Welder continuity requirements: what continuity confirmation means and how to log it
Under ISO 9606-1, a welder's qualification only stays valid if their continuity is confirmed every six months by the manufacturer's welding coordinator or responsible person (clause 9.2, as summarised by TWI); this guide explains the requirement and what a continuity log must record. The hard part is rarely the date itself. It is keeping the confirmation, the evidence and the next due date in one place.

Short answer
ISO 9606-1 requires the manufacturer's welding coordinator or responsible person to confirm a welder's qualification every six months for it to stay valid. A continuity log is the dated record of each confirmation: the qualification reference, the date, who confirmed it, how, the supporting evidence and the next due date.
Who this is for
Most useful when continuity is being reviewed manually.
This guide is for businesses that already know continuity matters but need a better way to keep the record current and reviewable.
Fabrication supervisors
Teams that need to know which qualifications still have usable continuity evidence before allocating work.
Welding coordinators
People who chase confirmations, maintain due dates, and need a clearer view of gaps or overdue items.
Quality leads preparing for review
Teams that want the continuity trail ready before an auditor, customer, or internal reviewer asks for it.
Welding continuity log requirements
What a continuity log should record
A welding continuity log works when each confirmation is part of the qualification record, not a note in an email chain or a supervisor's notebook.
Keep every confirmation rather than overwriting the last one, so a reviewer can see the six-monthly trail as well as the next due date. Start from the free welder continuity log template or the welding continuity record template.
- Welder name, welder ID or stamp, and the qualification (certificate) reference being confirmed.
- The date of the confirmation and who confirmed it (the welding coordinator or responsible person).
- How continuity was confirmed, in the terms your procedure uses.
- A reference or link to the supporting evidence.
- The next due date: six months on under ISO 9606-1.
- The earlier confirmations, kept as a history.
- Continuity kept separate from the revalidation date.
Review the exact confirmation method and evidence expectations against your own procedure and certification requirements.
Spot due-soon and overdue records quickly
The app flags continuity due within 30 days and overdue. Scheduled email reminders run daily as well.
How Soteriaa logs continuity
A supervisor confirms continuity; Soteriaa keeps the log and the reminders.
Continuity in Soteriaa is confirmed by a person. It is never worked out from weld or production data.
Each confirmation records the date, who confirmed it, the method, the next due date and an evidence link. The next due date defaults to six months later (moved to the month end when that day does not exist, so 31 August becomes the end of February). Every confirmation is stored as history, entries out of date order are rejected, and the record shows the latest one. Daily email reminders go out before continuity and revalidation fall due, by default at 90, 60 and 7 days, plus an overdue reminder. See how the welder continuity tracking software works.
- Confirmed on, confirmed by, method, next due date and evidence link.
- Next due date defaults to six months later; you can change it.
- Every confirmation kept; the latest shown on the record.
- Reminder lead times configurable from 1 to 365 days, and reminders can be switched off.
Spreadsheet and folder failure points
Why continuity often slips through the cracks.
The usual problem is not a missing column. It is a missing workflow that joins the date, the evidence, and the owner together.
The next due date is easy to miss
A spreadsheet can hold the date, but it does not automatically show which confirmations are due soon, overdue, or missing evidence unless someone checks it carefully.
Evidence lives in separate folders
The record may say continuity was confirmed, but the supporting document or job trail is somewhere else and hard to retrieve under pressure.
Continuity and revalidation get mixed together
Teams often use one notes column for both, which makes the status harder to interpret and easier to misread.
Nobody owns the follow-up
A continuity date without a shared review view becomes a memory task instead of a managed record-control process.
How Soteriaa helps
Use one system for the date view, the record, and the next step.
These routes connect the continuity question to the qualification register and the related educational pages around it.
Record a single confirmation
Use the free welding continuity record template when you need one confirmation on paper.
Keep continuity beside the qualification
Track the qualification scope and the related continuity dates in one register instead of maintaining separate files.
Clarify what continuity is not
Use the companion guide to keep continuity confirmation separate from revalidation decisions and dates.
Prepare a continuity-style form
Use the free tool to preview a continuity form layout for your own record-preparation workflow.
Limitations and scope
This guide is for general record-management information only. It is not legal, certification, or standards interpretation advice.
Soteriaa helps organise continuity records, dates, and supporting links. It does not replace your own continuity procedure, approval workflow, or certification-body expectations. Review the record structure against your own procedure and certification requirements.
FAQ
Welder continuity requirement questions
These answers focus on practical record organisation. Always review your own procedure and certification requirements before changing how continuity is confirmed.
How often must welder continuity be confirmed under ISO 9606-1?
Every six months. ISO 9606-1 clause 9.2 requires the manufacturer's welding coordinator or responsible person to confirm the qualification's validity at that interval. Under ASME IX (QW-322) a qualification lapses if the welder has not used the process for six months. ISO 9606-1 is under revision, so check the edition your certificates cite.
Who signs off welder continuity?
Under ISO 9606-1 it is the manufacturer's welding coordinator or another responsible person at the manufacturer, not the examining body that issued the certificate.
Is continuity the same as revalidation?
No. Continuity is the six-monthly confirmation. Revalidation under ISO 9606-1 clause 9.3 is a separate route: a retest every 3 years, a 2-yearly check of two test welds from the last 6 months, or, under an ISO 3834-2/-3 quality system with documented production welds, validity while the welder stays with the same manufacturer (not allowed under the PED).
What evidence is usually linked to a continuity confirmation?
Teams commonly link the qualification reference, the confirmation date, who confirmed it, how it was confirmed and the document used to support it. The exact evidence should match your own procedure.
Can Soteriaa send continuity reminders by email?
Yes. Scheduled email reminders run daily for continuity due and revalidation due dates, by default 90, 60 and 7 days before (each configurable from 1 to 365 days), plus an overdue reminder. They go to the workspace alert email and can be switched off.
Does continuity confirmation prove legal compliance on its own?
No. Continuity records help organise evidence and support review, but they do not guarantee legal compliance or replace your wider quality and certification responsibilities.
