RT radiographic control is a volumetric examination that allows images of the contents of a solid to be obtained by imprinting a sensitive element (film, screen, etc.) by ionizing radiation such as X-rays or γ rays.

This investigation technique is used in the control of welds, castings, molded products, forgings, plastic materials, composites, civil construction components, etc.

At our headquarters we can handle products weighing up to 10 tons and we are also able to offer the pick-up and return service of the part subject to control, with minimization of lead time.

Ultrasonic inspection is a non-destructive method in which high-frequency sound waves are introduced into the material to be examined, with the aim of:

• Highlight superficial or internal defects
• Measure the thickness of the materials
• Measure the distance and size of the discontinuities

Magnetoscopy is a type of non-destructive testing used to search for surface and subsurface indications in metal pieces. It is based on the attraction of ferromagnetic particles dispersed in liquid which highlight the discontinuities found in a direction generally transverse to the magnetic field, determining a deviation of the flux lines of the magnetic field itself.

Non-destructive testing using penetrating liquids is a type of testing that allows you to check the integrity of a sample and detect the presence of surface defects thanks to the application of a particular type of liquid that manages to penetrate inside the discontinuities.

Testing using penetrating liquids exploits the capillarity method, i.e. the ability of a liquid to rise inside a capillary tube, and the physical characteristics of liquids such as viscosity and surface tension. The penetrating ability is a very important requirement that defines the sensitivity of the exam.

The examination can be carried out using two types of methods: the color contrast method and the fluorescent liquid method

Inspection with penetrating liquids is a particularly suitable method for highlighting and locating surface discontinuities, such as cracks, porosity, and folds, quickly and economically and with great accuracy.

Most common and basic inspection method. Visual examination means the inspection of objects with the naked eye or with the sole aid of lenses or endoscopes with a low magnification factor.

The correct and in-depth visual examination of objects and the morphological characteristics of their surfaces is of fundamental importance in the diagnosis of metallurgical defects.

The visual examination is essential as the first non-destructive control of both the raw materials intended for production and the finished or semi-finished products. When it is not possible to directly access the object or surface to be examined, more or less sophisticated equipment such as borescopes, endoscopes and cameras are used.
