Production machines

During the manufacturing process, the dimensional verification is performed (width, length, weld, curve and 5 links)
After manufacturing, the links are inspected on the following items: Visual (verification of imperfections, which can be corrected with grinding without losing the specified diameter), Magnetic particle (if there are surface cracks) and Ultrasound (if there are internal discontinuities).

3 production machines ranging from 70 to 120 mm R3 - R4S:
  • I5, 70 - 120 mm.
  • I8, 70 - 120 mm.
  • I9, 86 - 120 mm
Four arms carrousel continuous production system.
Induction heating.
Welding control CITR system.
Using Qweld for parameter control, in progress actions to turn it 100% operative in the 3 machines.
M5, M8 and M9 equipped with inspection towers for conventional UT and MT.
