Our company has a full machine-building cycle for the production of chemical equipment:


Welding production of NPO Passat is certified according to DIN EN ISO 3834-2 and EN 1090-2 standards. Welding technologies are certified in accordance with the requirements of STB ISO 15614-1, STB ISO 15614-5, as well as DIN EN ISO 15614-1:2017+A1:2019. Welding works are coordinated by a specialist qualified as an International Welding Engineer.
TIG welding of carbon and high-alloy steels,
mechanized shielded gas welding of carbon and high-alloy steels (MIG/MAG),
manual arc welding with covered electrodes of carbon and high-alloy steels (MMA),
welding of alloy/Monel 400 alloys (TIG) with a non-consumable electrode in shielding gases,

automatic submerged-arc welding of carbon and high-alloyed alloys.
CULTURE OF PRODUCTION
The quality management system at Passat Research and Production Association is certified for compliance with STB ISO 9001-2015.
We have a full incoming quality control. It includes control of supplied metal, welding materials and components.
To prepare parts for welding we use abrasive materials of 3M, Pferd brands, to degrease parts - special means of 3M, Loctite and their analogues;
We use Lincoln Electric welding equipment (AristoMIG 4004i Pulse models); ESAB (AristoMIG 4004i Pulse models), as well as ESAB and Böhler welding consumables.
We carry out preparation, assembly, visual and capillary inspection of welds.
