Welding inspections | QAQC
Our mission is to ensure that manufactured steel products meet the established quality standards, codes, and norms. We take care of welding quality assurance, process selection and welding work supervision. Our task is to prevent possible manufacturing defects, reduce waste and contribute Client to overall success.
Who we are
We are a small team of welding coordinators located in Estonia, Tallinn. We play a role in overseeing welding operations and ensuring they are carried out as per Client’s needs and requirements.
As a welding coordinators or site inspectors, we act as the “eyes and ears” of the Client, representing their interests and ensuring that welding operations are carried out in accordance with the required codes and standards.
Our inspectors obtain several certification degrees such as IWE, VT-2, PT-2, pressure vessel certification and several others.
As welding inspectors, we can handle a combination of desk and site responsibilities. By effectively managing both desk and site work, we can ensure that the product is assembled and manufactured as per Client specs and drawings.
Acting as the Client’s representative we check but not limited to the following:
That WPS/PQR are followed
Verification of welder qualification
What we do
Inspection of pipe spools with endoscope
This method is particularly useful for industries such as oil & gas, chemical manufacturing, and water treatment, where the integrity of piping is critical to safety and operational efficiency.
The images or video footage can be recorded for documentation, analysis, and reporting purposes.
Welding inspections (ad-hoc, second or third party)
Where needed, we are ready to act as 2nd and 3rd party inspectors. Second-party inspectors provide internal oversight and quality control, while third-party inspectors provide an independent and impartial assessment of the welding work.
Depending on the specific project or requirements, either or both types of inspectors may be involved to ensure that the welding work meets the necessary standards for safety, performance, and quality.
Site management
Our guys are physically fit to perform QC checks on site. Using proper EHS equipment we can perform welding inspections at height and confined areas.
NDT
Getting NDT results (protocols, photos, X-ray films) faster can be achieved through effective planning, communication, and proactive management. We do that job for the Client.
Prior to NDT application we are checking the weld log, composing a weld map with all the required data for proper NDT inspection.
Surface treatment inspection
- Surface roughness evaluation
- Blasting quality
- Pull off testing
- Dust testing
- MEK testing
- NDFT measurements
Hydrostatic testing of piping and pressure equipment
We check all gasket surfaces of flanges on the matter of mechanical damages, perform visual check of inner surface of the vessel, ensure that bolts are torqued as per spec.
Let us take care about your inspection of hydrotesting activities.
