Final answer:
Oxyfuel gas cutting and weld fabrication rely on the use of oxyhydrogen and oxyacetylene torches, which produce a high-temperature flame for cutting and welding metals. Acetylene is commonly used as the fuel gas, and liquid oxygen is used as the oxidizing agent for the combustion process.
Step-by-step explanation:
Oxyfuel gas cutting and weld fabrication rely on the use of oxyhydrogen and oxyacetylene torches. These torches use a combination of oxygen and a fuel gas such as acetylene to produce a high-temperature flame for cutting and welding metals.
Acetylene is commonly used as the fuel gas in oxyfuel gas cutting and weld fabrication. When the acetylene is mixed with oxygen and ignited, it produces a flame that can reach temperatures of up to 6,000 degrees Fahrenheit, making it suitable for cutting and welding metals.
Liquid oxygen is also important in the cutting and welding process, as it provides the necessary oxidizing agent for the combustion of the fuel gas.
