Third-Party Welding Inspection for Owners & Contractors
Integrated Inspection LLC provides third party welding inspection that keeps projects moving. As a neutral partner, we deliver independent welding inspection to verify code requirements, document conformance, and help teams resolve issues quickly. Our AWS CWI-led crews bring practical, field-proven oversight, mobile NDT, and clear reporting across heavy civil, structural, and industrial environments.
Why third-party inspection matters
Third party welding inspection adds objective, code-based verification to your QA/QC plan. Bringing in an outside CWI provides separation from production pressures and creates confidence for owners, engineers, and authorities having jurisdiction.
Typical triggers for independent oversight
- Owner requirements written into contract documents
- Critical weld categories, fracture critical members, or pressure boundaries
- New or revised WPS/PQR or procedure changes
- Inspector workload spikes or need for specialized NDT methods
- Closeout packages that demand independent certification
What owners and contractors gain
- A clear path to acceptance via code compliant inspection and documentation
- Faster issue resolution with practical, field-ready recommendations
- Reduced rework through early discovery and real-time feedback
- Credibility with stakeholders through a certified third party inspector
Where we fit on your project team
Owner's rep QA/QC coverage
We act as your quality partner on site, verifying hold points, witnessing fit-up, monitoring preheat/interpass, and confirming final acceptance. Our reports and photo logs support payment milestones and change-management decisions.
Contractor and fabricator support
When schedules compress, we augment your in-house QA with additional CWI and NDT capacity. Use us to help qualify welders and procedures, clear punch lists, and close documentation gaps without slowing production.
Heavy civil and industrial coverage
From bridges and utilities to plants and pipelines, we support heavy civil welding inspection and industrial weld inspection with practical, code-driven execution.
Bridges, DOT, and infrastructure
- Field welding for steel girders, cross-frames, and diaphragms
- Bearing, connection, and stiffener welds under DOT oversight
- Coordination with owner reps and CM firms for hold-point verification
For dedicated support, see our Bridge & DOT Inspection services.
Plants, tanks, piping, and vessels
- Structural, pipe, and pressure boundary welds in operating facilities
- Tank floors/shells, nozzles, and appurtenances under API guidance
- Turnarounds, outages, and tie-ins with tight windows

Codes, credentials, and compliance
Our inspectors work to the governing standard and jurisdictional requirements your project specifies.
Code sets we work under
- AWS D1.1/D1.5 and relevant AWS structural/bridge codes
- ASME Sections and B31 piping series as applicable
- AISC quality provisions
- API 510/570/653 scopes
- MDOT and DSA requirements when projects demand
This ensures consistent, code compliant inspection aligned with contract documents and submittals.
Certified inspectors and NDT levels
Teams include AWS CWI/CWE, ASNT Level II/III, and ICC Special Inspector credentials. When you need a certified third party inspector to sign reports, witness PQR/WPQ activity, or confirm acceptance, we provide credentialed coverage backed by clear, traceable records.
Scope of services and methods
We combine visual inspection with the right NDT to confirm quality at each phase of work.
Welding inspection and visual VT
- Fit-up, joint preparation, and consumables control
- Preheat/interpass monitoring and parameter verification
- In-process and final visual acceptance to governing code
Learn more on our visual inspection page.
NDT methods available on site
- Ultrasonic Testing for weld discontinuities and thickness
- Radiographic (X-ray) Testing for volumetric weld quality
- Magnetic Particle Testing for surface/near-surface indications in ferromagnetic materials
- Dye Penetrant Testing for fine surface-breaking indications
We tailor methods to geometry, accessibility, and code acceptance criteria.
Mobilization, safety, and documentation
We support tight schedules with mobile units, practical safety controls, and organized reporting.
Rapid field response and coverage
We mobilize quickly across Michigan, Indiana, Ohio, and Illinois, and travel nationwide as projects require. Crews arrive prepared with calibrated instruments, consumables, and forms to minimize site time.
Safety and radiation compliance
Our team maintains DOT drug/alcohol testing, OSHA 30, and radiation safety compliance. Procedures consider restricted spaces, energized areas, lifting plans, and site-specific orientations.
Reporting and turnover packages
Deliverables include daily reports, indication maps, photo documentation, and code-referenced acceptance statements. We align with your submittal structure so turnover packages pass reviews without delay.
Owner-rep and contractor QA support
Whether embedded full-time or spot-checking critical welds, we provide owner rep welding inspection and contractor QA coverage that scales with the job. As an independent partner, we document compliance, communicate issues clearly, and keep decisions grounded in code language and approved procedures.

FAQs: third-party welding inspection
Why hire a third-party welding inspector?
To gain objective, code-based verification from an independent party. This improves stakeholder confidence, reduces rework, and helps projects meet schedule and compliance requirements.
Do you support owner-rep or contractor QA needs?
Yes. We support both owner-rep programs and contractors/fabricators that need additional CWI and NDT capacity, documentation support, and acceptance verification.
Can you cover active civil and industrial projects?
Yes. We support bridge/DOT, structural steel, tanks, piping, pressure vessels, utilities, and plant work, with mobile field coverage and practical coordination.
Which codes do you inspect to?
We work under AWS, ASME, AISC, API, MDOT, and DSA requirements as specified in your contract documents and submittals.
How fast can you mobilize?
We prioritize rapid turnaround across the Midwest and travel nationwide as projects require. Share your schedule and constraints, and we will propose a mobilization plan.
What documentation do you provide?
Daily inspection reports, NDT results, photo logs, indication maps, and code-referenced acceptance statements organized for submittal and closeout.
