Certified welders on your site
MIG/MAG, TIG, MMA, SAW and FCAW welders qualified to EN ISO 9606-1, deployed to your procedures (WPS/WPQR) and your supervision — for weeks or for years.
Polish outsourcing company · welders & fabricators
We take on the projects your welders can’t reach.
IWS supplies certified welders, fitters and complete crews to steel, energy, shipbuilding and heavy-industry projects across Europe — executing your scope in an area inside your facility, under our own supervisor, to your procedures, invoiced per kilogram or tonne accepted. We do not manufacture in our own name.

Services
One partner from the first welder to the last weld map.
Fitters, hull fitters & assemblers
Steel-structure fitters, pipe fitters and hull fitters who read the drawing, set up the assembly and hand it to the welder ready to tack.
Complete project crews
Our own supervisor, welders, fitters and grinders as one unit in a rented area inside your facility — invoiced per kilogram or tonne against acceptance protocols, per hour, or per work package.
Pipework & pressure equipment
Welders and fitters for pipelines, boilers and pressure vessels — in your prefabrication shop and on your site — for refineries, power plants and petrochemical plants.
Quality & documentation
Welder qualification records, welding maps, NDT coordination and the paperwork your QA department expects with every crew.
Posting compliance (A1)
Workers posted from Poland with A1 certificates, insurance and the documents host-country inspections ask for — handled by us, not by you.
Projects
Work of this kind, delivered for names you know.
IWS supplies the certified people; the client keeps its procedures, inspection and schedule. Three programmes our crews work in today.
Transition pieces and secondary steel for offshore wind
Our client builds the transition pieces and jackets that carry offshore wind turbines, including foundations for the first Polish offshore wind farms in the Baltic. IWS welders and fitters work inside this programme to the client’s qualified procedures: heavy-plate butt and fillet welds, secondary steel, boat landings and platforms, under third-party inspection.
Crane portals, conveyors and stacker-reclaimer steel
Our client has built hoisting and bulk-handling equipment for over sixty years — portal loaders, conveyor systems and coal-handling plant for chemical works and power stations. IWS supplies welders and fitters for box girders, portal legs, conveyor bridges and machined weldments, working to the client’s WPS and its certified quality system.
Hull blocks, sections and outfitting steel
At the yard on the Baltic coast, IWS crews weld and fit hull sections and blocks — double bottoms, side shells, bulkheads and decks — plus foundations and outfitting steel, in all positions and to classification-society rules. Hull fitters, the trade every yard in Europe is short of, are a core IWS speciality.
Client programmes are described from the clients’ own public material; IWS names a client only with its written consent. Reference contacts on request.

About IWS
A Polish outsourcing company built around the welder, not the brochure.
IWS — International Welding Services — is a licensed Polish outsourcing company. We recruit, qualify and post welders and fabricators to industrial projects and execute complete welding scopes in a rented area inside the client’s plant: our workers, our supervisor, your drawings, procedures and inspection, invoiced per kilogram or tonne against acceptance protocols. We do not manufacture in our own name — the product, the certificates and the client relationship stay yours.
Our people come with their certificates, their A1 forms and a coordinator who speaks your language. Our clients keep their own procedures, their own inspection and their own schedule — and add capacity when the order book demands it.
- Welders qualified per EN ISO 9606-1, retested on your WPS on request
- Posting handled end-to-end: A1, insurance, travel, housing
- One coordinator, weekly reporting, week-notice scaling
Questions from procurement
The answers your buyer will ask for first.
How fast can a crew be on site?
A first proposal within two working days of receiving drawings, standard, processes and positions. Mobilisation of an EU-posted crew with A1 certificates typically takes two to four weeks; welders already in our pool can start sooner.
Which welding qualifications do your welders hold?
Every welder carries a valid EN ISO 9606-1 certificate for the process (111, 135/136, 141, 121, 114), material group and position you specify. On request we run a test weld to your WPS before mobilisation and send you the record.
Who is the employer, and who handles posting paperwork?
IWS is the employer. A1 certificates, insurance, travel, accommodation and PPE are organised by IWS, and the crew arrives with the documents host-country inspections ask for. You receive one invoice.
How do you price — per kilogram, per hour or per work package?
All three. Most of our scopes are invoiced per kilogram or tonne of welded steel accepted, against a signed acceptance protocol — you pay for result, not attendance. Hourly rates for personnel supply and fixed prices for defined work packages are also possible.
Can we scale the crew up or down?
Yes — with one week’s notice in either direction. One IWS coordinator stays your single point of contact for hours, progress, NDT results and replacements.
Do you manufacture anything yourselves?
No. IWS is an outsourcing company: we rent an area inside your plant, yard or site, and our welders and fitters execute your scope there under our own supervisor, to your drawings, WPS and inspection. You accept the work by protocol and we invoice by kilogram or tonne. Nothing is fabricated in IWS’s name, so your quality certificates and your client relationship stay entirely yours.
Do you work under our quality system?
Always. We weld to your qualified procedures, under your welding coordinator and your inspection, and structure our records to fit your EN ISO 3834 / EN 1090 / class system.
