Non-destructive testing

The non-destructive testing service includes the following elements:

  • Visual testing (VT)
  • Penetrant testing (PT)
  • Magnetic testing (MT)
  • Ultrasonic testing (UT)
  • Phased array ultrasonic testing (PAUT)
  • Radiographic testing (RT)
  • Leak testing
  • measuring wall thickness
  • dielectric insulation control
  • measuring paint coat thickness

Accreditation Certificate

The laboratory for non-destructive testing has been accredited since 2018 according to the standard HRN EN ISO / IEC 17025: 2007. Methods for non-destructive testing of welded joints (RT, MT, UT and PT) have been accredited.

Other business


Welder certification is done following the latest European standards and their requirements for the following welding processes: MIG, MAG, REL, TIG, gas welding


Welder training is done according to our own program in our welding school in Sesvete using the following methods: REL, MAG, MIG, TIG, gas welding

Creating technical documentation for welding

WPS list, welding procedure qualification record (WPQR), welding technology

Supervision and control

Supervision and control over the execution of welding works.

Mechanical calculation

In cooperation with our partners we offer: static calculation of construction, dynamic calculation of construction etc.


Radiographic testing

Radiography is a process of recording inner and outer defects in three-dimensional objects on a two-dimensional film plane.

Ultrasonic testing

Ultrasonic testing is based on the fact that solid materials are good at carrying sound waves.

PAUT- Phased array ultrasonic testing

An advanced method of ultrasonic testing that has applications in industrial nondestructive testing.

Magnetic testing

With the use of magnetic flux it is possible to find flaws on the surface of the object as well as directly below the surface.

Penetrant testing

Penetrant testing is one of the first widely accepted non-destructive testing method.

Visual inspection

Visual inspection is the oldest and the most common non-destructive testing method.
