FOCUS GmbH offers a range of electron beam welding machines for various applications, including sensor housing and vacuum encapsulation. Our precise electron beam welding machines are designed to provide high accuracy and repeatability, making them suitable for manufacturing small and complex parts with tight tolerances.

Using a FOCUS electron beam welding machines for sensor housing and vacuum encapsulation with unique precise electron beam gun allows provides following benefits:

  • High Precision: FOCUS electron beam welding machines are capable of achieving high welding precision due to their advanced beam control systems. The beam can be precisely focused and directed to the welding area, ensuring a consistent and repeatable welding process. This is important for manufacturing sensors, where small variations in welding can have a significant impact on the final product’s performance.
  • Vacuum welding allows to provide vacuum-tight seams and does not require further pumping of the sensor. Electron beam welding machines are also capable of creating a hermetic seal, ensuring a vacuum-tight joints for sensor housing and vacuum encapsulation applications. This is achieved by maintaining a low-pressure environment inside the welding chamber during the welding process, which prevents any gas or moisture from entering the enclosure. Operation pressure starts from 3*10-4 mbar (for W cathode) and 5*10-6 mbar (for LaB6 cathode).
  • Automated Welding: FOCUS electron beam welding machines are equipped with CNC control. Machines can be programmed to weld multiple parts at once, with precise control over the welding parameters to ensure consistent quality and high productivity.
  • Material Compatibility: Electron beam welding technology allows to weld a wide range of similar and dissimilar materials including copper, aluminium, titanium, stainless steel, tantalum, zirconium, niobium and others. This makes it suitable for manufacturing sensors which require specific material properties, such as corrosion resistance or thermal conductivity.

FOCUS GmbH’s electron beam welding machines provide advanced features and capabilities for manufacturing precise sensor housing and vacuum encapsulation. Their high precision, hermetic sealing, automated welding, and material compatibility make them an ideal choice for manufacturing these critical components.
