Function: Non-Destructive Testing and Weld Quality
Reports to: NDT Level III / QA/QC Engineer
Supervises: NDT technicians, where authorised
Role Purpose
Perform, witness, and review non-destructive testing of welds, materials, and equipment, ensuring methods, personnel, procedures, equipment, interpretation, and records meet the approved code and project acceptance criteria.
Key Responsibilities
- Review NDT procedures, technique sheets, examination coverage, acceptance criteria, drawings, weld maps, and inspection requests before testing.
- Verify technician certification, visual acuity, method authorisation, equipment calibration, reference standards, consumables, and environmental conditions.
- Perform or witness VT, PT, MT, UT and radiographic-film interpretation within certified competence and employer authorisation.
- Confirm surface condition, examination stage, identification, orientation, datum, scanning pattern, sensitivity, coverage, and traceability.
- Interpret indications accurately, distinguish relevant from non-relevant responses, and evaluate results against the specified code.
- Issue clear NDT reports with weld/component identity, method, equipment, calibration, coverage, indication details, disposition, and examiner approval.
- Maintain weld/NDT status, repair-cycle traceability, rejection trends, and release status so unaccepted work is not coated, tested, or concealed.
- Monitor radiation-safety interfaces for radiography and coordinate exclusion zones and permits with the authorised radiation team.
- Escalate ambiguous, significant, recurring, or out-of-scope indications to the responsible Level III and support root-cause and repair verification.
Qualifications and Experience
Minimum Requirements
- Technical diploma/HND or bachelor’s degree in Engineering, Materials, Welding, or a related technical discipline.
- Typically 5 or more years of industrial NDT experience on welds, piping, pipelines, tanks, structures, or pressure equipment.
- Current employer authorisation and documented experience for each method performed or interpreted.
- Ability to read weld maps, isometrics, drawings, NDT procedures, and code acceptance criteria.
- Strong attention to indication evaluation, report accuracy, and traceability.
Preferred Certifications and Standards Knowledge
- ASNT SNT-TC-1A, ASNT CP-189, ISO 9712, or equivalent Level II certification in the required methods.
- Radiographic-film interpretation certification/authorisation where film review is part of the role.
- Knowledge of ASME Section V/IX, ASME B31 series, AWS D1.1, API 650/653/570, ASTM E165/E709, and project-specific acceptance criteria as applicable.
Core Competencies
- NDT method execution and interpretation
- Procedure and calibration compliance
- Indication evaluation and code acceptance
- Weld-status and repair-cycle traceability
- Radiation-safety interface awareness
Key Performance Measures
- NDT completed within inspection schedule
- Reports accepted without traceability or interpretation errors
- No unauthorised release of rejected or unexamined work
- Repair and rejection trends reported promptly
- Calibration and personnel certification maintained without lapse
Reporting and Interfaces
Internal interfaces: Welding, QC, construction, pipeline/tank inspection, materials, HSE, and document control teams.
External interfaces: Client inspectors, NDT contractors, laboratories, radiation-safety personnel, and Level III authorities.
