Verifying Form, Fit, and Function Before Shipment

Our testing services are a final quality gate designed to provide you with complete confidence before your project leaves our facility. We validate complex fabrications against your engineering models and performance requirements, preventing costly on-site modifications, installation delays, and commissioning challenges.

Trial Fit Verification

We assemble mating components, large-scale weldments, and complex systems in our dedicated assembly bays. This process physically verifies critical interfaces, hole patterns, clearances, and overall dimensional accuracy, guaranteeing that every part fits together precisely as designed.

Functional Testing

For dynamic assemblies, we go beyond static fits to test operational mechanics. This can include verifying the range of motion for moving parts, confirming the performance of integrated motors and pneumatic systems, and conducting pressure or leak testing to ensure system integrity.

Advanced Technology for Definitive Verification

We leverage state-of-the-art inspection technology and deep in-house expertise to provide objective, data-driven proof of compliance. Our quality team, including an on-staff Certified Welding Inspector (CWI) and personnel certified to ASNT SNT-TC-1A Level III, oversees the entire process.

3D Laser Scanning

Using our Leica AT960 Tracker, we perform high-precision, non-contact 3D scans of large components and assemblies for direct comparison against your CAD models.

3D Model-Based Inspection

We validate parts directly against your 3D models, ensuring every dimension and geometric tolerance is met.

Pressure & Hydro Testing

We conduct hydrostatic and pressure testing to verify the strength and leak-proof integrity of tanks and pressure-retaining components.

Specialized Weld Testing

We can perform Dye Penetrant Testing (PT), Vacuum Box Testing, and Ferrite Testing to ensure weld quality meets the most stringent standards.
