High power density

  The commonly used acceleration voltage range for electron beam welding is 30 to 150 kV, the electron beam current is 20 to 1000 mA, the electron beam focal diameter is about 0.1 to 1 mm, and the electron beam power density can reach 106 W/cm ² above.

 

Accurate and fast controllability

As a fundamental particle of matter, electrons have a very small mass and a certain negative charge, with a charge to mass ratio of up to 1.76 × 1011C/kg, through electric and magnetic fields, the electron beam can be quickly and accurately controlled. This characteristic of the electron beam is significantly superior to that of the laser beam, which can only be controlled using a transparent and reflective mirror and is slow in speed.
