OxyFuel Cutting Steel And Cast Iron

This article discusses a few hands on tips to keep in mind while performing oxyfuel cutting of steel and cast iron. General Cutting of carbon steels can be easily done with an oxy-fuel torch. The low carbon steels containing less than 0.25% carbon do not pose much problem. However, for cutting of medium carbon and high carbon … Read more

Oxy-Acetylene Cutting

This article starts with an overview of oxy-fuel cutting overview, and proceeds to explain in detail about the oxy-acetylene cutting process. Oxy-Fuel Cutting Overview (1) If iron or steel is heated to its kindling temperature (not less than 1600°F (871°C)), and is then brought into contact with oxygen, it burns or oxidizes very rapidly. The … Read more

Air Carbon Cutting (AAC)

Air carbon cutting is an arc cutting process in which metals to be cut are melted by the heat of a carbon arc. The molten metal is removed by a blast of air. This is a method for cutting or removing metal by melting it with an electric arc and then blowing away the molten metal … Read more

OxyFuel Cutting with MAPP Gas

While cutting with acetylene is more common, oxyfuel cutting with MAPP gas can be used with equally good results as well. Cutting with MAPP gas is similar to cutting with acetylene gas in combination with oxygen. This article discusses a few differences. Cutting With MAPP Gas (1) Quality cuts with MAPP gas require a proper … Read more

Air Carbon Arc Cutting And Welding

Air carbon arc cutting is an arc cutting process in which metals to be cut are melted by the heat of a carbon arc and the molten metal is removed by a blast of air. The process is widely used for back gouging, preparing joints, and removing defective metal. A high-velocity air jet traveling parallel to … Read more

Plasma Arc Cutting (PAC)

The plasma arc cutting process cuts metal by melting a section of metal with a constricted arc. A high-velocity jet flow of hot ionized gas melts the metal and then removes the molten material to form a kerf. The basic arrangement for a plasma arc cutting torch, similar to the plasma arc welding torch, is shown in figure … Read more
