Welcome to our blog post on the differences between oxyfuel and plasma cutting technology. There are various methods of cutting metal in the steel processing industry, and oxyfuel and plasma cutting technologies are among the most commonly used processes. In this article, we will highlight the basic differences between oxyfuel and plasma cutting technology to help you choose the right cutting method for your needs.
- Operating principle:
The fundamental difference between oxyfuel and plasma cutting technology lies in the principle of operation. Oxyfuel cutting technology uses a heating flame generated by the combustion of oxygen and a fuel gas. This heating flame generates high temperatures that melt the metal. Once the metal is melted, additional oxygen is added with pressure. This additional oxygen is called cutting oxygen, because it reacts with the carbon contained in the steel and produces the so-called cutting flame. As a result, the steel is literally „burned through“. Plasma cutting technology, on the other hand, generates a plasma jet by passing an electrically conductive gas through an arc between an electrode and the workpiece. The plasma jet melts the metal and a separate compressed air flow removes the melt from the kerf.
Oxyfuel and plasma cutting technologies have different applications. Oxyfuel cutting technology is well suited for cutting thicker metals, especially carbon steel. It can also be used for cutting aluminum and stainless steel, but requires special gases and equipment. Plasma cutting technology, on the other hand, is more versatile and can cut a wider range of materials, including aluminum, stainless steel, copper and other non-ferrous metals.
- Cutting speed and accuracy:
Another difference lies in the cutting speed and accuracy of the two cutting technologies. Plasma cutting machines are typically faster than oxyfuel cutting machines and allow for more efficient production. Plasma cutting technology also offers higher precision and enables cutting of complex shapes and fine details. Oxyfuel cutting technology, on the other hand, is typically slower and less precise, making it suitable for applications that do not have high accuracy requirements.
- Material thickness:
Material thickness is an important factor in choosing the appropriate cutting technology. Oxyfuel cutting technology is particularly effective with thicker materials because it generates high temperatures and melts the metal. Plasma cutting technology, on the other hand, can cut a wider range of material thicknesses, from thin sheets to thicker plates.
- Costs and operating expenses:
Cost and operational overhead are also differences to consider between the two technologies. Oxyfuel cutting technology requires the use of cylinder gases and additional equipment, which can result in higher operating costs. Plasma cutting technology requires the use of plasma gas and regular maintenance of wear parts. However, it should be noted that advanced plasma cutting technology is becoming increasingly energy efficient and uses less expensive gases.
The choice between oxyfuel and plasma cutting technology depends on several factors, including the application area, material thickness, desired cutting speed and accuracy, and cost. Oxyfuel cutting technology is good for thicker materials, while plasma cutting technology is more versatile and precise.
