NDT, WELDING & COATING INSPECTION
Certified welding surveillance, non-destructive testing verification, and protective coating inspection — executed strictly within verified qualifications.
- Welding
- UT/RT/MT/PT
- Coating
- Per Verified Scope

Weld integrity and corrosion protection determine the service life of critical industrial assets. QTEK provides qualified welding, NDT, and coating inspectors to oversee fabrication before, during, and after welding — ensuring full compliance with approved procedures and international acceptance criteria. All assignments are performed strictly per verified QTEK and inspector qualifications, with zero assumptions.
What QTEK verifies on every assignment
- 01Pre-Welding: Review of WPS, PQR/WPQR, welder qualification certificates, weld maps, and consumable storage / baking controls
- 02During Welding: Fit-up, bevel geometry, root gap, preheat temperature, interpass temperature, shielding gas, and heat input monitoring
- 03Post-Welding & PWHT: Visual weld inspection, Post-Weld Heat Treatment (PWHT) chart review, hardness testing, and ferrite measurement
- 04NDT Witnessing & Review: On-site witnessing of Non-Destructive Testing and independent review of RT films and NDT reports
- 05Coating & Painting Inspection: Blast profile (roughness/cleanliness), ambient conditions (dew point/humidity), WFT/DFT, adhesion pull-off, and holiday/pinhole detection
