Oxy Fuel Flame Cutting Services

Oxy fuel flame cutting-also referred to as oxyacetylene cutting, oxy cutting, and flame cutting-is a thermal cutting process that leverages the chemical reaction between pure oxygen and steel to cut material into the desired size and shape. It is an effective and efficient method of cutting steel and iron in thicknesses ranging from 0.25-12 inches.

At Accurate Metal Products (AMP), we offer oxy fuel flame cutting services. Armed with over two decades of industry experience and state-of-the-art equipment, our team has the knowledge, skills, and tools to precision flame cut parts suitable for use in a diverse set of industries.

Below we outline the basic steps of the process, typical applications, how it compares to alternative cutting methods, and our capabilities.

An Overview of the Oxy Fuel Flame Cutting Process

As mentioned above, oxy fuel cutting involves a chemical reaction between oxygen and steel. This reaction results in rapid—but controlled—rusting of the workpiece in localized areas, which, when removed, forms cavities in the workpiece. As the reaction spreads across the workpiece, the cavities merge into a continuous cut.

The stages of an oxy fuel cutting operation are as follows:

  1. A combination of oxygen and fuel gas (e.g., acetylene, propane, or MAPP) is used to heat the metal to its ignition point but below its melting point. For steel, this point is 700–900° C.
  2. A stream of pure oxygen is aimed at the preheated area, which initiates an exothermic reaction between the oxygen and workpiece that forms iron oxide.
  3. The continued application of oxygen blows the iron oxide away, enabling the stream to eventually pierce through and cut the workpiece as it moves across the surface.

Industrial Applications

Oxy fuel flame cutting is an ideal method of producing steel and iron components for use in many industries. Below we outline some of the industries we serve with our oxy fuel flame cutting capabilities and project examples:

  • Electrical: The high cutting precision offered by the oxy fuel cutting process enabled us to create a steel rotor intended for use as part of a braking system for heavy electrical machinery.
  • Energy: We used a combination of oxy fuel cutting and machining to create a steel crankshaft counterweight for a power generation application.
  • Manufacturing: The precision and power of the oxy fuel flame cutting process allowed us to produce a custom steel drive ring for a rock crushing application.
  • Mining: We created a large bearing cap made of A36 steel for surface mining equipment using oxy flame cutting.

Oxy Fuel Flame Cutting vs. Plasma Cutting

Oxy fuel flame cutting and plasma cutting are commonly employed by industry professionals to cut metal to the desired shape and size. Some of the primary distinctions between the two cutting methods are:

  • Oxy fuel flame cutting uses a stream of pure oxygen to cause a chemical reaction with the workpiece that results in the formation of a kerf, while plasma cutting employs a stream of ionized gas (i.e., plasma) to melt the workpiece and form a cut.
  • Oxy fuel flame cutting is suitable for iron and steel, while plasma cutting is more effective at cutting conductive and more corrosion-resistant metals, such as aluminum and stainless steel.
  • Oxy fuel flame cutting is better at cutting thicker materials, while plasma cutting is better at producing cuts on angled surfaces.
