Which of the following butt-weld preparations is usually the most susceptible to lack of sidewall fusion during the manual arc process?
- A.
A double-U butt
- B.
A single-V butt.
- C.
A double-V butt.
- D.
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 double-U shape creates a larger gap between the two pieces of metal, making it more difficult for the welder to ensure complete fusion along the sidewalls. The shape of the double-U butt weld requires precise control and manipulation of the welding arc to ensure proper fusion, which can be challenging during manual arc welding.Rate this question:

What is the leg length of a fillet weld?
- A.
The distance from the toe to face.
- B.
The distance from the root to the toe.
- C.
Its 0.7 of the design thickness.
- D.
Both b and c
Correct Answer
B. 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 integrity of the weld. A proper leg length ensures that the weld can withstand the intended load and prevents any potential weaknesses or failures. The distance from the root to the toe is therefore the correct answer in this case.Rate this question:

What is the thickness of a fillet weld ( equal leg lengths )?
- A.
The distance from the toe to the face.
- B.
The distance from the root to the face centre.
- C.
The distance from the root to the toe.
- D.
The distance from toe to toe.
Correct Answer
B. The distance from the root to the face centre.Explanation
The thickness of a fillet weld with equal leg lengths is measured as the distance from the root to the face center. This means that the measurement starts from the root of the weld, which is the point where the weld begins, and extends to the center of the face of the weld. This measurement is important in determining the strength and integrity of the weld joint.Rate this question:

Compound welds:
- A.
Always contain butt and fillet welds
- B.
joints which have combinations of welds made by different welding processes
- C.
Combinations between two different weld types
- D.
All of the above.
Correct Answer
C. Combinations between two different weld typesExplanation
The correct answer is "Combinations between two different weld types." Compound welds refer to joints that involve a combination of different types of welds, such as butt and fillet welds made by different welding processes. This means that compound welds can include a variety of weld types, making the answer "All of the above" incorrect as it implies that compound welds always contain both butt and fillet welds.Rate this question:

A duty not normally undertaken by a welding inspector is to:
- A.
Check the condition of the parent material.
- B.
Check the condition of the consumables.
- C.
Measure residual stress.
- D.
Check calibration certificates.
Correct Answer
C. Measure residual stress.Explanation
A welding inspector's primary duty is to ensure the quality and integrity of welds. This involves inspecting the condition of the parent material and consumables, as well as checking calibration certificates to ensure accurate measurements. However, measuring residual stress is not typically within the scope of a welding inspector's responsibilities. Residual stress is typically measured by specialized technicians using specific equipment and techniques, as it requires a deeper understanding of materials science and engineering.Rate this question:

Under most conditions which of the following welding positions will deposit the most weld metal.
- A.
PG
- B.
PE
- C.
PC
- D.
PA
Correct Answer
D. PAExplanation
In welding, the position that deposits the most weld metal is the PA position. This position refers to the flat position where the welding is done from the upper side of the joint. In this position, gravity helps to pool the weld metal, resulting in a higher deposition rate. The other positions mentioned (PG, PE, PC) are not as conducive to depositing large amounts of weld metal.Rate this question:

What meant by the term crater pipe:
- A.
Another term for concave root.
- B.
Another term given for a burn through.
- C.
A type of gas pore found in the weld crater.
- D.
A shrinkage defect found in the weld crater.
Correct Answer
D. A shrinkage defect found in the weld crater.Explanation
The term "crater pipe" refers to a shrinkage defect found in the weld crater. A weld crater is the depression or cavity that is formed at the end of a weld joint. When the weld solidifies, it can sometimes result in shrinkage, causing a defect known as a crater pipe. This defect can weaken the weld and compromise its integrity. Therefore, the correct answer is that a crater pipe is a shrinkage defect found in the weld crater.Rate this question:
-

What is meant by the term weld junction?
- A.
The area containing the HAZ and weld metal.
- B.
The weld metal and parent metal.
- C.
The boundary between the fusion zone and the HAZ.
- D.
The part of the weld which has undergone metallurgical changes due to the heat from welding.
Correct Answer
C. 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 base metal has been fused together with the weld metal. The fusion zone is the portion of the weld where the base metal and filler metal have melted and mixed together, while the HAZ is the area surrounding the fusion zone that has experienced metallurgical changes due to the heat from welding. Therefore, the correct answer is "The boundary between the fusion zone and the HAZ."Rate this question:

The strength of a fillet weld is primary controlled by:
- A.
Leg length.
- B.
Design throat thickness.
- C.
Actual throat thickness.
- D.
All of the above.
Correct Answer
B. Design throat thickness.Explanation
The strength of a fillet weld is primarily controlled by the design throat thickness. The design throat thickness is the theoretical minimum thickness of the weld, calculated based on the geometrical properties of the joint. It represents the effective area of the weld that contributes to its strength. Leg length refers to the distance from the root of the weld to the toe, and while it affects the size of the weld, it does not directly control its strength. Actual throat thickness refers to the measured thickness of the weld, which may vary from the design throat thickness due to welding process variables. Therefore, the correct answer is design throat thickness.Rate this question:

Which of the following is applicable for none planar defects?
- A.
They are always repaired.
- B.
Their existence will result in the removal of the entire weld.
- C.
They are not usually as significant as planar defects.
- D.
They can only be detected using radiograph .
Correct Answer
C. They are not usually as significant as planar defects.Explanation
None planar defects refer to defects that are not in a flat or planar form, such as porosity or undercut. These defects are generally less significant compared to planar defects like cracks or lack of fusion. While they may still affect the integrity of the weld, they are usually easier to repair or may not require the removal of the entire weld. Therefore, the statement "They are not usually as significant as planar defects" is applicable for none planar defects.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?
- A.
MMA, PG position.
- B.
Mechanised MAG.
- C.
Submerged arc.
- D.
None of the above.
Correct Answer
D. 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. PG position refers to the position of the weld, not the welding process itself. Mechanised MAG (Metal Active Gas) welding and submerged arc welding are both commonly used for joining large structures and are not typically used for repairing localized porosity. Therefore, none of the above options are likely to be used for this specific repair welding task.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:
- A.
As close to welding arc as possible.
- B.
Anywhere along the welding cable.
- C.
Always from the voltmeter on the welding plant.
- D.
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 welding procedure is being performed correctly and that the appropriate voltage is being applied to create a strong and reliable weld. Measuring the voltage anywhere along the welding cable or always from the voltmeter on the welding plant may not accurately reflect the conditions at the welding arc. Similarly, measuring the voltage as near to the welding terminals as possible may not provide an accurate measurement of the voltage at the welding arc.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?
- A.
Deep weld craters/crater cracks.
- B.
Copper inclusions
- C.
Hydrogen cracks
- D.
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 is because deep weld craters occur when the welder does not properly control the welding current and allows excessive heat to accumulate in one area, leading to the formation of a deep crater. Crater cracks can then occur when the welder does not properly fill in the crater, resulting in a weak point in the weld.Rate this question:

Root concavity is caused by:
- A.
Excessive back purge pressure and entrapped gas.
- B.
Excessive back purge pressure and very high heat inputs.
- C.
Excessive root grinding and a slow travel speed.
- D.
Excessive root grinding and excessive back purge pressure.
Correct Answer
D. Excessive root grinding and excessive back purge pressure.Explanation
Excessive root grinding can cause root concavity because it removes too much material, creating a depression in the root. Excessive back purge pressure can also contribute to root concavity because it can push gas into the weld, causing trapped gas pockets that can lead to concavity. Therefore, the combination of both excessive root grinding and excessive back purge pressure can result in root concavity.Rate this question:

When inspecting a critical component, the toes of a weld must be:
- A.
Always ground flush.
- B.
Must always overlap at least 1.5 mm onto the parent material.
- C.
Must always be inspected using a crack detection method ( MPI,DPI ).
- D.
None of the above can be selected – specification requirements unknown
Correct Answer
D. 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 standard for the toes of a weld when inspecting a critical component. Without knowing the specification requirements, we cannot determine how the toes of the weld should be treated or inspected.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?
- A.
Carry out normal visual inspection.
- B.
Seek advice from higher authority.
- C.
Carry out visual inspection.
- D.
Re–write the requirements of the specification.
Correct Answer
B. Seek advice from higher authority.Explanation
In this situation, since the specification does not provide any requirements for visual inspection, it is important to seek advice from a higher authority. This is necessary to ensure that the visual inspection is carried out correctly and in accordance with the appropriate guidelines or standards. By seeking advice from a higher authority, you can obtain the necessary guidance and clarification on how to proceed with the visual inspection in the absence of specific requirements in the specification.Rate this question:

Under most circumstances, which of the following do you consider to be duties of a welding inspector?
- A.
The supervision of welders.
- B.
Procedure writing.
- C.
Qualifying welders.
- D.
All of the above.
Correct Answer
C. Qualifying welders.Explanation
Qualifying welders is considered a duty of a welding inspector because it involves assessing the skills and capabilities of welders to ensure they meet the necessary standards and qualifications for performing welding tasks. This includes evaluating their knowledge of welding techniques, understanding of safety procedures, and ability to produce quality welds. By qualifying welders, a welding inspector helps to maintain the integrity and safety of welding operations. Supervision of welders and procedure writing may also be responsibilities of a welding inspector, but the question specifically asks for the duty that is applicable under most circumstances, making qualifying welders the most appropriate answer.Rate this question:

18. Which of the following is most likely to cause a burn through.
- A.
Root gap too small.
- B.
Travel speed too fast.
- C.
Root face too small.
- D.
All of the above.
Correct Answer
C. Root face too small.Explanation
A burn through occurs when the heat input during welding is too high, causing the metal to melt completely through the joint. A root face refers to the distance between the root of the joint and the surface of the base metal. If the root face is too small, it means that the joint is too close to the surface, resulting in a higher heat concentration and increased likelihood of burn through. Therefore, a root face that is too small is the most likely factor to cause a burn through.Rate this question:

- D.
Weld duty cycle.
Correct Answer
B. Deposition rate.Explanation
The correct term used for the amount of weld metal deposited per minute in an arc welding process is the deposition rate. This refers to the rate at which the weld metal is added to the workpiece during the welding process. It is an important parameter that determines the efficiency and productivity of the welding operation. The deposition rate can be controlled by adjusting the welding parameters such as current, voltage, and travel speed.Rate this question:

What is the term given for the area of a welded joint outside the weld metal that has undergone microstructural changes?
- A.
Heat affected zone.
- B.
The weld zone
- C.
Fusion zone.
- D.
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 generated during the welding process, which can cause changes in the material's microstructure and properties. The weld zone refers specifically to the area where the weld metal is located, and the fusion zone refers to the area where the base metal and weld metal have fused together. However, the heat affected zone is the specific term used to describe the area outside the weld metal that has experienced these microstructural changes.Rate this question:
