ACorWeld — Maciej Kochel
Independent inspection for steel structures — from the first weld to the final coat.
Welding & Coating Inspector · International Welding Engineer · FROSIO Level III · QA/QC · NDT Level 2
Most projects treat welding and corrosion protection as two separate disciplines, checked at two different stages — exactly where non-conformities slip through and claims start later. I cover both, so your structure is checked as one continuous quality story.
About
I'm a welding and coating inspector with over a decade in structural steel — from military engineering vehicles and rail rolling stock to offshore wind foundations. I started in design and process engineering, moved through welding coordination and quality-system building for industrial fabricators, and progressed to Principal Welding Engineer roles managing multiple branches and dozens of welders.
Today I work client-side as a Primary Steel Welding Engineer on one of the North Sea's major offshore wind projects, while building a parallel specialisation in corrosion protection and coating inspection — so I can follow a structure's full quality story, not just half of it.
There's no room for "it'll probably be fine" in industrial quality control. My approach is simple: no compromises. I hold welding and corrosion-protection work to the same standard, so the structures I sign off on are safe, standards-compliant, and built to outlast their design life.
What that combination means for you:
- One point of contact, not two handovers — the same person who checks your welds also checks the surface prep and coating that protects them.
- Client-side experience — I know what a project owner needs to see in a report, not just what a fabricator wants to hear.
- Systems, not just sign-offs — I've built ISO 3834 / EN 1090 certification programmes from scratch, not only audited existing ones, through to successful TÜV audits.

He handled site welding activities with a strong focus on quality, compliance, and practical execution. His disciplined approach, attention to detail, and commitment to delivering proper results under challenging site conditions were highly appreciated."
"I had the pleasure of working closely with Maciej Kochel at HD, where he played a key role in developing and implementing our welding standards. Maciej's deep technical knowledge, structured approach, and dedication to quality were instrumental in elevating our welding procedures to a new level."
"I had the pleasure of working with Mr. Maciej on welding technology qualification, and I can wholeheartedly recommend him as a professional in this field. His technical knowledge, familiarity with standards, and hands-on welding experience mean every project runs smoothly and in line with requirements."
"I had the opportunity to co-operate with Maciej when certifying welders and qualifying welding procedures at Mostostal Zabrze. As a welding engineer, I could always count on solidly prepared welding documentation and proper supervision of welding works carried out in the workshop."
"Great cooperation on the Orca and Mammoth projects, where I represented Climeworks and Maciej coordinated the welding work as lead welding engineer on behalf of the subcontractor, HD. Recommended!"
Let's talk about your project
