Electron beam welding is based on the premise that it is conducted in a vacuum. 【What is an electron beam?】 The heat electrons generated from a filament heated in a vacuum are accelerated by applying voltage between the cathode and anode, forming a flow of electrons that becomes a beam. 【What is electron beam welding?】 When this beam is deflected and focused onto the welding area using coils or lenses, the kinetic energy is converted into thermal energy at high speed, and this heat melts the material, resulting in welding. 【Features】 - Joining of difficult-to-weld materials: It is possible to join high-reflectivity materials like copper, high-melting-point materials like tungsten, and also dissimilar metals. - Low thermal impact: The penetration is deep with minimal thermal distortion, eliminating the need for distortion correction after welding. - High quality: Due to processing in a vacuum, it prevents gas entrapment and surface oxidation, resulting in fewer defects such as blowholes. Electron beam processing has a high energy density and can instantaneously provide a large amount of heat to the material, making it suitable for welding applications on difficult-to-process materials in fields such as nuclear and aerospace. Additionally, its good energy stability and minimal distortion due to thermal effects have led to its widespread use in the automotive industry. Please feel free to contact us.
