Oxy-acetylene is a welding process that uses a flame produced by burning a mixture of oxygen and acetylene gas. This high-temperature flame can reach temperatures of around 3,500 degrees Celsius (6,332 degrees Fahrenheit), making it suitable for cutting and welding metals. The equipment typically includes a gas cylinder for oxygen, a gas cylinder for acetylene, and a torch to mix and ignite the gases. This method is widely used in various industries, including construction and manufacturing, due to its versatility and effectiveness. Oxy-acetylene welding is particularly useful for joining thick materials and is often employed in tasks such as metal fabrication and repair work.
