Internal welding applications 

• Niobium cavities
• Copper cavities
• Aluminium casing

Advantages

• Extremely smooth weld seam on the inside surface of the cavity without needing any extra machining
• Welding of unreachable seam
• Complete inside welding with/without smoothing
• Inside smoothing pass for outside welded parts
• Different diameters are possible for welding of iris and equator from the inside (up to 1.3GHz cavity included).
