Electric welding is a process of joining two metal pieces using heat generated from an electric arc. The arc melts the base metal and filler material (electrode), which fuses together to form a strong joint upon cooling.
An Electric Arc Furnace (EAF) is a type of furnace that uses electric arcs to generate heat for melting and refining materials, primarily metals like steel and alloys. It operates by creating an arc between electrodes, which generates extremely high temperatures to melt the charge (raw material).
A Travelling Wave Tube (TWT) is a specialized vacuum tube that amplifies microwave signals by interacting with an electron beam traveling through a helical slow-wave structure. It is widely used in radar, satellite communication, and electronic warfare due to its high power and broadband amplification capabilities.
A Reflex Klystron is a type of vacuum tube used to generate and amplify microwave signals. It operates on the principle of velocity modulation of an electron beam. Reflex Klystrons are widely used in radar systems, microwave communication, and signal generation due to their simplicity, compactness, and efficiency in producing high-frequency oscillations.

Laser Beam Welding (LBW) is an advanced welding technique that utilizes a highly focused laser beam as the heat source to join materials. This method is widely recognized for its precision, high welding speed, and ability to join hard-to-reach or delicate areas. LBW is extensively used in industries such as automotive, aerospace, electronics, and medical
An Electrical Drive is an electromechanical device that uses electrical energy to produce mechanical motion. It consists of a motor, a control system, and other components that work together to regulate and control the speed, torque, and position of the motor. Electrical drives are used in various applications ranging from household appliances to industrial machinery.
An optical pyrometer is an instrument used to measure high temperatures, often in industrial applications, by comparing the intensity of radiation emitted by a hot object to that of a calibrated light source. Unlike contact thermometers, it measures temperature without making physical contact with the object, making it suitable for measuring extreme heat such as
Dielectric heating, also known as capacitive heating or radiofrequency (RF) heating, is a process in which non-conductive (dielectric) materials are heated by applying an alternating electric field. This heating occurs due to the molecular polarization of the dielectric material when subjected to a high-frequency AC electric field. It is widely used in industries such as
A function generator is an electronic device used to generate electrical waveforms over a wide range of frequencies. It is widely used in the fields of electronics, communications, and testing to create specific signals for testing, calibration, and experimentation. Figure 1: Block diagram of a function generator.
