In which of these processes is acetylene used? oxyfuel cutting carbon are cutting flux core are welding gas tungsten arc welding

## Step 1<br />Acetylene is a type of hydrocarbon gas that is commonly used in welding and cutting processes. It is known for its high flame temperature, which makes it ideal for these applications.<br /><br />## Step 2<br />Among the options provided, acetylene is used in oxyfuel cutting. This process involves the use of a fuel gas, such as acetylene, and oxygen to cut metals. The high flame temperature of the acetylene-oxygen mixture is what allows it to cut through the metal.<br /><br />## Step 3<br />The other options, carbon arc cutting, flux core arc welding, and gas tungsten arc welding, do not typically use acetylene. These processes have different requirements and uses different gases.
