Whether it's a pipe, sheet, or something more complex, if there's a piece of steel, it's likely cut via the flame cutting process. More than a century old, this method involves using a high-temperature flame torch fueled with an oxy-fuel with at least 99.5% oxygen content. The other content can be a fuel gas like acetylene, propane, natural gas, or more. It's also known as oxyacetylene cutting or oxy-fuel cutting. If you're curious about this method, here's what you need to know.

What Is Flame Cutting?

As mentioned above, flame cutting uses a torch. On the torch, an outer ring sends off heat to preheat the surface to prepare it for the cut and prevent the surface from cracking. Then, a center ring shoots out a single flame that will cut the area. 

Flame cutting can be used to cut a wide range of steel thicknesses, from 1 mm to 1200 mm. No other process is as effective for cutting anything nearly that thick. However, it's important to note that under 20 mm, most steel fabricators prefer to use a laser cutter or waterjet machine. This is because those devices offer more precision. 

What Benefits Does It Provide?

Flame cutting is not only a tried and true process for cutting steel, but it's also one of the most cost-effective. The process itself has largely been unchanged since it was introduced more than a century ago. Because of this, it's also one of the most accessible methods. Aside from being the only method for thick steel, it's also suitable for large and wide surface areas. 

Furthermore, depending on the item, it's portable, and there are even CNC machines that can do the cutting. These are also known as "Computer Numerical Control" machines, and they can be programmed to make complex cuts. Flame cutting remains a versatile and reliable process; no matter the steel item, this method can get you what you need.
