Question

Thermit welding is a form of:

• A. Resistance welding
• B. Gas welding
• C. Fusion welding
• D. Forge welding

Hint:

Thermit welding is ideal for high-temperature applications, such as welding steel and repairing rail tracks. Remember that it’s a fusion welding process, not a resistance or gas welding method.

Answer 1

The Correct Option is C

Thermit welding is a type of fusion welding that uses a chemical reaction between aluminum powder and iron oxide to produce molten metal. This process creates a very high temperature, allowing for the welding of metals by fusion. Thermit welding is often used for repairing rail tracks or for applications where high-temperature welding is required. Unlike resistance, gas, or forge welding, thermit welding relies on the exothermic reaction between metals to generate heat for fusion.
