Non-Destructive Testing (NDT)

Hi-Tek employs two full time Level III FPI Inspectors as well as an in-house metallurgical lab

Airflow testing is key to any successful turbine. In addition to confirming that the devices we fabricate function as intended and don't include defects, our wind-tunnel tests make it simpler to improve part performance. Hi-Tek clients don't have to deal with surprises in the field because we keep them informed on what to expect.

Hi-Tek has a met lab staffed with engineers that has decades of experience. Tests that are typically performed in the lab include failure testing, corrosion testing, chemical analysis, weld testing, and metallography

Thermal processes such as EDM, Laser, Material Joining, etc. have stringent requirements for such things as recast layer, heat affected zones, microcrack limits, etc. 


In 1985, Hi-Tek realized the need to have fully approved in-house Met Lab resources and established that capability. Since then the equipment has been continually updated to stay on the leading edge of the process. Hi-Tek maintains Met Lab approvals from all our customers as required.
