CSWIP 3.1- Model Paper-2 - Quiz

In this model paper for the certified scheme of welding inspectors, we’ll be asking you a whole host of questions regarding proper safety protocols and basic inspection knowledge to ensure you know how everything is supposed to operate. Do you know all there is to know? Take the quiz!


Questions and Answers
  • 1. 

    All things contain imperfections, but is only when they fall outside the level of acceptance they should be termed?

    • A.

      Discontinuity

    • B.

      Defect

    • C.

      Mechanical damage

    • D.

      Welding imperfections

    Correct Answer
    B. Defect
    Explanation
    Defects refer to imperfections that exceed the acceptable level. While all things have imperfections, only those that fall outside the acceptable range should be considered defects. This term is used to describe flaws or faults that affect the functionality, quality, or appearance of an object. It implies that the item does not meet the required standards or specifications.

    A singular gas filled cavity that is= or more than 1.6 mm in diameter is termed?

    • A.

      Cavity

    • B.

      Cluster porosity

    • C.

      Blow hole

    • D.

      Rounded porosity

    Correct Answer
    C. Blow hole
    Explanation
    A singular gas filled cavity that is equal to or more than 1.6 mm in diameter is termed a blow hole.

    Rate this question:

  • 3. 

    Lack of fusion imperfections are defined as?

    • A.

      Lack of union between two adjacent areas of material

    • B.

      Not cleaning out slag

    • C.

      Incorrect electrode manipulation in the final run

    • D.

      Incorrect set up

    Correct Answer
    A. Lack of union between two adjacent areas of material
    Explanation
    Lack of fusion imperfections refer to the absence of a proper bond between two adjacent areas of material. This means that there is a failure to achieve a complete fusion or joining of the materials, resulting in a lack of union. This can occur due to various factors such as improper welding techniques, inadequate heat input, or incorrect electrode manipulation. It is important to address these issues to ensure a strong and reliable weld.

  • 4. 

    What should happen to spatter before visual inspection is carried out?

    • A.

      Spatter is not a problem for visual inspection

    • B.

      Spatter that is more than 2 mm need not be cleaned for visual inspection

    • C.

      Spatter should be cleaned off before visual inspection

    • D.

      Spatter will not have any affect on the weld or the base material

    Correct Answer
    C. Spatter should be cleaned off before visual inspection
    Explanation
    Spatter should be cleaned off before visual inspection. This is because spatter, which refers to the unwanted bits of molten metal expelled during welding, can obstruct the view and make it difficult to properly assess the weld. Cleaning the spatter ensures a clear and accurate visual inspection of the weld and the base material.

    Rate this question:

  • 5. 

    Undercut can be defined as one of the following?

    • A.

      Concavity in the root of the weld

    • B.

      Crater in the fill of the weld

    • C.

      An oxide within the weld

    • D.

      Depression at the toe of the weld

    Correct Answer
    D. Depression at the toe of the weld
    Explanation
    Undercut refers to a depression or groove that forms at the toe of a weld. It is caused by excessive heat or improper welding technique, resulting in the melting away of the base metal. This depression weakens the weld joint and can lead to structural failure. Therefore, the correct definition of undercut in welding is a depression at the toe of the weld.

    Rate this question:

  • 6. 

    Excess penetration is often caused by which of the following?

    • A.

      Too high a welding current

    • B.

      Slow travel speed

    • C.

      Large root gap

    • D.

      All of the above

    Correct Answer
    D. All of the above
    Explanation
    Excess penetration in welding refers to the excessive depth of the weld pool, which can weaken the joint. It is caused by various factors, including too high a welding current, slow travel speed, and a large root gap. When the welding current is too high, it generates excessive heat, leading to excessive penetration. Similarly, a slow travel speed allows more time for the heat to be absorbed, resulting in deeper penetration. A large root gap creates a larger space for the molten metal to flow into, causing excessive penetration. Therefore, all of the above factors can contribute to excess penetration in welding.
