"How much does a UNE-EN ISO 9606 welder cost?" is the question we hear most. The honest answer: it depends, and the spread reaches 3× by process, position and project type. These are the real bands in Spain for 2026.
Hourly bands (client-facing rate)
- 135/136 (MAG) welder on structure: 18 €/h - 26 €/h.
- 111 (stick) welder on medium-pressure piping: 22 €/h - 32 €/h.
- 141 (TIG) welder on stainless for food/pharma: 28 €/h - 42 €/h.
- 6G welder (high pressure, petrochemicals): 38 €/h - 55 €/h.
- Welder + VT level 2 inspector (ISO 9712): 55 €/h - 80 €/h.
What sits behind the spread
- Scarcity: high-quality stainless TIG is a rare profile.
- Risk: a 6G joint at a refinery can stop the plant — the client pays for zero defect.
- Paperwork: the full dossier (certificate + WPS + WPQR) eats admin hours.
- Mobilization: moving to site —Cartagena, Tarragona, Huelva— adds transport and lodging.
Hour, day or project
Shutdowns bill by the day (10 effective hours). Continuous work bills hourly. Large installations close on a project price with productivity clauses (minimum joints/day).
The cost you do not see: rework
A welder 30% cheaper without a valid homologation costs at least 2× more: the joint is rejected on inspection and must be redone. We have seen sites halt for a week over a single failed batch.
How to ask for a quote that adds up
Spell out: process (111/135/141…), thickness, material, position, joint count and deadline. The sharper the scope, the tighter the price. Request an Iron Pulse quote at /contato.
