During the welding process by the gas welding or arc welding, the gas flame or electric arc can be moved towards the direction of weld progression or opposite to the direction of the weld progression. Depending upon the direction of the move of flame or arc with respect to the ... Read More

There are various methods to control the temperature of the resistance heating at certain selected points in a furnace or oven, as per certain limits. The temperature control of resistance heating may be required in order to hold the furnace temperature constant or to vary it as per the requirements ... Read More

The device which receives electrical energy as input and converts it into the heat energy is known as a heating element.The wire employed for the heating element may be circular or rectangular. By determining the electrical input and its voltage, the size (or diameter) and length of the wire required ... Read More

Coreless Induction FurnaceCoreless induction furnace, also known as high frequency induction furnace, is a refractory lined vessel surrounded by an electrically energized, current carrying, water-cooled copper coil. As its name implies, no core is provided in the coreless induction furnace.The electric current in the copper coil forms an electromagnetic field, ... Read More

Shielded Metal Arc WeldingThe shielded metal arc welding (SMAW) is a type of electric arc welding in which coalescences of metals is produced by heat from an electric arc created between the tip of a consumable electrode and the surface of the base material at point of welding.The shielded metal ...

Materials Used for Heating ElementAn electric heating element is a device which converts electrical energy input into heat energy output. No single element, metallic or non-metallic, is used for designing the heating elements. Different alloys have been tried to obtain different temperature. The various heating alloys are given as follows ... Read More

Induction Heating FurnaceAn electrical furnace in which the heat is produced by induction heating of metal, is called the induction heating furnace. The induction heating furnaces have the capacities range from less than 1 kg to 100 tons and are used to melt various metals like iron, copper, aluminium, etc.Indirect ... Read More

Indirect Arc FurnaceAn electric arc furnace in which the heat is produced by striking the arc between two electrodes and then transferred to the charge to be heated is called an indirect arc furnace.In an indirect electric arc furnace, the electric arc does not come in contact with the charge ...
