Alin Barbu, coating and welding inspector

Measured, recorded, signed off

I started in quality control in 2014 at The Timken Company, approving manufacturing milestones against specification and working with the metrology team on instrument calibration.

Since 2018 I have worked as an independent third-party inspector on oil and gas, petrochemical and industrial projects, alongside my role as lead quality inspector at SLB. The work covers protective coatings, welding and NDT, forgings, and source inspection of equipment before it ships.

Clients get measurements, photographs and a clear verdict against the specification, in the report format their agency or end user expects.

Precision in inspection, integrity in execution.
