Welding coordination: an IWE coordinator on your site
Green Engine provides IWE engineers who take on the welding coordination of your fabrication according to ISO 14731: at your premises, with your teams, for as long as you need.
The role of the welding coordinator
ISO 14731 sets out the tasks and responsibilities of welding coordination. The coordinator answers for the quality of welded joints, from the review of requirements to traceability:
- review of the contract and design requirements, technical review of drawings;
- choice of processes, filler materials and welding procedure specifications (WPS);
- qualification of welding procedures (WPQR) and of welders;
- preparation, supervision and inspection of welding operations;
- inspection and testing, handling of non-conformities and corrective actions;
- documentation and traceability of welded fabrication.
IWE, IWT, IWS: which coordinator level?
ISO 14731 distinguishes three levels of technical knowledge. The qualifications of the International Institute of Welding (IIW) match them:
| Level of knowledge in ISO 14731 | IIW qualification |
|---|---|
| Comprehensive technical knowledge | IWE, International Welding Engineer |
| Specific technical knowledge | IWT, International Welding Technologist |
| Basic technical knowledge | IWS, International Welding Specialist |
An IWE engineer has the most comprehensive level: he or she can hold a coordinator position required at IWT or IWS level. If your specification calls for an IWT coordinator, a Green Engine IWE engineer covers it.
Welding coordination in your sector
Wherever welding is governed by a standard or a code, a qualified coordinator is needed. Our IWE engineers work in every industrial sector:
Rail
Welding of railway vehicles and components to EN 15085, which requires a coordinator at level A, B or C depending on the certification level of the workshop; these levels correspond to the IWE, IWT and IWS qualifications.
Nuclear
Mechanical components of nuclear islands to the RCC-M code and the French nuclear pressure equipment regulations (ESPN): qualified procedures, welders and inspections, full traceability.
Oil, gas, chemicals and pressure equipment
Vessels and piping under the Pressure Equipment Directive (PED 2014/68/EU), EN 13445, EN 13480, CODAP or ASME (Section IX, B31.3); pipelines to API 1104.
Shipbuilding
Shipbuilding and offshore work, with procedure and welder qualifications approved by the classification societies (Bureau Veritas, DNV, Lloyd's Register…).
Wind energy
Towers, foundations and structures of onshore and offshore wind turbines, to EN 1090-2 and ISO 3834.
Aerospace
Welding of aerospace parts to ISO 24394 or AWS D17.1, and the requirements of Nadcap accreditation for welding.
Defence
Vehicles, weapons and equipment, with the quality requirements of defence prime contractors (NATO AQAP, ISO 3834).
Steel construction
Steel frames and structures to EN 1090-2, where the knowledge required of the coordinator depends on the execution class (EXC) and the steels.
How a coordination assignment works
Depending on what you need, a Green Engine IWE engineer can be:
- your welding coordinator for a given period: start of a new fabrication, absence or departure of your coordinator, peak of activity;
- a reinforcement of your existing coordination, on a project or at a supplier;
- support in preparing a certification or surveillance audit (ISO 3834, EN 15085, EN 1090);
- quality assurance of your suppliers: follow-up and inspection of the welded fabrication you subcontract, at their premises;
- acceptance of a fabrication: review of the manufacturing record, inspections and tests, check of conformity before shipment or installation;
- start-up and commissioning of equipment or an installation: follow-up of the welded joints made on site, clearing of the punch list.
Our engineers work on your sites, with your teams and to your schedules, on short assignments or long-term support, anywhere in France.
Frequently asked questions
What is a welding coordinator?
The person who answers, in the company, for the quality of welding operations: procedures, welders, equipment, inspection and traceability. The tasks and responsibilities are defined by ISO 14731.
What is the difference between an IWE and an IWT?
They are two IIW qualifications. The IWE (International Welding Engineer) matches the comprehensive technical knowledge of ISO 14731, the IWT (International Welding Technologist) the specific knowledge. An IWE can carry out IWT-level assignments.
Which sectors do you work in?
In every sector where welding is regulated: rail, nuclear, oil and gas, chemicals, shipbuilding, wind energy, aerospace, defence, pressure equipment, steel construction.
Do you work anywhere in France?
Yes. Green Engine is based in Ariège, in the Occitanie region, and its engineers work on their clients' sites throughout France, on short assignments or long-term support.
