- 1.
Which of the following is not a correct statement about the oxy-acetylene welding process?
- A.
Acetylene is the fuel gas for the welding process
- B.
Acetylene cylinders contain porous material impregnated with acetone in which the acetylene is dissolved under pressure
- C.
Oxygen is a combustible gas which supports the combustion of acetylene under pressure
- D.
Acetylene cylinders have left-handed threads to prevent coupling with oxygen equipment
Correct Answer
C. Oxygen is a combustible gas which supports the combustion of acetylene under pressure -

What are the names of the 3 main flame types?
- A.
Carburising, Neutral & Reducing
- B.
Carburising, Neutral & Oxidising
- C.
Oxidising, Neutral & Reducing
- D.
Carburising, Oxidising & Reducing
Correct Answer
B. Carburising, Neutral & OxidisingExplanation
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.Rate this question:

It is safe to use matches when lighting a welding torch.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
It is not safe to use matches when lighting a welding torch. Welding torches require a high-intensity flame, which matches cannot provide. Instead, a welding torch should be ignited using a flint lighter or a spark lighter specifically designed for welding purposes. Using matches can lead to accidents or injuries due to the insufficient flame produced.Rate this question:

Highly flammable materials should be cleared from the work area for a radius of two metres when welding with oxy-acetylene equipment.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
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.Rate this question:

Using an excess (more/extra) acetylene is called a:
- A.
Oxidising flame
- B.
Carburising flame
- C.
Neutral flame
- D.
Hot flame
Correct Answer
B. Carburising flameExplanation
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:
