Gas Welding Torches: A Crucial Tool for Welding Projects

What are the two types of torches used in gas welding?

1) Oxy-acetylene torch and Oxy-propane torch

2) Oxy-acetylene torch and Oxy-hydrogen torch

3) Oxy-hydrogen torch and Oxy-propane torch

4) Oxy-hydrogen torch and Acetylene torch

Final answer:

In gas welding, the two commonly used torches are the Oxy-acetylene torch and the Oxy-hydrogen torch.

Gas welding is a versatile and efficient method for joining metals. One of the key components of gas welding is the torch used to generate the heat necessary for melting the metals. The two main types of torches used in gas welding are the Oxy-acetylene torch and the Oxy-hydrogen torch.

The Oxy-acetylene torch functions by combusting acetylene gas in oxygen to produce a high-temperature flame that can melt and weld metal pieces together. This torch is commonly used in various welding applications due to its reliability and effectiveness.

On the other hand, the Oxy-hydrogen torch utilizes hydrogen gas as the combustible fuel, which is then combined with oxygen to create a flame capable of welding metals. This type of torch is preferred for certain welding projects that require a cleaner, hotter flame.

Both torches play a crucial role in gas welding processes, providing the heat needed to join metals together effectively. Additionally, the gaseous oxygen produced in these torch reactions has applications beyond welding, including in the space industry as an oxidizing agent in rocket engines and as a source of life support.
