CPF2 Site PVV - Welding QC Inspector

IOTA GROUP

Daily Inspection & Reporting

• Monitor and record all welding activities on a daily basis.
• Conduct routine inspections in fabrication areas, pipe racks, vessel installation zones, and field welding locations.
• Verify that welding activities follow approved procedures and are performed by qualified welders.
• Verify the contractor s daily welding reports and associated databases
• Review weekly trends of weld acceptance / rejection.
• Provide daily update and weekly reporting directly to the CPF2 Site QC Superintendent, covering: inspection progress and key findings, non-conformities and recurring defects, critical issues requiring escalation or arbitration, status of corrective actions, quality trends and contractor performance indicators.
• Contribute actively to daily/weekly QC coordination meetings and ensure the QC Superintendent receives all relevant data for consolidated site reporting.
• Maintain up-to-date records, ITP follow-up, NCR/CAR tracking, and Mechanical Completion documentation enabling full visibility for the QC Superintendent.

Welding & Fabrication Inspection PVV Scope
Welding Activities

• Verify material identification and traceability ensuring compliance with project specificationsand MTC requirements.
• Verify joint preparation, bevels, fit-up, alignment, and cleanliness before welding.
• Ensure compliance with approved WPS, PQR, and welder qualifications (WPQ).
• Monitor welding parameters, heat input, pre-heat, interpass temperature, and cooling.
• Verify consumables storage, handling, baking, and traceability.
• Verify weather protection arrangements during field welding.
• Check shielding gas selection and purge practices for SS/DSS.
• Inspect and verify distortion control practices implemented by contractor.
• Verify flange rotation, bolt hole alignment, and nozzle orientation
• Review PWHT procedures, thermocouple placement, and heat charts.
• Inspect weld appearance, bead profile, and dimensional tolerances.
• Validate weld numbering, weld mapping, and traceability records.
• Ensure weld repairs follow approved repair procedures and are properly documented

PVV Equipment Covered

• Process piping (CS, LTCS, SS, DSS, SDSS, Alloy, CRA)
• Pressure vessels (nozzles, skirts, attachments, supports)
• Valves (pup pieces, welded connections, orientation welds)
• Static equipment requiring welded connections
• Vendor packaged skids and vessels including associated welded piping and supports.
• Verify welded structural interfaces connected to PVV systems

Interfaces With NDT

• Ensuring NDT requirements are correctly identified in ITPs and WPS.
• Verifying welds are properly prepared for NDT (cleaning, access, marking).
• Ensuring repairs requested by NDT are executed correctly.
• Reviewing NDT reports for completeness and compliance.

Interfaces With QC Piping

• Ensure weld joints are correctly identified and belong to the proper line/system before welding.
• Align with QC Piping on fit-up release, ITP hold/witness points, and readiness for welding.
• Provide QC Piping with weld traceability information (weld numbers, WPS, welder IDs).
• Support QC Piping during system walkdowns for weld-related verifications.
• Deliver welding documentation required for piping test packs and Mechanical Completion dossiers.
• Communicate welding issues that may impact piping installation sequence or system readiness.
• Verify weld-related punch items are addressed before required turnover and confirm welding readiness prior to hydrotest.

Documentation & Compliance

• Review and comment on welding procedures (WPS), PQR, and welder qualifications.
• Ensure proper implementation of approved drawings, welding plans, and ITPs.
• Verify welding records, consumable certificates, and traceability documentation.
• Issue Quality Records, NCRs, and CARs when required.
• Maintain accurate welding documentation for Mechanical Completion and MDR preparation.

Non-Conformities & Corrective Actions

• Identify and report welding nonconformities or deviations.
• Ensure corrective actions and weld repairs are implemented and verified.
• Monitor recurrence of weld defects, advice preventive actions and participate in root cause analysis for welding issues.
• Immediately escalate critical anomalies to the QC Superintendent.

Coordination & Interface

• Participate in daily/weekly QC and construction coordination meetings.
• Interface with QC Piping, QC Mechanical, QC NDT, Engineering, and Contractor welding teams.
• Support technical clarifications related to welding and metallurgy.
• Participate in audits (Construction, HSE, QC) and site visits.
• Ensure confidentiality of all documentation under responsibility.
