Welding
cialists working in PINK’s welding departments process with great precision high-grade materials like stainless steel, steel, aluminium and special metals such as Invar, titanium, Zircaloy, molybdenum, tungsten, tantalum, rhenium, niobium etc. Far from being out of the ordinary, vacuum-tight welds within the UHV and XHV ranges are part and parcel of everyday production.
Modern electron-beam welding units
Electron-beam welding (EBW) is the only reliable joining method that meets the high quality requirements of many special applications. With its contactless mode of operation and high working speed, electron-beam welding under vacuum (without gases and additives) has numerous advantages in terms of quality and economy. In combination with electronically controlled work parameters, the constant beam diameter at the focus ensures excellent reproducibility and a high rate of progress.
