Precision electron beam welding equipment
Product Description:
The core component of our electron beam welding machine is MICROBEAM: a unique 2 kW electron generator with precise electron beam control capability. High precision control of the size, position, and power of the electron beam spot can optimize to achieve a very narrow process window, and the electron beam spot can be adjusted between 25 µ m or more than 1 mm.
The three pole structure electron gun can achieve particularly precise control of the electron beam. Using directly heated tungsten cathodes (needles or ribbon filaments) or LaB6 cathodes to form electron beams with axial symmetry and minimal cross effects.
The high-voltage power supply provides a continuously adjustable voltage of 5 to 60kV (with a minimum step size of 20V), and the electron beam current ranges from 15 µ A to 33 mA (with a minimum step size of 10 µ A). Combined with pulse working mode, it can solve the most demanding process window problems.
The standard precision electron beam welding machine provided by FOCUS can be used for various welding tasks. All machines are equipped with MICROBEAM generators. Our MICROBEAM generator can also be purchased separately as a component to upgrade your existing electron beam welding machine.
