What We Do
Non-Destructive Testing Services
Six core NDT methods delivered by certified inspectors — available 24/7 across all major Texas markets.
Visual Weld Inspection
Certified inspectors perform thorough visual assessments to identify surface defects and ensure welds meet code requirements before any advanced NDT is applied.
VT DetailsRadiographic Testing
X-ray and gamma-ray imaging detects internal discontinuities in welds and base materials without damaging the structure, providing a permanent film or digital record.
RT DetailsUltrasonic Testing
High-frequency sound waves detect internal flaws, measure wall thickness, and evaluate weld quality with sub-millimeter precision across all material types.
UT DetailsMagnetic Particle Testing
Surface and near-surface defect detection using magnetic fields and ferromagnetic particles — ideal for ferrous welds, castings, and forgings.
MT DetailsLiquid Penetrant Testing
Capillary-action dye reveals surface-breaking discontinuities in non-porous materials, applicable to welds, castings, and machined components.
PT DetailsPositive Material Identification
Handheld XRF analyzers verify alloy composition on-site, ensuring the correct materials are used in pressure vessels, piping, and critical structural applications.
PMI DetailsWhy It Matters
NDT Protects People, Assets, and Compliance
Non-destructive testing is the only way to evaluate the integrity of welds, materials, and structures without taking them out of service or destroying them. The stakes are high: an undetected flaw in a pressure vessel or pipeline can result in catastrophic failure, injury, and regulatory shutdown.
Arc Inspection Services brings certified expertise and the right method for every application — so you can move forward with confidence that your assets are safe, compliant, and built to last.
