The camsizer uses the principle of digital image processing. Although working in the conventional
field of dry screening analysis, the camsizer has many valuable extra functions such as grain shape,
specific surface, convexity, etc. The camsizer range is between 30 µm and 30 mm. Internal electronic
processing uses up to 10,000 size classes. The analytical result can be saved in up to 1,000 size classes.
The size classes which are displayed can be defined by the user.
The optical emission spectrograph of the firm ARL is used for the chemical analysis of metal samples.
It permits the simultaneous analysis of 20 elements with little time for sample preparation. All data is saved
in the company-wide Oracle database and is available online directly.
The X ray provides valuable information on the integrity of a Thermit weld by non-destructive method. Integrity
means the absence of defects in the weld. This method is suitable, in particular, for detecting volume defects,
such as pores or shrinkage or inclusions of sand or slag.
X-ray tests are a quick method of detecting flaws in welds both during development and quality control and
also during defect analysis. An advantage of ultrasonic testing is that the shape of a defect and also its
exact location in space and its extension can be defined.
The X-ray principle is the same as that known from medical examinations except that the examination of rails
requires a much higher intensity of the X rays than in medicine. To penetrate the fairly thick profile of a rail
and expose a film placed behind the rail, up to 5 minutes are needed despite the high radiation intensity.
The X-ray system operates with high tension of 300,000 Volt and, for safety reasons, must be set up in a lead-clad
room that is subject to a special safety acceptance test.
Ultrasonic examination is a non-destructive method for testing Thermit welds of rails. Many railways use ultrasonic
testing as routine method for rails. To comply with requirements of the railway companies concerning the ultrasonic
specification already at the development stage of new welding methods, Elektro-Thermit employs a team of experienced
welders who know the ropes of ultrasonic examination.
The FTIR-Spectrometer is used within the infrared spectroscopy. Especially for time-dependent actions, considerably quicker measurements can be proceeded. Thus allows to achieve better and faster knowledges of the used chemicals starting from the goods receipt of the commodities until the inspection of th end-product.
