- welding coordination personnel shall have sufficient knowledge of welding and allied process
in general, and detailed knowledge of the assigned tasks.
Depending on the range and complexity of the products, on the dimension and the number of the
workshops, and on the relevance of the welding activities, the welding coordination personnel can
be directly employed by the Manufacturer or a consultant, however assuring adequate presence in
the company.
Typical tasks for the welding coordinator are reported as follows 6 :
- contract and design review;
- evaluation of weldability and relevant choice of base material (if applicable) and welding
consumables;
- assessment of possible Subcontractors;
- welding (and allied activities) production planning;
- equipment management;
- welding and testing (preliminary to final) activities;
- welding documents control and management of the ISO 3834 quality system.
This leads to the need of appropriate knowledge and experience, that shall comply with EN
719 / ISO 14731 requirements. In particular, three different levels of knowledge are considered:
1. comprehensive technical knowledge;
2. specific technical knowledge;
3. basic technical knowledge.
The level of knowledge shall be based on normative and contractual requirements or could be a
Manufacturer’s choice based on the range and on the complexity of the products, on the dimension
and the number of the workshops, on the relevance of the welding activities.
IIW provides for guidelines for the qualification of International Welding Engineers, Technologists
and Specialists, corresponding to the three above mentioned levels. IIW qualification guarantees
appropriate knowledge, but is not compulsory; therefore the Manufacturer can refer to any other
qualification, but shall, however, be prepared to demonstrate adequacy of such a qualification to
customers or certification bodies.
Concerning the experience, no specific requirement is given; two years of experience in the
specific field of the Manufacturer’s welded products are generally considered as sufficient, even if
experience should be at least proportional to the complexity of the welding production. EWF
provides for a three years based Certification programme for welding Engineers, Technologists
