Electron beam welding - welding power source in which is the kinetic energy of electrons in the electron beam formed by the electron gun.
The mechanism (Greek μηχανήmechané -. Machine) - the internal structure of the machine, appliance, apparatus, leading them into action . The mechanisms used to transmit motion and power conversion (gear pump, an electric motor).
Welding current - one of the main parameters that characterize the electrical properties of the arc. Together with svaronym voltage, welding current at steady welding mode expresses a static current-voltage characteristic.
Welding tub - part weld in the product, where the base metal has reached the melting point of the filler material and which penetrates. The presence of the weld pool is the key to a successful welding process.
Welding of steel - welding of steel products and its alloys.
