  • EB welding of large parts used in aerospace, power generation and many other industrial applications require chambers with enough capacity to accomodate the work envelope and the range of motion needed. PTR is a leading manufacturer of these EB welders and can provide the most suitable system for any application.

    PTR's EB chamber welders are modular systems built with proven designs using high quality off-the-shelf components. Standard chamber sizes range from 1.5 cubic feet to more than 2,000 cubic feet (60 m3). Our High Voltage (150 kV) and Low Voltage (60 kV) Beam Generators consistently and reliably produce a high quality beam.  The external electron beam generators on these systems is outside of the harsh welding environment which protects these components and simplifies routine maintenance.
