Technology
- Soldering process of metal-glass structures (for example, solder the metal-glass leads in the devices case).
- Laser and resistance welding are performed to seal the cases of various configurations (for example, s/c device in a cylindrical or rectangular case with leads).
- Manufacturing of rectangular pipes of various sizes and rectangular elements of cases (frames, covers, bases), their connection at assembling cases.
- Manufacturing, welding, annealing of permalloy magnetic screens of 79NM, 81NM types and etc. Dimensions are 3000*300*400 mm.
