Welding Certification for Europe: EN ISO 9606-1
8 min read · updated August 2026
Why welding is worth the trouble
Across our salary data, a certified welder is the largest single step available from an unskilled start. The Czech median for a welder is €1,484 net a month against €1,134 for an order picker — roughly a third more, and the gap widens with experience because a certified welder is far harder for an employer to replace.
It is also the one route where retraining genuinely works. Several placements start on a production line and qualify while working. It takes months rather than weeks and it is the difference between a contract and a trade.
What the certificate actually qualifies you for
The most common misunderstanding is that you become 'a certified welder'. You do not. EN ISO 9606-1 qualifies you for a specific combination, and outside that combination the certificate does not speak for you:
| Variable | What it means |
|---|---|
| Welding process | MIG/MAG, TIG, manual metal arc and so on. Each is separate. A plant hiring TIG welders will not accept a stick certificate. |
| Filler material group | Groups FM1 to FM6, covering material families from unalloyed steels through to nickel alloys. |
| Product type and joint | Plate or pipe; butt weld or fillet weld. |
| Thickness range | For butt welds, roughly from the tested thickness downward to a minimum and up to twice the tested thickness. Fillet welds qualify by base-material thickness. |
| Position | Per ISO 6947 — PA, PB, PC, PD, PE, PF, PG for plates, plus PH and PJ for pipes. Testing in a harder position generally also qualifies the easier ones. |
The practical consequence when you read a vacancy: 'welder' in the title tells you almost nothing. The process and the position in the body of the advert tell you whether you can actually take the job.
Keeping it alive
Two clocks run at once, and the shorter one is the one people miss.
Every six months, the qualification must be confirmed by the responsible welding supervisor or the certification body. Without that confirmation the certificate becomes invalid. It is an administrative step rather than a re-test, and it lapses quietly.
Every three years, full renewal is required — either by re-testing, or by documentary evidence every two years that at least two production welds passed radiographic, ultrasonic or destructive testing.
If you are moving between employers, the six-month confirmation is a question worth asking: who is the responsible welding supervisor at the new site, and will they confirm your existing qualification.
Who issues it in Czechia, and what it costs
Only accredited personnel certification bodies operating to ČSN EN ISO/IEC 17024 may issue ISO 9606-1 welder qualifications in the Czech Republic. STAVCERT is one published example; CWS ANB is the national welding society route.
Indicative fees from one provider's published list — a renewal test taking around three days, certificate issuance at 1,200 Kč, a new qualification certificate at 900 Kč, additional certificates in the same method at 2,500 Kč each, including VAT. These are one provider's prices, not a national tariff. Treat them as an order of magnitude.
What we could not verify, and are therefore not claiming
The question every welder actually asks is whether a certificate from India, Nepal, Pakistan or the Philippines is accepted in Europe as it stands. We looked and could not find a citable answer, so we are not giving you one.
What we can say is what follows from the structure. ISO 9606-1 qualifications in Czechia may only be issued by accredited bodies operating to ISO/IEC 17024. A certificate not issued to that standard by an equivalent accredited body is therefore unlikely to be usable directly — but that is an inference from the accreditation rules, not a sourced statement about recognition practice.
The honest advice: assume you will be tested in Europe, budget the time for it, and treat your existing certificate as evidence of skill rather than as a credential that transfers. If you want certainty for your specific certificate, ask a Czech certification body directly — they will tell you in one email, and it is a better source than any website including this one.
We previously stated on our welding vacancies page that home-country certificates 'will usually not be accepted'. That was firmer than our evidence supports and has been softened to match what we can actually show.
If you are starting from nothing
The realistic sequence, and it is slower than the marketing version:
- Enter on an unskilled role at a plant that does its own welding. The employer catalogue on this site shows which ones do.
- Establish yourself — six months minimum before you can change employer anyway, and a supervisor who knows your work is worth more than a certificate from a stranger.
- Train and test for a specific process and position that the plant actually needs. Ask which one before you choose.
- Add qualifications one at a time. Additional certificates in the same method are the cheapest ones you will ever buy.

Frequently asked questions
Will my welding certificate from India be accepted in Europe?
We could not find a citable answer and are not going to invent one. Structurally, ISO 9606-1 qualifications in Czechia may only be issued by accredited bodies, so a certificate issued outside that framework is unlikely to transfer directly. Assume re-testing, and ask a Czech certification body about your specific certificate.
What does an ISO 9606-1 certificate cover?
A specific combination of welding process, filler material group, product type, thickness range and position — not welding in general. Outside that combination it does not qualify you.
How long is it valid?
It must be confirmed every six months by the responsible welding supervisor or certification body, and fully renewed every three years by re-testing or by documented production-weld testing.
How much does certification cost in Czechia?
One provider publishes certificate issuance at 1,200 Kč and additional certificates in the same method at 2,500 Kč, with a renewal test taking around three days. That is one provider's list, not a national tariff.
Can I train as a welder while working in Czechia?
Yes, and it is the realistic path. Enter on an unskilled role at a plant that welds, establish yourself, then qualify for the process and position that plant actually needs. Months rather than weeks, and roughly a third more pay at the median.
Which process should I certify in?
The one your employer needs, which is why asking before you choose matters. MIG/MAG, TIG and manual metal arc are separate qualifications and a certificate in one says nothing about the others.
