Note: EBW operates in vacuum (10^-4 to 10^-1 mbar). Penetration depth depends on voltage, current, speed, and material thermal properties.

Reference

Electron Beam Welding: Beam Power: P = V(kV) x I(mA) / 1000 kW Penetration: d = k * P / sqrt(v) (empirical, k varies by material) Heat Input: H = P * 1000 * eta / v (J/mm) Aspect ratio typically 10:1 to 30:1
