Quality

„Quality means – doing things correctly even when nobody is looking” Our main goal is to provide quality products for our customers, to be a reliable company to our suppliers and to create a good working environment and conditions for our employees. Our mission is reflected in the company's Quality Policy. We commit to fulfil and maintain our quality management system according to the internationally accepted standards. A major part of the quality system is the continuous improvement of the company's policies and processes.

The Quality management system is established and certified according to the EN ISO 9001:2008 since 2005, the company also has been certified according to the SOŠ AQAP 2120:2010 (military products), STN ISO 3834-2 (Quality system of welding), DIN 18800, DIN 15 018, DIN 4132, EN 1090-2+A1 (steel construction welding system), DIN EN 15085-2 (welding of railway vehicles and their parts) and has an accredited calibration laboratory in the company to meet the requirements of the standard ISO/IEC 17025:2005.

The quality of our products is our priority and therefore the quality control is carried out in three phases: Entry control, in-process control and output control. The weld quality control is ensured by qualified workers. These employees are holders of non-destructive weld testing certificates (NDT testing – ultrasonic testing, magnetic–powder testing, penetration testing and visual tests of welds). The 3D coordinate measuring machines MORA 0150 and LEICA TRACKER are used for dimensional control. Certified welding supervision is a part of the quality system which trains, supervises and directs workers who perform the welding processes.

The quality improvements are ensured by collaboration with the Industrial Institute of Slovak Republic, Prvá zváračská a.s. (a joint stock company), Technical University in Zvolen, Consulting & Control of Welding Ltd. and others.

Calibration and Testing Laboratory PPS Group a.s. (a joint stock company) has its own accredited calibration and testing laboratory. The laboratory is used to carry out calibrations of length gauges, plane angle gauges, thermometers, pressure gauges and measurement of divergences from linearity and planeness according to the ISO/IEC 17025:2005 standard. It is capable of measuring the straightness of the rulers, the planeness of the control plates and measuring the geometric variables and divergences of the shape on the 3D coordinate measuring equipment within the ISO/IEC 17025:2005 standard. The calibration laboratory is used not only for our own purposes but is also outsourced to other companies. Our people constantly thrive to offer the highest standards through continuous research in the subject area. Our experts regularly attend seminars and training sessions. They update their knowledge and keep up with the developments in the research methods by sharing their experience with other professionals.

Metalographical Laboratory and Mechanical Testing PPS Group Metallographic Laboratory performs activities to increase the quality of our products. We provide complete control of the supplied materials via mechanic and metallographic tests. Besides this, it carries out metallographic analysis of the weld joints, tension and bending tests at the environment temperatures, shock test in bend at the environment temperature as well as at lower temperature and hardness measurements HBW, HV, HRC, HRB and micro-hardness.
Metallography is used in connection with: - Material verifications
- Welding procedures
- Damage assessment
- Heat treatment

The Quality Lab carries out a number of mechanical tests and has a special engineering workshop for taking samples. We test in accordance with most standard test methods, and also provide tests according to the customer's own specifications and wishes.

Our material testing capacity includes: - Tensile testing
- Bend testing
- Impact testing
- Compression testing
- Brinell hardness testing
- Vickers hardness testing
- Rockwell hardness testing (with a steel sphere)
- Rockwell hardness testing (with a diamond cone)
- Micro-hardness examination

Damage analysis: The industry is constantly experiencing that equipment does not meet expectations. We use a combination of analyses, visual inspection, physical tests and experience to identify the cause. A metallurgist thoroughly evaluates all aspects of the damage and gives a conclusion and a recommended solution.
