Shimadzu X-ray technology is a major part of Japan's fluoroscopic technology history

Dr. Roentgen discovered X-rays - Shimadzu succeeded in taking radiographs

Shimadzu Corporation made history in 1909 by developing Japan's first
commercial application of a medical X-ray apparatus. In fact, one could
say X-ray equipment is one of Shimadzu's core technologies. Shimadzu
has consistently acted as a pioneer in the development of X-ray
technology both in Japan and overseas, leveraging its accumulated X-ray
expertise to become one of Japan’s top manufacturers in not only the
medical field, but in a variety of industrial fields as well.


First industrial x-ray apparatus "WELTES"

NDT began in Shimadzu as a part of the “medical division”. The industrial X-ray apparatus “WELTES” was developed by applying X-ray technology cultivated in the medical equipment field, and was first released commercially in 1933. At that time, with improvements in welding technology, a need arose for non-destructive testing of steel pipe welds in factories. Customers were waiting for the release of an industrial X-ray device strong enough to penetrate steel plates. .Thus, “WELTES” was released. Subsequently, an X-ray fluoroscopic system with an image amplifier was released in 1962, and a system for electronic devices was released in 1984. Shimadzu then succeeded in developing Japan’s first microfocus X-ray CT system in 1999, and has since come to be regarded as Japan's top NDT manufacturer. 


X-ray systems

These days, even though NDT is focused on the standard microscopic inspection, we have also had a number of large-scale, custom order units. In addition to conventional welded steel pipe inspection units, custom-orders included aluminum wheel inspection units, inspection units for large-scale tires of 4 ton, and inspection units at shipyards. With the development of Japan's H1 rocket came a demand for inspections of rocket fuel tanks. In response to this, Shimadzu developed the “Betatron”, an instrument with a maximum output of 25 MeV. After it was delivered and used for testing, during subsequent launches from Tanegashima Island a close watch was kept on the rocket as a kind of prayer for a good outcome. launches were incident-free, thanks to those X-ray inspections.
