The technology at the heart of PTR’s EB welding systems was originally developed in the 1950’s by Dr. h.c. Karl-Heinz Steigerwald while working for Zeiss in Germany. United Aircraft (now United Technologies Corporation) purchased this technology and began producing electron beam welders in their Hamilton Standard facility in Windsor Locks, CT USA. Hamilton Standard took the German design and worked to make it a robust, user friendly system. These electron beam welding systems were quickly adopted by the industry and many of these vintage Hamilton Standard machines manufactured in the 1960’s/70’s are still in use today. The Hamilton Standard EB welder business was sold to Leybold-Heraeus Vacuum Systems in 1976 and the US facility was moved to its current location in Enfield, CT. Leybold then sold the business in 1989 and the business became PTR-Precision Technologies. In 2004 the PTR and Steigerwald EB welding businesses were combined to form Global Beam Technologies Group (GBT). The combined resources of the new group allowed a renaissance of technical development that has led to the advanced features and systems designs available from PTR today.
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.
PTR’s main U.S. facility in Enfield, CT designs, manufactures, refurbishes and retrofits electron beam welding systems and provides contract welding services.
