WELDING
Surfaces are flattened and refined through milling. Welding is performed by our operators, or by our external certified partners in case thermal treatment is needed.
POLISHING
The CNC-worked surfaces are polished, thus guaranteeing maximum quality level.
NDT - NON DESTRUCTIVE TESTING
NDT is a testing and analysis procedure that allows for a cost-effective way of checking a product’s internal structure, integrity, welding defects, surface cracks etc…
Many imperfections cannot be seen by the human eye, that is why a selection of machines are needed to run those tests. The main advantage of NDT comes from the fact that it does not permanently alter the article that’s undergoing inspection, in addition to not damaging it.
NON-DESTRUCTIVE TESTS:
- Magnetic Test (MT): a method used to detect surface and slightly subsurface flaws in ferromagnetic materials.
- Liquid Penetrant Test (PT): a liquid dye is applied to a metal surface, revealing cracks and surface imperfections.
- Ultrasonic Test( UT).
STATIC and DYNAMIC BALANCING
Turbine’s balance is essential, and it must be tested still and in motion to point out asymmetries and undistributed weight that might stress the bearing, thus increasing the wheel’s expected lifespan.
In case an anomaly is found, it is solved by adding or subtracting a counterbalancing weight.
When balancing a rotating body, vibration is to be avoided since it undermines the efficiency of hydro wheels and can sometimes lead to machine failure.
