The process

A high energy and extremely focused beam of electrons is used to join metals, with no filler metal required. This approach results in a small heat-affected zone with minimal distortion, while the bulk of the assembly remains cold and stable.

The welds produced are narrow and deep (up to 30 mm) and as it takes place in a vacuum we can achieve almost pore-free welds. Computer controls ensure minimal operator dependence and a high degree of reproducibility.

EBW lets us weld oxygen-greedy materials and materials with high thermal conductivity. Pronexos can weld a range of materials, including – but not limited to – reinforced steel, stainless steel, aluminium, copper, titanium, zirconium and niobium.
