The company was founded in 1904 by Swedish businessman Oscar Kjellberg in Gothenburg, Sweden. The company sells equipment used in welding and cutting . Other notable CEO was Lars Westerberg who ran ESAB for three years. The ESAB was acquired by Charter International in 1994. The ESAB group was acquired by Colfax Corporation on 13 January 2012.
Plasma cutting. Plasma cutting is a process that cuts through electrically conductive materials by means of an accelerated jet of hot plasma. Typical materials cut with a plasma torch include steel, stainless steel, aluminum, brass and copper, although other conductive metals may be cut as well. Plasma cutting is often used in fabrication shops ...
Plasma torch. A plasma torch cutter. A plasma torch (also known as a plasma arc, plasma gun, plasma cutter, or plasmatron) is a device for generating a directed flow of plasma. [ 1][ 2][ 3] The plasma jet can be used for applications including plasma cutting, plasma arc welding, plasma spraying, and plasma gasification for waste disposal. [ 4]
A plasma etcher, or etching tool, is a tool used in the production of semiconductor devices. A plasma etcher produces a plasma from a process gas, typically oxygen or a fluorine -bearing gas, using a high frequency electric field, typically 13.56 MHz. A silicon wafer is placed in the plasma etcher, and the air is evacuated from the process ...
Plasma cleaning is the removal of impurities and contaminants from surfaces through the use of an energetic plasma or dielectric barrier discharge (DBD) plasma created from gaseous species. Gases such as argon and oxygen, as well as mixtures such as air and hydrogen/nitrogen are used. The plasma is created by using high frequency voltages ...
Inductively coupled plasma. An inductively coupled plasma ( ICP) or transformer coupled plasma ( TCP) [ 1] is a type of plasma source in which the energy is supplied by electric currents which are produced by electromagnetic induction, that is, by time-varying magnetic fields. [ 2]
A plasma propulsion engine is a type of electric propulsion that generates thrust from a quasi-neutral plasma. This is in contrast with ion thruster engines, which generate thrust through extracting an ion current from the plasma source, which is then accelerated to high velocities using grids/ anodes. These exist in many forms (see electric ...
In a large, high-sided skillet over medium heat, melt butter. Add onion and 1/2 teaspoon salt and cook, stirring occasionally, until softened, about 7 minutes. Add tomato paste and cook, stirring ...
