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
