Advantages

Advantages of the electron beam welding in comparison with other welding processes are:

  • thin and deep weld seams with low width
  • very low heat input on high power density
  • minimal shrinking and contraction
  • low residual stress by small heat influence zone
  • low weld processing times on high weld speeds
  • simple and economic seam preparation (butt weld as a standard)
  • welding of two and three-dimensional seam geometries, on heavily accessible places too
  • good repeatability by real time automatic control of electrical process parameters

Compare GMAW joint and EB joint, joint penetration = 30 mm



Transverse shrinkage and angle shrinkage of different welding
processes, joint penetration = 10 mm in steel
