Frequently asked

Everything you ask before hiring.

Does Sparks have ISO 9606 welders available across all of Spain?

Yes. Sparks Service keeps a permanent base of ISO 9606 certified welders (processes 111, 135/136, 141 and 114) and AWS, ready to deploy within 48 hours to projects in all Spain.

How does hiring work? Do you come to my site or do I employ the crew?

We work on deployment: we send the crew to your site. We handle the local contract, PPE, lodging and transport. You only manage the technical scope of the service.

What is the minimum lead time to deploy a crew?

48 hours for projects in mainland Spain. For urgent projects (unplanned shutdowns) we try to deploy within 24 hours, subject to availability.

Do welders have verifiable qualification documentation?

Yes. Each professional comes with a valid ISO 9606 certificate, applicable WPS/PQR and an accredited certifying body. We deliver a full dossier to the client before deployment.

Do you work with planned shutdowns at refineries and petrochemicals?

Yes. We have strong experience in planned shutdowns at Tarragona, Algeciras, Huelva, Cartagena and Bilbao. We deploy dedicated crews (6G welders, pipefitters, boilermakers, supervisors) with contractual SLAs.

Which industries do you serve besides petrochemicals?

Naval (Navantia and Cantabrian shipyards), automotive (SEAT, Stellantis, Ford), aerospace (Airbus), steelmaking (ArcelorMittal), data centers and industrial construction in general.
