“Welding Inspection You Can Trust. Quality You Can Verify”
Professional Welding Inspection Services
Independent welding inspection and QA/QC support for fabrication, piping, pressure equipment, steel structures, mechanical equipment and industrial projects.
Independent Welding Quality Verification
Welding quality is critical to the safety, integrity and reliability of fabricated equipment and structures.
More Inspection International Services (MIIS) provides professional Welding Inspection and welding QA/QC support for engineering, oil & gas, petrochemical, power, energy, fabrication and industrial projects.
Our inspection activities can cover the complete welding cycle, from review of welding documentation and material identification through fit-up, welding, visual inspection, NDT, dimensional verification, testing and final documentation.
Inspection activities are performed according to the applicable project specifications, approved procedures, drawings, ITP requirements and relevant codes and standards.
Why Welding Inspection Matters
Effective welding inspection helps identify problems early and supports consistent fabrication quality.
Weld Integrity
Verify welding activities against approved procedures, drawings and project acceptance requirements.
Quality Compliance
Monitor compliance with applicable welding procedures, qualifications, inspection requirements and specifications.
Early Defect Detection
Identify welding and fabrication issues before they progress into more expensive repairs or project delays.
Welding Inspection Scope
Our welding inspection scope can be adapted to the project ITP, specifications and fabrication requirements.

Welding Documentation Review
Welding documentation provides the foundation for controlled and traceable fabrication.
WPS
Review welding procedure requirements against the applicable project and code requirements.
PQR
Review procedure qualification records and supporting qualification information.
WQT / Welder Qualification
Verify welder qualification records and applicability to the welding work being performed.
Welding Consumables
Verify consumable identification, storage, control and applicable requirements.
Inspection & Test Plan
Establish inspection activities, hold points, witness points and required records.
Material Certificates
Review material certification and traceability requirements where applicable.
Welding Inspection Stages
Welding inspection should continue from preparation through completion rather than focusing only on the finished weld.
Before Welding
Review materials, WPS, welder qualifications, joint preparation and consumables.
During Welding
Monitor welding process, preheat, consumables, parameters and workmanship.
After Welding
Perform visual examination and verify weld profile, dimensions and surface condition.
NDT & Final Review
Witness applicable NDT, testing and review final welding documentation.
Common Welding Defects We Monitor
Inspection focuses on identifying weld conditions that may not meet the applicable acceptance criteria.
Lack of Fusion
Inadequate fusion between weld metal and base metal or between weld passes.
Lack of Penetration
Incomplete penetration at the weld root where complete penetration is required.
Porosity
Gas pockets or cavities within or adjacent to the weld metal.
Undercut
Groove or reduction of base material adjacent to the weld toe that exceeds acceptance requirements.
Cracking
Surface or internal cracking requiring assessment against applicable acceptance criteria.
Excessive Reinforcement
Weld profile or reinforcement exceeding specified dimensional requirements.
Practical Welding Quality Control
Effective welding inspection is more than checking a completed weld. It requires verification of the complete welding process and the documentation supporting it.
Our inspection approach focuses on identifying potential quality problems early, communicating findings clearly and maintaining traceability throughout fabrication.
The inspection scope is established according to the approved project documentation and applicable acceptance criteria.

- Welder qualification
- Material identification
- Joint preparation
- Fit-up and alignment
- Preheat and interpass temperature
