Incoming inspection

All incoming materials, parts, and components undergo full incoming inspection for compliance with:

  • Engineering documentation
  • Chemical composition
  • Mechanical properties

Linear and operational control

In the manufacturing process, all parts undergo quality control for compliance with the engineering documentation and technical specifications. Daily checks of process discipline have allowed to achieve consistently high machining quality and minimize the reject rate.


The company operates an accredited NDT lab employing ultrasonic, capillary, acoustic emission, magnetic particle testing, gamma-ray examination, and other test methods.


Product testing

Gusar has 22 test stations.

100% of Gusar's output is tested for strength, density, and tightness

according to GOST 5762.

All products meet tightness class A in accordance with GOST 9544-93.

Upon request, the company's QC lab can conduct additional tests, e.g. QCT, £-phase, ultrasonic, acoustic emission tests, MPI, X-ray, and other examinations.
