Electron beam welding
Pronexos has 50 years of experience in electron beam welding (EBW) — a welding process that produces coalescence with a concentrated beam composed primarily of high-velocity electrons, impinging on the joint. The process is used without shielding gas and without the application of pressure.
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 enables the welding of oxygen-greedy materials and materials with high thermal conductivity. Pronexos can weld a range of materials, including reinforced steel, stainless steel, aluminium, copper, titanium, zirconium and niobium.
