Define oxyfuel gas welding.

Oxyfuel gas welding is a welding process that uses a combination of oxygen and a fuel gas, such as acetylene, propane, or natural gas, to create a high-temperature flame that melts and joins metal pieces together. The fuel gas is mixed with oxygen in a welding torch, and the resulting flame is directed onto the workpiece to create a weld. Oxyfuel gas welding is commonly used for welding thin metal sheets and pipes in industries such as construction, automotive, and manufacturing.

Oxyfuel Gas Welding is a welding process that uses the combustion of two gases, oxygen and a fuel gas, to produce a high-temperature flame that melts the metal at the joint. The oxygen is typically supplied from a cylinder or tank, while the fuel gas can be acetylene, propane, or other combustible gases. The gases are mixed in the torch, where they are ignited and burned, producing a flame that is directed at the joint to be welded. The melted metal flows together, forming a strong bond between the two pieces of metal.
