AWS CWI Inspectors
Need an AWS Certified Welding Inspector (CWI) for an industrial fabrication or manufacturing project?
Dilenza identifies AWS CWI inspector profiles according to your equipment, welding processes, materials, applicable standards, inspection scope, supplier location and project schedule.
Profiles can support one critical inspection point, recurring welding surveillance or longer manufacturing programs.

What Is an AWS Certified Welding Inspector?
The Certified Welding Inspector (CWI) credential is issued by the American Welding Society and is widely used for welding inspection requirements on industrial fabrication and engineering projects.
AWS qualification requirements combine relevant education and welding-related work experience, visual acuity requirements and successful completion of the certification examinations.
The CWI examination evaluates areas including:
- Welding inspection fundamentals
- Practical inspection activities
- WPS and PQR application
- Inspection tools and methods
- Weld evaluation
- Understanding and use of applicable code requirements
AWS currently references AWS QC1 for certification requirements and AWS B5.1 for qualification of welding inspectors.
A CWI qualification provides an important technical credential. For an actual project, however, the inspector should also have relevant experience with the equipment and fabrication being inspected.

AWS CWI is the qualification. The project determines the right inspector.
When Is an AWS CWI Inspector Relevant?
An AWS CWI may be requested where:
The client specification requires AWS CWI certification
AWS welding requirements form part of the project documentation
Independent welding inspection is required
A purchaser requires qualified welding surveillance at a supplier
Structural fabrication requires defined welding inspection
Weld repairs need independent follow-up
An ITP identifies third-party welding inspection points
The project specifically requires an AWS-qualified inspector
The mandatory qualification should always come from the project specification, ITP, purchase order, applicable code or client requirement.
Do not select AWS CWI simply because welding is involved.
If the project does not specify the qualification, Dilenza can review the available documentation before profiles are considered.
What Can an AWS CWI Inspector Support?
The exact inspector responsibilities depend on the project. Where included within the agreed scope, AWS CWI inspectors may support welding inspection activities before, during and after fabrication.
Before Welding
Inspection may include:
- Welding Documentation
- Material Identification
- Traceability
- Joint Preparation
- Fit-Up
- Welder Qualifications
- Welding Consumables
This can include verification of project-defined requirements relating to WPSs, qualification documentation, joint configuration and preparation before production welding begins.
During Welding
Welding surveillance may include:
- WPS Compliance
- Welder Identification
- Welding Process
- Consumables
- Preheat
- Interpass Temperature
- Welding Sequence
- Production Conditions
The applicable requirements should always follow the controlled project documentation.
After Welding
Post-weld inspection can involve:
- Visual Examination
- Weld Dimensions
- Surface Condition
- NDT Status
- Repairs
- Documentation
- Project Acceptance Criteria
Where non-conformities or weld repairs are identified, follow-up inspection can also form part of the assignment.
WPS, PQR & Welder Qualification Review
Welding inspection is not limited to visually examining completed welds. Depending on the agreed project responsibilities, an AWS CWI can support verification of welding documentation such as:
WPS
Welding Procedure Specification
Is the correct approved procedure being used for the production welding activity?
PQR
Procedure Qualification Record
Does the supporting procedure qualification correspond to the project-defined requirements?
Welder Qualification
Welder Performance
Are the welders performing the work appropriately qualified for the production welding they are carrying out?
Weld Traceability
Where required, traceability may connect:
- Drawing
- Weld Number
- WPS
- Welder
- NDT
- Repair Status
The exact responsibilities depend on the applicable code and project documentation.
Not Every AWS CWI Has the Same Experience
Two inspectors can hold the same AWS CWI qualification and still have very different technical backgrounds.
One may have extensive experience with: Structural Steel
while another may specialize in: Pressure Equipment · Piping · Shipbuilding · Heavy Machinery
Materials and welding processes can create further differences.
That is why Dilenza does not select an AWS CWI based only on the certificate.
Inspector matching can consider:
- Equipment
- Industry
- Materials
- Welding Processes
- Applicable Standards
- Inspection Responsibilities
- Previous Project Experience
Certification confirms qualification. Experience determines relevance.
AWS CWI Profiles for Industrial Fabrication
Depending on the project and available profiles, AWS CWI inspectors can be considered for welded equipment such as:
Structural Steel
- Frames
- Platforms
- Modules
- Buildings
- Support Structures
- Heavy Welded Assemblies
Requirements may involve fit-up, welding surveillance, visual inspection, NDT status and repair verification.
Pressure Equipment & Piping
- Pressure Vessels
- Heat Exchangers
- Tanks
- Piping
- Skids
- Process Equipment
Inspector selection should consider experience with pressure equipment, materials, welding processes and the applicable project requirements.
Shipbuilding & Marine Fabrication
- Vessel Structures
- Ship Blocks
- Marine Equipment
- Offshore Structures
- Marine Piping
For marine projects, relevant shipbuilding or marine fabrication experience can be an important selection criterion.
Machinery & Heavy Fabrication
- Industrial Machinery
- Equipment Frames
- Fabricated Assemblies
- Heavy Welded Components
The inspector profile can be matched according to the actual machinery and fabrication involved.
AWS CWI Does Not Mean AWS D1.1 Only
An AWS CWI is an inspector qualification—not a single welding code.
Projects involving AWS CWI inspectors may operate under different controlled standards depending on the equipment and contractual requirements.
If the project requirement is specifically AWS D1.1 rather than simply an AWS CWI qualification, see our AWS D1.1 Welding Inspection Services.
These can include:
- AWS
- ASME
- API
- ISO
- EN
- Client Specifications
- EPC Specifications
AWS itself allows CWI candidates to demonstrate code-book competence across several code routes, including AWS structural welding codes, API 1104, ASME requirements and ISO-based examination options.
For an actual inspection assignment, the correct:
- Standard
- Edition
- Acceptance Criteria
- Inspector Responsibility
must come from the project's controlled documentation.
Qualification and applicable code are two separate project requirements.
AWS CWI Inspectors Where Your Project Needs Them
Industrial fabrication may take place far from the purchaser or final project site.
Dilenza can review AWS CWI inspection requirements across major manufacturing and industrial regions worldwide.
Typical assignments may take place at:
- Manufacturers
- Fabrication Facilities
- Shipyards
- Equipment Suppliers
- Industrial Project Sites
Requirements can be reviewed according to:
- Location
- Equipment
- Qualification
- Scope
- Date
- Duration

AWS CWI Assignment Models
AWS CWI requirements do not always involve the same level of presence.
One Visit
For one defined activity such as:
- Fit-Up
- Hold Point
- Welding Activity
- Repair Verification
- Final Weld Inspection
Recurring Inspection
Repeated welding inspection throughout fabrication.
Useful where welding, NDT and repair activities occur across multiple manufacturing stages.
Resident Inspection
Frequent or continuous technical presence for longer fabrication programs.
Multi-Site Inspection
AWS CWI inspection coordinated across several manufacturers contributing welded equipment to the same project.
Review the Inspector Before Deployment
Where appropriate, Dilenza can submit relevant inspector information for client technical assessment before confirmation.
This can include:
- AWS CWI certification
- CV
- Welding inspection experience
- Relevant equipment experience
- Industry background
- Additional qualifications
- Availability
If your project defines mandatory experience—such as pressure vessels, structural steel, shipbuilding or specific materials—include it in the request.
