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 & 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.
-
True
-
False
Correct Answer
A. 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.
-
True
-
False
Correct Answer
A. 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:
-
Oxidising flame
-
Carburising flame
-
Neutral flame
-
Hot flame
Correct Answer
A. 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:
