Welding Inspection
Quality Welds. Verified. Protected.
Welding Inspection Services
At Clearscope, we provide comprehensive welding inspection services to clients across Ireland and internationally, ensuring full compliance with EN, ISO and other relevant standards.
Welding inspection is a critical quality assurance process carried out before, during, and after fabrication to verify that all welds meet specified safety, quality, and regulatory requirements. For steel fabricators, structural contractors, and manufacturers, this is not optional — it is essential for CE marking, project eligibility, and risk management.
Failure to meet these requirements can have serious consequences. Unsuccessful audits can halt production, while undetected weld defects may compromise structural integrity, leading to costly rework, project delays, and potential liability exposure. Early detection is key — the sooner issues are identified, the safer and more cost-effective the outcome.
Our inspectors are both CSWIP and PCN qualified, bringing extensive hands-on fabrication experience to every project. We work proactively to identify defects at the earliest stage and support your team in understanding root causes, helping prevent recurrence and reducing costly late-stage repairs.
Inspection Checklist for Connection Welding
A structured inspection approach to ensure welding quality, structural integrity and long-term coating performance.

- No visible cracks or lack of fusion
- Undercut within limits
- No excessive porosity
- Surface finish acceptable
- Dimensional accuracy
- Non-destructive testing planned
- Final cleaning completed
WPS vs PQR
WPS defines how welding is to be done. PQR proves it works. Together, they ensure every weld is safe, reliable, and code-compliant.

How Clearscope Helps
What we deliver — specific, practical, and built to hold up under audit.
WPS & PQR Development
We develop, review, and qualify your Welding Procedure Specifications and Procedure Qualification Records to ISO 15614 and ASME Section IX.
Welder Qualification Testing
Qualification and re-qualification of welders and welding operators to ISO 9606 and EN 287, with full documentation for audit.
Production Monitoring
In-process inspection during fabrication — verifying welding parameters, inter-pass temperatures, and compliance with the approved WPS.
Defect Reporting & Root Cause
Detailed defect identification and root cause analysis so your welders understand what went wrong and how to prevent recurrence.
NDT Coordination
We specify, schedule, and manage the NDT programme for your project — ensuring the right methods are applied at the right stages.
