Oxy-fuel cutting and oxy-fuel welding can be described as the processes of using oxygen and fuel gases to either cut or weld metals. There are some striking differences between these two processes. In the first process, a cutting torch is made use of for heating ferrous metal to a temperature of around 980 degree Celsius. An oxygen stream is being trained on a hot metal that combines with iron chemically which later flows from the kerfs, or cut in the form of slag of iron oxide. In the second process, a

Casting is a process in which liquid material made from heating metals, is poured in a module, to give the liquid a desired shape. Then the liquid is cooled and a solid object in the desired shape and size is obtained. Casting Jewelry is the latest
