This set of articles contains information about cutting of metals using different kinds of arc welding processes.
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 When steel is exposed to high temperatures of the order of 1600°F (871°C), it gets oxidized very fast by the oxygen. Steel gets oxidized by oxygen at room temperatures too, but … Read more
Plasma arc cutting works on the same basic principles as the plasma arc welding. A column of hot ionized plasma issues from a constricting nozzle at a high velocity, and melts the base metal. It then removes molten metal to produce a kerf. In this article, we shall see in brief about the various components … Read more
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 The right combination of parameters such as preheating flame, oxygen pressure, … Read more
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
