IIW International Welder (IIW)


The International Institute of Welding (IIW) has adopted the International Welder (IW) programme to address the need for highly skilled welders and to achieve global harmonisation in the training, examination and qualification testing of welders.

Training and assessment in the IIW programme are linked to the requirements of the international standard, ISO 9606 qualification testing of welders. The ISO 9606 standard is widely used in South Africa, but it is important to note that it is similar to other standards, which are relevant in South Africa, eg. ASME IX and AWS D1.1.

The IIW programme provides a combination of theoretical knowledge and high-level practical skills assessed by tests of increasing difficulty and by theoretical examinations.

The programme is presented at three levels – fillet, plate, and pipe welder. Trainees are required to start with fillet welding and must pass a practical competency test before progressing to the next level. Training periods for practical welding vary from person to person.

Experienced welders are not required to undertake unnecessary practical training and may enter the IW programme at any level subject to completing the relevant level practical qualification test including those required for lower levels. A welder fully competent in fillet, plate and pipe welding would undertake the practical test for all three levels and would then undertake only the relevant theory components.

It is important that at each level there is an associated level of theory, plus there may be process specific and material specific theory modules which are applicable.

Entry Requirements

  • Good hand-eye coordination is the most important aspect to allow one to excel in welding.
  • Appropriate health as well as physical and mental capability is required to enter at Fillet Welder level.
  • Access to higher levels may be allowed upon passing of relevant theoretical examinations and demonstration of required practical skill.




The estimated time required for the various processes and levels is shown below, but this is dependent on the individual’s aptitude.

Should the individual complete a process and level early credit will be given to contribute to the next level or process.

The above pricing includes practical welding training, welder certification testing (coding), theoretical training and examination fees. IIW Diploma after successful completion of the course

A 25% surcharge is applied if the material is stainless steel or aluminium.

Should only a welder competency test be required, R3 280 will be charged per welding process, per position, per material.


The theory modules and welder qualification tests are included in the price of the International Welder qualification programme. However, an experienced welder may wish to become an International Welder through recognition of prior learning. In this case, the theory modules and welder qualification tests can be taken separately to the practical training:
