    Select the correct welding process: - ProProfs

    Select the correct welding process:

    • MMA

    • MIG / MAG

    • TIG

    • SAW

    Correct Answer
    A. TIG
    Explanation
    TIG (Tungsten Inert Gas) welding is the correct welding process out of the given options. TIG welding uses a tungsten electrode to create an arc that melts the metal being welded, while an inert gas (usually argon) protects the weld area from atmospheric contamination. TIG welding is commonly used for precise and high-quality welds on thin materials, as it allows for better control over the heat input and produces clean and aesthetically pleasing welds.

    Rate this question:

  • 3. 

    Manual metal arc electrodes, stripped of flux, are being used as filler wire for TIG welding. You would object because:

    • The wire would be too thick

    • The wire is too short

    • It is too expensive

    • The weld metal composition may be wrong

    Correct Answer
    A. The weld metal composition may be wrong
    Explanation
    Using manual metal arc electrodes, stripped of flux, as filler wire for TIG welding can lead to incorrect weld metal composition. The composition of the electrode is specifically designed for manual metal arc welding, where the flux plays a crucial role in shielding the weld pool from atmospheric contamination. Without the flux, the weld metal may be exposed to impurities, resulting in an incorrect composition and potentially compromising the quality and strength of the weld. Therefore, using stripped electrodes as filler wire for TIG welding would not be advisable.

    Rate this question:

  • 4. 

    The steel composition in a structural contract is changed form 0.15% carbon, 0.6% manganese to 0.2% carbon, 1.2% manganese. Might this influence the incidence of:

    • Undercut for fillet welds

    • Cracking in the weld area

    • Lack of root fusion defects

    • Porosity

    Correct Answer
    A. Cracking in the weld area
    Explanation
    The increase in carbon and manganese content in the steel composition can lead to an increase in the susceptibility to cracking in the weld area. Higher carbon content can result in increased hardenability, making the steel more prone to cracking during the welding process. Similarly, higher manganese content can also contribute to the formation of brittle phases, which can further increase the risk of cracking. Therefore, the change in steel composition can potentially influence the incidence of cracking in the weld area.

    Rate this question:

  • 5. 

    Bend test specimens have been taken from a 25mm thick carbon steel butt weld. Which would show lack of inter-run fusion:

    • Face Bend

    • Guided Bend

    • Root bend

    • Side bend

    Correct Answer
    A. Side bend
    Explanation
    A side bend test specimen would show lack of inter-run fusion in a carbon steel butt weld. This is because a side bend test involves bending the specimen to examine the weld fusion along the side of the weld joint. If there is a lack of fusion between the different runs of the weld, it will be visible during the bending process. In contrast, a face bend test examines the fusion on the surface of the weld, a guided bend test examines the fusion at the root of the weld, and a root bend test examines the fusion at the root of the weld.

  • 6. 

    DWSI is a form of radiographic testing.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    DWSI stands for Double Wall Single Image. It is a radiographic testing technique used to inspect welds in pipes. In this method, the radiation source is placed outside the pipe, and the film is placed inside. The resulting radiograph shows a single image of the weld, even though the radiation has passed through both walls of the pipe. This technique is commonly used for pipes with diameters greater than 80mm.

    Rate this question:

  • 7. 

    If a welder is found to be working outside the parameters of the procedure the welding inspector is within his rights to revoke his approval?

    • True

    • False

    Correct Answer
    A. True
    Explanation
    If a welder is found to be working outside the parameters of the procedure, it means that they are not following the approved guidelines and specifications for welding. In such a case, the welding inspector has the authority to revoke the welder's approval. This is because working outside the set parameters can result in faulty welds, compromising the quality and integrity of the welded joints. The welding inspector's role is to ensure that all welders adhere to the approved procedures to maintain the highest standards of safety and quality in welding operations.

    Rate this question:

  • 8. 

    Which of the following elements has the greater effect on the hardenability of a steel plate?

    • Sulphur

    • Molybdenum

    • Carbon

    • Chromium

    Correct Answer
    A. Carbon
    Explanation
    Carbon has the greater effect on the hardenability of a steel plate compared to the other elements listed. Hardenability refers to the ability of a steel to be hardened through heat treatment. Carbon plays a crucial role in this process as it forms carbides, which are responsible for increasing the hardness of the steel. The higher the carbon content, the greater the hardenability of the steel. In contrast, while elements like sulphur, molybdenum, and chromium can also affect the properties of steel, they do not have as significant an impact on hardenability as carbon does.

    Rate this question:

  • 9. 

    Which gas shroud should be used when tungsten arc gas shielded welding aluminium alloys?

    • Nitrogen.

    • Carbon dioxide.

    • Argon/carbon dioxide mixture.

    • Argon.

    Correct Answer
    A. Argon.
    Explanation
    Argon is the recommended gas shroud for tungsten arc gas shielded welding of aluminium alloys. Argon is an inert gas that helps to create a protective atmosphere around the weld, preventing oxidation and contamination. It is commonly used for welding non-ferrous metals like aluminium because it does not react with the metal. Nitrogen and carbon dioxide are not suitable for this type of welding as they can cause porosity and other defects in the weld. An argon/carbon dioxide mixture may be used in some cases, but pure argon is generally preferred for welding aluminium alloys.

    Rate this question:

  • 10. 

     Which of the following defects would you not expect to find by visual inspection of welds? 

    • Overlap.

    • Linear misalignment.

    • Linear slag inclusions.

    • Undercut.

    Correct Answer
    A. Linear slag inclusions.
    Explanation
    Linear slag inclusions are not expected to be found by visual inspection of welds. Slag inclusions occur when molten slag becomes trapped in the weld metal during the welding process. However, linear slag inclusions are typically not visible on the surface of the weld and may require more advanced inspection techniques such as radiography or ultrasonic testing to detect. Therefore, they would not be expected to be identified through visual inspection alone.

    Rate this question:

  • 11. 

    Proof stress is used when non-ferrous metals are undergoing tensile tests to determine the equivalent Yield strength

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Proof stress is indeed used when non-ferrous metals are undergoing tensile tests to determine the equivalent Yield strength. During a tensile test, a non-ferrous metal is subjected to increasing tensile forces until it reaches its breaking point. The proof stress is the stress at which a material begins to exhibit permanent deformation, and it is an indicator of the yield strength of the material. By measuring the proof stress, one can determine the equivalent yield strength of the non-ferrous metal being tested. Therefore, the statement "Proof stress is used when non-ferrous metals are undergoing tensile tests to determine the equivalent Yield strength" is true.

    Spatter may be finely controlled during MIG / MAG welding by:

    • Increasing the arc voltage

    • Adjusting the inductance control

    • Welding with no gas

    • Using CO2 gas

    Correct Answer
    A. Adjusting the inductance control
    Explanation
    Adjusting the inductance control can help in finely controlling spatter during MIG / MAG welding. Inductance control refers to the adjustment of the inductance level in the welding machine. By adjusting this control, the welder can regulate the rate at which the welding current rises and falls. This can have an impact on the spatter produced during the welding process. By finding the right balance of inductance, the welder can minimize spatter and achieve a cleaner weld.

    The term used to describe weld metal refinement that occurs in a multi-run deposit is:

    • Weld annealing

    • Weld normalising

    • Weld refining

    • Weld recrystallisation

    Correct Answer
    A. Weld recrystallisation
    Explanation
    In multi-run welding, each subsequent weld pass introduces heat to the previously deposited weld metal. This heat can cause microstructural changes, including recrystallization. Recrystallization is a process where new, strain-free grains form within the existing weld metal, refining the grain structure and improving the mechanical properties of the weld. While the other options relate to heat treatment processes, they don't specifically describe the refinement process in multi-run welds.

    The most common type of defect found in a structure when it is undergoing service is:

    • Crystallisation.

    • Fatigue cracking.

    • Weld decay.

    • Stress fracture.

    Correct Answer
    A. Fatigue cracking.
    Explanation
    During the service life of a structure, it is subjected to repeated loading and unloading, which can lead to the development of fatigue cracking. Fatigue cracking occurs when the structure is exposed to cyclic stresses that are below the yield strength of the material but still cause damage over time. This type of defect is commonly found in structures due to the accumulation of small cracks that grow and propagate under repeated loading, eventually leading to failure if not addressed. Crystallisation, weld decay, and stress fracture are also types of defects but are less common compared to fatigue cracking.

    Rate this question:

  • 15. 

    Fatigue testing is used to test welds:

    • Under creep stress loading

    • Under cyclic loading

    • Under tensile loading

    • Under dynamic loading

    Correct Answer
    A. Under cyclic loading
    Explanation
    Fatigue testing is used to test welds under cyclic loading. This is because cyclic loading involves the application of repeated stress cycles to the weld, simulating real-life conditions where the weld may be subjected to fluctuating loads over time. Fatigue failure can occur when the weld is repeatedly stressed, leading to crack initiation and propagation. By subjecting the weld to cyclic loading in fatigue testing, its resistance to such failure can be evaluated, ensuring its durability and reliability in practical applications.

    If pipe bores are not matched correctly it can result in:

    • Overheating during welding.

    • Excessive root faces.

    • Incorrect gap setting.

    • Lack of root penetration.

    Correct Answer
    A. Lack of root penetration.
    Explanation
    If the pipe bores are not matched correctly, it can result in a lack of root penetration. This means that the weld does not fully penetrate the base metal, leading to a weak joint. This can compromise the structural integrity of the pipe, causing potential leaks or failures.

    Rate this question:

  • 17. 

    You have a macro section of a 'T' butt joint that shows a step-like defect lying outside the visible HAZ. What would this defect possibly signify? 

    • HAZ cracking.

    • Toe cracking.

    • Lamellar tearing.

    • Lamination.

    Correct Answer
    A. Lamellar tearing.
    Explanation
    A macro section of a 'T' butt joint that shows a step-like defect lying outside the visible HAZ indicates the presence of lamellar tearing. Lamellar tearing is a type of defect that occurs during the welding process when the steel plate has a high level of internal stress. These stresses can cause the material to tear along the grain boundaries, resulting in a step-like appearance. This defect is typically found outside the heat-affected zone (HAZ) and can weaken the joint, making it susceptible to failure under stress.

     Which of the following coatings is associated with stove welding? 

    • Rutile

    • Basic

    • Cellulosic

    • Oxidising

    Correct Answer
    A. Cellulosic
    Explanation
    Stove welding is a type of welding process that requires a coating on the electrode to provide protection and control the welding arc. The cellulosic coating is specifically designed for this purpose. It contains a high amount of cellulose, which creates a gas shield during welding that helps to stabilize the arc and protect the weld pool. This coating is commonly used for welding pipes and pressure vessels, as it produces a deep penetration and strong welds. The other coatings mentioned, such as rutile, basic, and oxidizing, are not typically associated with stove welding.

  • 19. 

    Which physical test is more likely to reveal HAZ embrittlement? 

    • Transverse tensile.

    • All weld tensile.

    • Root bend.

    • Charpy impact.

    Correct Answer
    A. Charpy impact.
    Explanation
    Charpy impact testing is more likely to reveal HAZ (Heat Affected Zone) embrittlement. HAZ embrittlement is a phenomenon that occurs in the heat-affected zone of a weld, where the material becomes brittle and prone to cracking. Charpy impact testing measures the impact energy absorbed by a material when subjected to a high-velocity impact, and it can detect the presence of embrittlement by measuring the decrease in impact energy. Transverse tensile and all weld tensile tests primarily measure the tensile strength of a material, while root bend tests assess the ductility and soundness of a weld.

    The unit of Joules would be used to measure: Tensile Strength?

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The unit of Joules would not be used to measure tensile strength. Tensile strength is measured in units of force per unit area, such as pounds per square inch (psi) or newtons per square meter (N/m^2). Joules, on the other hand, are used to measure energy or work done.

    Rate this question:

  • 21. 

    The property of a metal to return to its original shape is called ________. 

    Correct Answer
    Elasticity
    Explanation
    Elasticity refers to the property of a metal to return to its original shape after being deformed. When a force is applied to a metal, it undergoes temporary deformation, but once the force is removed, the metal regains its original shape. This ability to recover from deformation is known as elasticity. Elastic materials can stretch or compress under stress, but they will always return to their original form once the stress is released. This property makes metals highly useful in various applications where flexibility and resilience are required.

    Rate this question:

  • 22. 

    Which of the following welding processes uses a non-consumable electrode?

    • Shielded Metal Arc Welding (SMAW) 

    • Gas Metal Arc Welding (GMAW) 

    • Gas Tungsten Arc Welding (GTAW) 

    • Flux-Cored Arc Welding (FCAW)  

    Correct Answer
    A. Gas Tungsten Arc Welding (GTAW) 
    Explanation
    GTAW, also known as TIG (Tungsten Inert Gas) welding, uses a tungsten electrode that does not melt during the welding process. The arc is struck between the tungsten electrode and the workpiece, creating the heat needed to melt the base metal. A separate filler metal may be used to add material to the weld joint. In contrast, SMAW, GMAW, and FCAW all use consumable electrodes that melt and become part of the weld.

    Lamellar tearing has occurred in a steel fabrication. Before welding could it have been found by:

    • Dye penetrant

    • Ultrasonic inspection

    • It would not have been found by any inspection method

    • X-ray examination

    Correct Answer
    A. It would not have been found by any inspection method
    Explanation
    Lamellar tearing is a type of defect that occurs in steel fabrication due to the presence of non-metallic inclusions. These inclusions are difficult to detect using inspection methods such as dye penetrant, ultrasonic inspection, or X-ray examination. This is because the defect is not visible on the surface and cannot be detected using traditional non-destructive testing methods. Therefore, it would not have been found by any inspection method.

    Explanation
    Welder qualification tests focus on evaluating the welder's ability to apply their skills and knowledge to produce welds that meet specific quality standards. These tests assess the welder's technique, control, and understanding of the welding process. While welding procedures and material weldability are important factors, they are typically validated through separate procedure qualification tests and material testing, respectively.

    Rate this question:

  • 30. 

    Quenching a carbon or low alloy steel will result in an ________ in hardness and a ________   in ductility. 

    Correct Answer
    Increase
    Decrease
    Explanation
    Quenching involves rapidly cooling a heated metal, such as carbon or low alloy steel, in order to increase its hardness. The rapid cooling prevents the formation of large crystals, resulting in a harder material. However, this process also decreases the ductility of the steel, making it less able to withstand deformation without breaking. Therefore, quenching a carbon or low alloy steel will result in an increase in hardness and a decrease in ductility.
