General principles of testing of metals

When monitoring articles on the curved surface of a radius of 100 to 150 mm oblique prism crawler treated so that its radius of curvature of the contact surface was somewhat larger than the radius of curvature of the surface of the article. When monitoring of such products used defectoscope (Descrydefect) finders with a rectangular piezoceramic plates oriented along the surface of the product. Under the control of the immersion method is used to focus the ultrasound.

Descrydefect SD 340b is equipped with the latest spectrometer for precise analysis, rapid identification and sorting of samples. The plant is programmed most famous steels and the resulting spectrum of the computer will offer a list of steels with the same chemical composition. More here: http://i-engineering.hk/d340b.php
