NAIS Company offers NDT services including equipment and consumables. It also offers inspection services technologies such Magnetic Particle Testing, Positive Material Identification, Post Weld Heat Treatment, Dye Penetrant Testing, Ultrasonic Testing, Hardness Testing, Radiographic Testing and much more.

Magnetic Particle Testing

Magnetic testing (MT) is a nondestructive method widely used in the field of materials technology. This method allows highlighting discontinuities or cracks open out or close to the surface. This technique works only on ferromagnetic material.

Positive Material Identification (PMI)

Positive Material Identification (PMI) is the analysis of a metallic alloy to establish composition by reading the quantities by percentage of its constituent elements.

Post Weld Heat Treatment ( PWHT )

Post Weld Heat Treatment ( PWHT ) is defined as one of heat treatments done after welding/machining to improve the Chemical mechanical properties of weldment / machined surfaces.

Dye Penetrant Testing

Penetrant testing is used to reveal emerging surface defects such as cracks on the surface of all non-porous materials.

Ultrasonic Testing

Ultrasonic inspection is a nondestructive method for detecting defects within a material. This method is based on the transmission and reflection of ultrasonic wave type within a material

Hardness Testing (HT)

This method is used for the determination of the hardness of the material, parent metal and the weldment after heat treatment.

Radiographic Testing (RT)

The Industrial radiography is similar to the medical radiography. It consists in crossing the piece to be inspected by a beam of X-rays (or gamma), and irradiating a film placed behind the piece.

Vacuum Box Testing

This method is a non-destructive examination used when trying to locate weld seam leaks.
