In aviation program we manufacture turning work pieces and welded parts for gliders, for our partner DG Flugzeugbau from Germany, in line with Organizational manual of quality assurance in the metal parts for gliders production.
Turning work pieces are made from tempered steel on CNC lathe. Welded pieces are manufactured from precise seamless steel pipes, thickness from 0,5 to 3 mm thick sheet to 1-6 mm. We use two different types of quality pipes, E235 + C (ST35 BK) and WNr.1.7734.4. The quality of sheet metal is WNr.1.7734.4. We are welding with modern TIG equipment.
