IIW IWI-S

Expect a mix of multiple-choice questions, written or essay-type answers requiring justification of acceptance decisions, and practical inspection exercises where you examine samples and report findings. The exact structure and weighting are set by the awarding body and its national member societies, so confirm the current scheme description with them before booking.

It is the entry level of the IIW inspector ladder, below the comprehensive and international levels. The breadth is still significant: you need working knowledge of processes, metallurgy, design, NDT and quality systems. Candidates with shop-floor welding or QC experience generally find it manageable; those coming from purely academic backgrounds need extra practical exposure.

Most candidates follow an approved training course rather than self-study alone. Between course attendance and revision, plan several months of part-time work, with extra time for NDT interpretation and report writing if those are new to you. Your national body publishes the required training hours and any experience prerequisites for entry.

Retake rules, waiting periods and any limits on attempts are defined by the awarding body and the national organisation administering your examination. Ask them directly before you register, and request the policy in writing, because conditions can differ between countries and can change between examination sessions.

Start with processes and materials, since inspection criteria only make sense once you understand how a joint is made and how it can fail. Then cover design and fabrication, followed by inspection and testing, which carries the heaviest weighting. Finish with quality management, safety and reporting, and practise integrating everything through mock inspection scenarios.

Weak justification rather than weak recall. Candidates list a defect but cannot cite the acceptance criterion, confuse welding procedure qualification with operator qualification, or misread NDT indications. Poor report writing - missing locations, sizes, standards referenced or clear accept/reject conclusions - also costs marks in the practical and written parts.

It is not usually a formal requirement for the Standard level, but it helps enormously. Having seen real welds, preheat practice, distortion and common defects makes acceptance criteria intuitive. If you lack it, arrange shop visits or supervised inspection practice so you can recognise what you are being asked to evaluate.

You should be able to work through a welding procedure specification, its qualification record, a drawing with weld symbols, a quality plan and an inspection and test plan, and the acceptance criteria of the applicable standard. Practise extracting the essential variables and checking whether production welding actually follows the approved procedure.

These are published by the International Institute of Welding and by the authorised national body or member society that delivers the qualification in your country. Check their official websites for the current scheme documents, fee schedules and examination calendars; do not rely on training providers' summaries or forum posts.
