Our Services

WELDING INSPECTION

Welding Inspection & Third-Party NDT Services

API • AWS • ASME Code Compliance

We provide professional welding inspection and third-party NDT services supporting API, AWS, and ASME code compliance for industrial, infrastructure, and government-funded projects. Our inspection services focus on weld quality, safety, and regulatory compliance while minimizing risk, rework, and project delays.

On-Site Welding Inspection

On-site welding inspections are performed at fabrication shops and job sites to verify compliance with approved Welding Procedure Specifications (WPS), Procedure Qualification Records (PQR), material traceability, joint fit-up, preheat and interpass temperature control, and post-weld heat treatment requirements. All inspections are conducted in accordance with applicable API, AWS, and ASME codes.

Visual Testing (VT)

Visual Testing (VT) is a primary non-destructive testing (NDT) method used to evaluate weld quality and workmanship. VT inspections identify surface discontinuities such as cracks, porosity, undercut, overlap, and incomplete fusion in accordance with applicable AWS, ASME, and API acceptance criteria.

Dye Penetrant Testing (PT)

Dye Penetrant Testing (PT) is a non-destructive examination method used to detect surface-breaking defects in welds and base materials. PT is performed in accordance with applicable AWS and ASME standards and is effective for identifying fine cracks, laps, and porosity not detectable by visual inspection alone.

Quality Assurance & Quality Control (QA/QC)

Our QA/QC services support consistent weld quality and full compliance with project specifications and governing codes. QA/QC activities include review and verification of WPS and PQR documentation, welder qualifications, material certifications, inspection and test plans (ITPs), and NDT records. Structured QA/QC oversight ensures traceability, documentation accuracy, and readiness for audits and regulatory review on API, AWS, ASME, and government-regulated projects.

Independent Third-Party Weld Inspection for Government Contracts

We provide independent third-party welding inspection services for government, municipal, and federally funded projects requiring objective verification of weld quality and code compliance. Our inspections meet API, AWS, and ASME requirements and deliver unbiased reporting, traceability, and documentation required for contract compliance, audits, and regulatory oversight. Third-party inspection reduces liability, increases transparency, and supports successful project execution.

Commercial & Industrial Welding and Fabrication Services

We provide professional welding and fabrication services for commercial and industrial applications, delivering strong, precise, and code-compliant results. Our certified welders specialize in structural welding, custom metal fabrication, and industrial repairs, working with carbon steel, stainless steel, aluminum, and specialty alloys.

From new construction to equipment repair and plant modifications, we support demanding environments with MIG, TIG, and Stick welding performed to AWS, ASME, and project-specific requirements. Our team offers both shop and on-site welding services, ensuring minimal downtime and dependable turnaround.

Trusted by commercial contractors and industrial facilities, we deliver reliable workmanship, safety-focused execution, and fabrication solutions built to perform.

WPS DEVELOPENT AND QUALIFICATION

Welding Procedure Specification (WPS) & Procedure Qualification (PQR) Services

CWI Services, LLC delivers end-to-end welding procedure development, qualification, and code compliance support for fabrication, construction, and industrial projects across the United States. Our certified welding professionals develop technically sound, fully documented welding procedures that meet ASME, AWS, API, and project-specific code requirements, reducing risk, improving weld quality, and accelerating approvals.

Welding Procedure Specification (WPS) Development

We develop custom, code-compliant Welding Procedure Specifications (WPSs) engineered for repeatable, high-quality welds in real-world production environments. Each WPS is built around your materials, joint design, welding process, and service conditions.

Our WPS development includes:

  • Welding process selection (SMAW, GTAW, GMAW, FCAW, SAW, etc.)

  • Base material and filler metal compatibility

  • Joint design, welding positions, and progression

  • Electrical parameters (amperage, voltage, travel speed)

  • Shielding gas composition and flow rates

  • Preheat, interpass temperature, and post-weld heat treatment (PWHT)

  • Essential, supplementary essential, and nonessential variables per applicable code

All WPS documents are prepared to comply with ASME Section IX, AWS D1.1/D1.5/D1.6, API 1104, and other governing standards as required.

WPS Writing & Technical Documentation

Clear documentation is critical to fabrication success. Our team produces professionally written, audit-ready WPS documentation that is easy for welders to follow and inspectors to verify.

We ensure:

  • Complete technical detail and traceability

  • Clear formatting aligned with industry best practices

  • Full alignment with supporting PQR data

  • Documentation suitable for client, third-party, or regulatory review

This reduces shop errors, minimizes rework, and supports consistent welder performance.

Procedure Qualification Record (PQR) Development

CWI Services provides full PQR development and oversight, ensuring your welding procedures are properly qualified and defensible under code.

Our PQR services include:

  • Qualification test planning and variable control

  • Test coupon preparation and welding supervision

  • Recording of all required welding parameters

  • Verification of essential and supplementary essential variables

  • Compilation of complete PQR documentation

Each PQR validates that the proposed WPS can produce welds with acceptable mechanical and metallurgical properties.

Welding Procedure Qualification Testing

We coordinate and manage destructive and non-destructive testing required for procedure qualification, working with accredited testing laboratories to ensure accurate, code-compliant results.

Testing services include:

  • Visual inspection (VT)

  • Mechanical testing (tension, guided bend)

  • Impact testing (Charpy V-Notch), when required

  • Additional NDE as specified by code or client requirements

All test results are reviewed and incorporated into final PQR documentation.

Welding Engineering Consultation & Code Compliance Support

Our certified welding inspectors and welding specialists provide expert consultation to support challenging applications and compliance concerns.

We assist with:

  • Code interpretation and applicability

  • Material selection and weldability analysis

  • Welding process optimization

  • Addressing nonconformances and procedure revisions

  • Owner, engineer, and third-party coordination
