Does your organisation need a named welding coordinator? Scope decision flow for ISO 14731, the personnel standards it sits beside, and the records an appointment has to produce.
ISO 14731 governs a role, not a weld. It sets out the welding-quality tasks a manufacturer has to assign — contract review, procedure control, personnel competence, production supervision, inspection, equipment control, deviation disposition — and requires each one to have a named owner with defined authority. What it does not do is hand out a universal answer for who that owner should be, which is exactly where appointments fail audit: a name on an organisation chart with no matching authority, no current competence review, and no production record the coordinator can actually point to.
The standard is most often invoked because ISO 3834 requires competent coordination personnel as part of its own personnel clause; this standard supplies the content of that requirement. It sits next to, not on top of, welder qualification: an ISO 9606-1 certificate qualifies the person making the weld, while a welding coordinator’s job is to make sure the right qualified welder, procedure and equipment were matched to the job in the first place — a supervisory function a diploma alone does not evidence, which is why the standard treats a relevant qualification as supporting evidence rather than automatic authorisation.
Coordination can be a single person or a distributed team, and the distributed case is where responsibility gaps hide: a task assigned to “the team” with no individual owner is, in practice, assigned to no one. A full account of the role and the audit evidence it needs walks through building that responsibility matrix. Therness equipment supports the coordination function on the production side of that matrix: continuous per-weld records a coordinator can sample against the declared scope, rather than a claim of oversight with nothing behind it to check.
| Question | If yes | If no |
|---|---|---|
| Does ISO 3834, an application standard or a contract require welding coordination personnel? | ISO 14731 sets the tasks and responsibilities to assign and evidence. | Check the specific scheme in force — most fusion-welding quality systems still expect it in practice. |
| Is the coordination task distributed across more than one person? | Each task still needs a named owner, a final decision authority and documented deputy cover. | A single coordinator has to cover the full task list the standard sets for the declared scope. |
| Does the appointed person hold a relevant diploma such as IWE, IWT or IWS? | That supports the competence evidence, but appointment still has to match the actual products, processes, materials and authority of the role. | Other documented experience and training can support the appointment; the diploma alone was never the whole test. |
| Has competence been reviewed since the last change in scope — new process, material, site or a prolonged gap in relevant work? | The appointment stands on current evidence. | A review is due before the appointment can be relied on at audit. |
Conformity is decided by inspection and testing against the criteria the standard and the contract set. The records below are evidence that the process was held where it was qualified; they support an inspection result, they never replace one.
| Requirement | Record produced | Source |
|---|---|---|
| A production record a coordinator can actually review, not only a signed appointment letter | Per-weld thermal and parameter evidence exported by job, welder and date | HeatCore AI |
| Traceability linking each weld to the procedure, welder and equipment the coordination scope covers | Weld identifier joined to WPS reference, welder ID and process record | WeldTrace |
Therness records what the machine actually delivered on every weld — parameters, thermal signature and a per-weld trail — so a conformity argument rests on measurements instead of recollection.
