weld metal. Additionally, excessive back purge pressure can push gas into this gap, further exacerbating the concavity. Therefore, the correct answer is that root concavity is caused by both excessive root grinding and excessive back purge pressure.Rate this question:

When inspecting a critical component, the toes of a weld must be:
-
Always ground flush.
-
Must always overlap at least 1.5 mm onto the parent material.
-
Must always be inspected using a crack detection method ( MPI,DPI ).
-
None of the above can be selected – specification requirements unknown
Correct Answer
A. None of the above can be selected – specification requirements unknownExplanation
The correct answer is "None of the above can be selected – specification requirements unknown." This means that there is no specific requirement or guideline regarding the toes of a weld when inspecting a critical component. The specification requirements are unknown, so it is not possible to determine what should be done with the toes of the weld.Rate this question:
