Non-Destructive Testing is the discipline that verifies material integrity without damaging the asset. On capital projects, the credibility of every NDT result depends on three things: qualified personnel, calibrated equipment, and engineering governance. Qualitech delivers all three, coordinating certified NDT specialists under our technical oversight so every report is defensible, traceable, and integrated into your project documentation architecture.
NDT services require certified technicians, calibrated equipment, and recognized accreditations that are specialized, capital-intensive, and dedicated. Rather than building redundant in-house capacity, Qualitech partners with vetted NDT specialists who deliver the field execution. We deliver the engineering oversight, technique selection, acceptance criteria, report validation, and integration into your quality architecture.
The client interacts with Qualitech. The scope, technique, procedure, and acceptance criteria are engineered by Qualitech. The field execution is performed by our qualified partner. The results are validated, governed, and delivered to you as a single, unified quality output, fully traceable to the ITP item, asset, drawing, and regulatory requirement.
Each NDT method detects specific defect types in specific materials. The engineering judgment is choosing the right method (or combination of methods) for each inspection point on your project. That judgment comes from Qualitech.
Detection of surface-breaking defects in non-porous materials. A liquid dye is applied to the surface, drawn into any open discontinuity by capillary action, then made visible by a developer. Effective for detecting cracks, laps, seams, porosity, and laminations on welds, castings, forgings, and machined surfaces of ferrous and non-ferrous metals, ceramics, and plastics.
Detection of surface and near-surface discontinuities in ferromagnetic materials. The component is magnetized and iron particles are applied to the surface. Discontinuities disrupt the magnetic field, attracting particles that reveal the defect. Standard method for welds in carbon steel, structural fabrications, pressure vessels, and pipeline construction.
Volumetric detection of internal flaws using high-frequency sound waves. A transducer sends pulses into the material; reflected signals reveal internal discontinuities and their depth, size, and orientation. Used for weld inspection, thickness measurement, lamination detection in plates, and integrity assessment of pressure vessels, pipelines, and structural components.
Advanced ultrasonic inspection using multi-element probes that electronically steer, focus, and scan the beam. Generates detailed sectoral and linear images of weld volumes. Delivers higher probability of detection, faster scan speeds, and visual data that supports engineering review. Preferred method for critical welds in pressure piping, nuclear, and pipeline girth welds, where RT alternatives are restricted.
Qualitech engineers select the appropriate NDT method for each inspection point based on material, geometry, access, code requirements, and defect criticality. Written procedures aligned with ASME V, AWS D1.1, API 1104, and project specifications.
All partner NDT technicians qualified to ASNT SNT-TC-1A or CP-189 (Level II minimum for execution, Level III for interpretation). Qualification records collected, verified, and filed in project quality documentation.
Calibration blocks and reference standards verified before each inspection campaign. Equipment certifications validated. Calibration records attached to every NDT report for full audit defensibility.
Qualitech representatives oversee field execution at critical hold points, verifying technique compliance, surface preparation, and evidence capture. Photos, measurements, and environmental data recorded alongside NDT results.
Every NDT report reviewed by Qualitech Level III or senior engineer before delivery to the client. Acceptance criteria verified. Indications classified. Rejections, repairs, and reinspections tracked to closure in the project quality system.
NDT reports linked to the correct ITP item, weld number, tag, drawing, and system. Integrated into digital quality system and progressively indexed into the turnover package. No loose PDFs. No fragmented records.
The partner-delivered model is not outsourcing. It is engineered coordination. Three reasons it delivers better outcomes than in-house or uncoordinated subcontracting.
NDT partners maintain focused competency: certified technicians, calibrated equipment, current accreditations, and daily field experience. Qualitech maintains focused competency in engineering governance, technique selection, and project integration. Neither tries to do the other's job.
You interact with Qualitech. One contract. One reporting chain. One source of truth. Partner coordination, procedure alignment, scheduling, and deliverable integration happen behind the scenes. Your project team is not managing a subcontractor. Qualitech is.
NDT reports are not loose PDFs. They are data points inside your quality architecture, linked to ITP items, welds, drawings, and assets. Indexed for turnover. Searchable by any regulator or auditor, decades from now. That integration is the partner model's most tangible deliverable.
You pay for the specialized capability when you need it, at the scale you need it. No idle in-house crews between campaigns. No project overhead absorbing dedicated NDT staff. The partner model scales up and down with your project's actual inspection demand.
