    What are the names of the 3 main flame types?

    • Carburising, Neutral & Reducing

    • Carburising, Neutral & Oxidising

    • Oxidising, Neutral & Reducing

    • Carburising, Oxidising & Reducing

    Correct Answer
    A. Carburising, Neutral & Oxidising
    Explanation
    The three main flame types are carburising, neutral, and oxidising. Carburising flame is used to introduce carbon into the surface of a metal, neutral flame does not introduce any elements into the metal, and oxidising flame introduces oxygen into the metal to promote oxidation.

  • 3. 

    Using an excess (more/extra) acetylene is called a:

    • Oxidising flame

    • Carburising flame

    • Neutral flame

    • Hot flame

    Correct Answer
    A. Carburising flame
    Explanation
    In the process of carburization, excess acetylene is used to introduce carbon into the surface of a material, typically steel, to increase its hardness. This is done by heating the material in a fuel-rich environment, where the excess acetylene reacts with the heated metal to form carbon compounds. This creates a carburizing flame, which is characterized by an excess of fuel (acetylene) and a reducing atmosphere. The carbon introduced into the material enhances its strength and wear resistance. Therefore, the correct answer is "Carburising flame."

    Rate this question:

  • 4. 

    Which of the following is not a correct statement about the oxy-acetylene welding process?

    • Acetylene is the fuel gas for the welding process

    • Acetylene cylinders contain porous material impregnated with acetone in which the acetylene is dissolved under pressure

    • Oxygen is a combustible gas which supports the combustion of acetylene under pressure

    • Acetylene cylinders have left-handed threads to prevent coupling with oxygen equipment

    Correct Answer
    A. Oxygen is a combustible gas which supports the combustion of acetylene under pressure
  • 5. 

    Highly flammable materials should be cleared from the work area for a radius of two metres when welding with oxy-acetylene equipment.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    Highly flammable materials should be cleared from the work area for a radius of two metres when welding with oxy-acetylene equipment. This statement is false. When welding with oxy-acetylene equipment, highly flammable materials should be cleared from the work area for a radius of at least 10 meters. This is because the welding process produces sparks, heat, and flames that can easily ignite flammable materials and cause a fire hazard. Therefore, it is important to maintain a safe distance to prevent accidents and ensure the safety of the work environment.
