ADVANCED TECHNOLOGIES R&D INDUSTRY

The electron beam welding process is used for the most critical of joining tasks in R&D projects today- to develop the technologies of tomorrow.

The ability and flexibility of the process to precisely tailor welds is unique, allowing the researcher to optimize the design of any scientific component.  PTR’s engineering staff has worked to develop weld processes used in many research and development fields and is available to contribute ideas based on decade’s long experience with this process.

Electron Beam Welding of Niobium Cavities

Niobium Cavity Welding

Around the world, niobium cavities are used in particle accelerators for advanced research. The stringent weld requirements for these cavities are a natural fit for the electron beam welding process. EB’s characteristic of welding under vacuum suits Niobium’s (very reactive) ’affinity for oxygen’ maintaining the highest purity levels.  The excellent process control which is characteristic of electron beam welding provides the required, smooth surface finish of the over/under weld beads- consistently and repeatedly.
