About PTR

Who is PTR Precision Technologies?

PTR Precision Technologies, Inc., a leading US manufacturer of EB welding equipment, located in Enfield, CT (USA), was incorporated in 1989 as a full-service high-energy beam processing company. At that time PTR and its sister division in Germany acquired the worldwide EBW activities of Leybold AG.

Due to its predecessors, Hamilton (HSD) and Leybold (L-HVS), PTR's roots extend to the initial development and application of EB processing technology (back in the 1950's). Our wealth of experience accumulated from manufacturing and delivering a broad variety of electron beam equipment to all industries and the daily use of our welders in our job shop, serves as the basis for the modern day EB equipment we presently produce.

Why PTR Precision Technologies? 

With combined sales of well over 2000 electron beam welders and hole drillers, PTR and its sister divisions are by far the largest supplier of electron beam welding (EBW) and drilling equipment in the world. A long history of continuous leadership in the field of high-energy beam (HEB) technology has permitted PTR to participate in the accomplishment of a number of "firsts" in this field:

•  first precision high vacuum EBW unit.
•  first production partial vacuum EBW unit.
•  first production nonvacuum EBW unit. 
•  first E-Braze process.
•  first EB deep welding of -TiAl (Gamma Titanium Aluminide).
•  first HEB welding of engineered/tailored blanks.

The ability to integrate the latest technologies in a continuous effort to increase product reliability, coupled with an extensive knowledge of the process, has earned PTR the high reputation it holds within the industry today.
