Since its founding in 1968, PROTO Manufacturing has been involved in the development and application of non-destructive evaluation technology. In the early eighties, PROTO recognized that many of the problems had undesirable residual stress as their root cause. PROTO selected x-ray diffraction (XRD) technology because of its promise for providing quantitative measures of residual stress (RS) both safely and non-destructively. PROTO set a goal to develop XRD technology sufficiently to allow practical problem solving in laboratory, factory and field environments. A continuous and considerable development effort over the years, has succeeded in advancing the state-of-the-art to achieve this goal, and PROTO has expanded its XRD product line to include powder diffraction, Laue orientation systems, x-ray tubes and custom XRD equipment. PROTO has become a leading provider of portable and laboratory based x-ray diffraction systems.
PROTO Manufacturing also provides measurement services through its ISO 17025 laboratories in the United States, Canada and Japan.
