If you weld with a qualification in force, Spain has work for you. Refining, petrochemical and energy shutdowns chain windows throughout the year, and plants compete for the same profiles in the same weeks. The Iron Pulse pool mobilizes welders, pipefitters and boilermakers to shutdowns all over Spain — and this guide tells you, professional to professional, what we look for, which papers you need and what a real mobilization looks like. If you would rather get straight to it: apply here.
Which profiles the pool looks for
- UNE-EN ISO 9606 welders — 141 (TIG) and 111 (stick) top the demand; 6G on pipe is the most contested profile; 135/136 (MAG) adds value for structure and boiler work.
- Pipefitters — isometric reading, fit-up and spool alignment.
- Boilermakers — plate, tanks and structure.
- Fitters and maintenance mechanics — flanges, exchangers, controlled torquing.
- Supervisors — with real shutdown experience and the ability to coordinate fronts.
You do not need to tick every box: a live qualification in a couple of processes, papers up to date and availability to travel already open the door.
The paperwork you will be asked for
- A UNE-EN ISO 9606 qualification in force, with the six-monthly confirmations signed — without them the certificate lapses, even if the exam date looks recent. If you are not sure exactly what your designation covers, read it field by field with our ISO 9606 guide.
- A valid occupational medical check for the role.
- PRL training under the metal-sector agreement, plus the working-at-heights and confined-space modules the site requires.
- Identity and the right to work — if you are an EU citizen, free movement lets you work in Spain without a visa; if you come from outside the EU, you need your work authorization in order before anything else.
- A provable track record — previous certificates, sites, plants and, if you have them, radiography records: a clean history is worth gold.
How the mobilization works
When a shutdown matching your profile comes in, the call arrives with little margin: mobilizations typically close within 48-72 hours. That is why the dossier is validated beforehand, not at the gate: with your documentation already uploaded and reviewed, what remains is organizing travel and lodging — which are on the company —, handing you the PPE and passing the plant safety induction on day one. Some clients also require an entry weld test: it is normal, so prepare it for what it is, a short exam. From there, intense weeks of concentrated shifts, and rest until the next window.
What the pay looks like
Pay depends on the applicable provincial agreement, the profile and the project, and in a shutdown the stacked hours fatten the paycheck considerably; lodging and travel usually come on top, covered by the company. To calibrate your market value, it helps to know what plants pay for a homologated welder: we break it down in how much an ISO 9606 welder costs in Spain — written for buyers, but it works as your mirror. And one rule that never fails: a written contract and Social Security registration before you start; whoever does not offer you both is not offering you work, they are offering you a problem.
Keep your qualification alive
- Confirmations every 6 months — signed by your employer or welding coordinator; keep them with no gaps.
- Revalidation on time — depending on the route of your certificate, with a new test or with tested production welds; note the date before an inspector reminds you of it.
- Work within your range — and if you are going to change process or material, get examined before the job demands it.
- Copies and numbers — always carry copies of your certificates and their issue numbers: verification with the issuing body is increasingly common.
Tips to stand out in the pool
6G and a second process multiply your calls. The repair rate is tracked on every shutdown: clean radiography brings you the next mobilization without asking. Availability — answering fast and being able to leave within 48 hours — decides many tied assignments. And supervisors call back whoever adds up on site: punctuality, safety and zero drama weigh as much as the bead.
Life on a shutdown: what to expect
A shutdown is nothing like a workshop. You work in shifts, often at night, with work permits opened and closed every day, inspection on top of every joint and hundreds of external workers sharing the plant. The pace is demanding, but the treatment is professional: proper PPE, clear procedures and non-negotiable safety — in a classified zone, a lapse is not up for discussion. Whoever arrives on time, respects the permits and welds within their range finishes the window with a fattened paycheck and a phone ringing for the next one. Many professionals in the pool chain several shutdowns a year and organize the rest of their calendar around them. And between windows, training — an ATEX module, a new process — is the best investment: every extra line in your dossier means more calls.
How to apply
Send your CV from the work with us page with the full designations of your certificates (not just "I have the 6G": process, material, thicknesses, positions), the plants and sites where you have worked and your availability to travel. We validate your documentation, you enter the pool and, when a compatible shutdown comes up, we call you. Windows do not wait — neither should your application.
