Electrolysis Process of chemical change taking place in a electrolyte by the passage of electricity is called Electrolysis It is a process of decomposition of an electrolyte substance, which is present in liquid state,...
Butt Welding are two types, Upset butt welding & Flash butt welding Upset butt welding : Two work pieces to be welded together are fixed in clamps and butted against each other. Electrodes used...
Seam weld, is a type of Resistance Welding. It is a series of continuous spot welds. .In this welding tipped electrodes are replaced by roller electrodes leads the contact area of electrode should be...
Spot welding is a type of Resistance Welding.It is usually employed for joining sheet metal structure.It Only provides mechanical strength and is not air or water tight. The workplace or plates to be welded...
Electrical Welding, means the joining of two metals placed together by heating them to melting point by the use of electrical energy. Advantages of Welding: A welded joint is as strong as the base...
The core less induction furnace operates on the same principle of an electric transformer. The eddy currents developed in any magnetic circuit are given by the equation eddy currents α B2 f2 (B =...
Indirect core type induction furnace is based on the principle of Faraday’s law of mutual induction. There is a primary winding through which an AC current is passed. The secondary winding forms the walls...
