Welding is one of the most critical processes in industrial construction and manufacturing. The quality of welded joints directly affects the strength, durability, and safety of structures such as pipelines, pressure vessels, boilers, storage tanks, refineries, and power plants. Undetected welding defects may result in structural failures, costly downtime, and severe safety hazards. To mitigate these risks, Servelo Inspection Company Ltd. delivers world-class Non-Destructive Testing (NDT), Welding QA/QC, and Certification Services. Our solutions are designed to detect flaws, qualify welders, validate procedures, and ensure compliance with the strictest international welding standards.
Scope of Services
Non-Destructive Testing (NDT) of Welds
We apply advanced NDT methods to detect surface and subsurface defects without damaging the welded component:
• Ultrasonic Testing (UT): Detects internal flaws such as cracks, porosity, and lack of fusion.
• Radiographic Testing (RT): Uses X-ray/Gamma radiation to identify internal discontinuities.
• Magnetic Particle Testing (MT): Locates surface and near-surface cracks in ferromagnetic materials.
• Dye Penetrant Testing (PT): Detects open-to-surface cracks, porosity, and weld defects.
• Visual Testing (VT): First-line inspection to identify surface flaws, dimensions, and weld finish.
All NDT procedures are carried out by certified Level II/III inspectors (ASNT/PCN/ISO 9712) to ensure accuracy and reliability.
Welding Inspection & Defect Analysis
• Identification and classification of weld discontinuities.
• Evaluation of weld quality against applicable codes (ASME, AWS, API).
• Recommendations for repair and corrective measures.
Welder Qualification & Procedure Qualification
• Welder Qualification Tests (WQT): Evaluation of welders’ skill and competency.
• Welding Procedure Specification (WPS) & Procedure Qualification Record (PQR): Preparation and qualification in compliance with ASME Section IX, AWS D1.1, and ISO standards.
• Ensures consistency and repeatability in welding processes.
QA/QC Inspection for Projects
• QA/QC services for fabrication, erection, construction, and shutdown projects.
• Monitoring of welding processes, joint fit-ups, consumable control, and post-weld heat treatment (PWHT).
• Inspection of pressure equipment, pipelines, and structural welds.
• Assurance of code compliance and quality control throughout the project lifecycle.
Material Verification & PMI (Positive Material Identification)
• On-site PMI testing to confirm material grade and composition.
• Prevents mismatches and ensures correct materials are used for fabrication and repairs.
Documentation & Certification
• Complete reporting and certification packages for every inspection activity.
• Compliance with ASME, AWS, API, ISO, and other international codes.
• Audit-ready documentation for clients, third-party inspectors, and regulatory authorities.
