IIW
The International Welding Practitioner (IWP) is the foundation (lowest) level of the four IIW welding-coordination diplomas, below the IWS, IWT and IWE. It is administered by the International Institute of Welding through the International Authorisation Board (IAB) and delivered by national Authorised Nominated Bodies (ANBs). Training is about 150 hours of theory and practical across four modules: Module 1 welding processes and equipment, Module 2 materials and their behaviour during welding, Module 3 construction and design, and Module 4 fabrication, applications engineering and quality. Assessment is by written module exams (multiple-choice and structured questions) with a minimum of 50% per module under IAB rules, plus a practical assessment at the practitioner level. Candidates enter via a standard training route or an alternative experience route of about four years. This free prep includes 100 research-based practice questions with explanations and an AI tutor.

1In the ISO 4063 numbering of welding processes, which process number designates manual metal arc welding with a covered electrode (MMA / SMAW)?
2In gas metal arc welding (GMAW), which metal-transfer mode produces the lowest heat input and is therefore preferred for thin sheet and positional welding?
3A welding power source is rated at 300 A at a 60% duty cycle. What does the 60% duty cycle mean?
4For TIG (GTAW) welding of plain carbon and stainless steels, which current type and polarity is normally used?
5Which shielding gas is used for TIG (GTAW) welding of carbon steel and stainless steel?
6Increasing the electrical stickout (contact-tip-to-work distance) in GMAW while keeping voltage and wire feed constant will normally:
7In submerged arc welding (SAW), the granular flux performs several functions. Which of the following is NOT a function of the SAW flux?
8What is the main purpose of the flux coating on a covered MMA (SMAW) electrode?
9Basic (low-hydrogen) MMA electrodes must be stored and handled carefully because their coating readily absorbs:
10Which welding process uses a non-consumable electrode?
About the IIW IWP Exam
The International Welding Practitioner (IWP) is the foundation level of the IIW welding-coordination diploma scheme administered by the International Authorisation Board (IAB). Training is about 150 hours of theory and practical, organised into four modules, and is assessed by written module exams plus a practical, with a minimum of 50% per module under IAB rules.

Frequently Asked Questions
What is the IIW International Welding Practitioner (IWP)?
The IWP is the foundation (lowest) level of the four IIW welding-coordination diplomas, below the IWS, IWT and IWE. It is administered by the International Institute of Welding through the International Authorisation Board (IAB) and delivered by national ANBs.
How is the IWP exam structured?
Training is split into four modules (processes, materials, design, and fabrication/quality) and is assessed by written module exams using multiple-choice and structured questions, plus a practical assessment at the practitioner level. Exact paper formats are set by each national ANB.
What score do I need to pass the IWP exams?
Under the IAB guideline a minimum of 50% must be achieved in each module, and failing a module blocks the award until it is passed. Some ANBs apply a higher pass mark, so confirm the requirement with your training body.
What topics does the IWP cover?
It covers Module 1 welding processes and equipment, Module 2 materials and their behaviour during welding, Module 3 construction and design, and Module 4 fabrication, applications engineering and quality, including weld defects, NDT, WPS/WPQR and welding safety.
How do I become eligible for the IWP?
You meet your national ANB access conditions and follow either the standard route (about 150 hours of approved training at an Approved Training Body) or the alternative route (about four years of relevant welding experience in a responsible role).
Is this free IWP practice as good as paid prep?
Our 100 practice questions cover the same four IIW modules at practitioner depth, with a teaching explanation for every answer plus free daily AI tutor interactions. All content is free forever and updated for 2026.
