Global Beam Technologies Group

In 2005 PTR USA and PTR Strahltechnik GmbH, Germany joined forces with Steigerwald Strahltechnik GmbH, Germany. These three electron beam technology companies comprise the Global Beam Technologies Group - your worldwide connection to expert welding solutions from contract welding to the manufacture of specialized EB systems.

PTR in Langenselbold, Germany has its origins in the electron beam welding division of the company Leybold-Heraeus, later Leybold AG.  PTR in Enfield was formerly the electron beam division of Hamilton Standard in Windsor Locks, CT. Steigerwald Strahltechnik was established by the founder of modern EB processing himself, Dr h.c. Karl-Heinz Steigerwald.

Companies from all over the world benefit from the expertise, reliable technology and decades of experience shared by our EB technology specialists.

We take care of YOUR connections – worldwide.
