  • Hello friends todays video is very important to understand the new type of welding machine
    that is called as electron beam welding machine.
    Electron beam (EB) welding is a fusion welding process whereby electrons are generated by an electron gun and accelerated to high speeds using electrical fields. This high speed stream of electrons is tightly focused using magnetic fields and applied to the materials to be joined. The beam of electrons creates kinetic heat as it impacts with the workpieces, causing them to melt and bond together.
    Electron beam welding is performed in a vacuum environment as the presence of gas can cause the beam to scatter. Due it being a vacuum process and because of the high voltages used, this welding method is heavily automated and computer controlled. As a result, specialised fixtures and CNC tables are used to move the workpieces inside the welding vacuum chamber.
    What are the Advantages of Electron Beam Welding?
    1. The electron beam welding process is a very precise technique and is also highly repeatable due to the automation
    2.This welding technology also creates strong and pure joins that can be used across a number of high-end applications for a wide range of industries
    3.Electron beam welding also shows high strength properties, maintaining up to 95% of the strength of the base materials
    4.As the technique is performed in a vacuum environment there are no impurities left by the process
