The complete refining of oil consists of the following operations: • separation of solid impurities that is impurities not soluble in oil, • separation of free water, • partial separation of dissolved moisture that is dehydration or drying, • de-gumming, • separation of free fatty acids or neutralization,  • separation, reduction or destruction of pigments, that is bleaching, and • separation, reduction of destruction of volatile compounds affecting odour or taste that is deodorization.

The secondary voltage, open circuit voltage (OCV) is in the range of 50 – 100 V with the current ratings varying from 5 A – 800 A.

At first (1922), the aim of the process was to separate completely the mesocarp of the fruit in order to obtain clean nuts because at that time the separation of the cake produced by the dry process into fibre and nuts was not well established.

Welding received special impetus during World War II for the mass production of industrial items and war equipment. Today, there are more than hundred welding processes that enable engineers to join almost all commercial metals and alloys in many sizes and thickness ranging from a fraction of a millimetre to more than 500 mm. In the last few years, many of the high temperature alloys have been fabricated by welding together critical components like in the case of guided missiles, jet aircraft and nuclear power plants. These developments would not have been possible without the use of welding.
