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 process is commonly used in metal fabrication and repair work. In addition to welding, oxy-acetylene is also used for brazing and soldering, which involve joining metals without melting them. The equipment typically includes a gas cylinder for oxygen, a cylinder for acetylene, and a torch that mixes the gases to create the flame. Proper safety measures are essential when using this equipment.
