Oxy Fuel Cutting is a common metal cutting method used in manufacturing and construction. It's like using a very hot, precise torch to cut through thick metal. The process uses oxygen and fuel gas (usually propane or acetylene) to create a flame that heats metal and then uses a stream of pure oxygen to cut through it. This is one of the most basic and widely used methods for cutting thick metal plates and shapes. Other names for this process include "flame cutting," "gas cutting," or "torch cutting." It's particularly useful for cutting thick steel and is often used in shipyards, construction sites, and metal fabrication shops.
