Visual Testing (VT) is one of the simplest NDT method. Powerful and widely used method for inspection of welds. At Trinity NDT – Centre of Welding, we provide visual inspection services for assessing weld quality. Carried out by IWE/AWS/CSWIP certified inspectors. To ensure the quality, safety, and compliance to ASME, ISO, AWS codes for welds, castings, forgings, machined parts, and critical components. With decades of experience in welding inspection and NDT services, we combine advanced tools. Skilled engineers, and internationally recognized standards to deliver inspection solutions that add real value to your projects.
Visual Inspection – First Step in Quality Control
Visual inspection is often the first step in detecting defects. During manufacturing or fabrication of welded structures, pipelines and pressure vessels. By carefully examining surfaces and welds with the naked eye, magnifiers, gauges, and digital tools, our inspectors can identify critical issues. Such as weld cracks, porosity, incomplete fusion, undercut, surface irregularities, corrosion, misalignment, and dimensional inaccuracies. Detecting such defects at an early stage helps prevent costly failures, rework, and safety hazards. While ensuring compliance with codes like ASME, AWS, ISO, and IBR.
Trinity NDT’s Visual Testing Capabilities
We go beyond basic visual testing and eye inspections. Our certified welding inspectors are trained to international standards (ASNT Level II & III, AWS CWI, CSWIP and International Welding Engineer (IWE) certified). Equipped with specialized tools to enhance accuracy and reliability in performing inspections onsite in and around Bangalore in the state of Karnataka. Also we serve pan India on need basis.
Our VT inspection kit includes:
Universal Weld gauges for measuring undercut, reinforcement, and misalignment.
Illuminated magnifiers for detailed inspections.
Digital cameras for high-resolution defect documentation.
Certified VT Level II inspectors as per ASNT and ISO9712
All inspections are carried out under controlled lighting and environmental conditions to ensure consistency. Detailed test reports are generated with photographs and measurements. We are providing full traceability for audits, certifications, and third-party reviews.
Conditions Suitable for Visual Inspection
Visual testing requires proper lighting of the weld and adjacent surfaces and clear eye-sight for the VT Level 2 inspector. To be truly
effective visual inspection does however, merit special attention because it requires training (knowledge of welding process, anticipated
service conditions, acceptance standard, documentation, for example) and it has its own range of VT equipment. It is also a fact that all
defects found by other NDT methods at the end are verified by visual inspection methods.

Borescope, Fibrescope Inspection
This Visual testing NDT method is even suitable for in-service inspection Pipes and heat exchanger tubes using borescope or fibrescope method of inspections. Aerospace engine components such as turbine blades and other difficult to access parts are tested using borescope and firbrescopes. The test results are records for future use. Development of devices for visual testing is happening at much faster pace. This make possible to use this method at many area where earliest is NOT used.
Procedure for Visual Testing of Welds
- Prepare a VT testing procedure
- Choose acceptance norms based on application of weld
- Check personnel Qualification
- Clean weld and adjacent areas
- Remove paint, rust, dust etc
- Do VT testing
- Record the image/video using camera if needed
- Complete the document (VT Test Report format Dowload)

Frequently Asked Questions on Visual Testing
What is Visual Testing in NDT?
Visual Testing (VT) is a non-destructive inspection method where trained inspectors examine the surface of materials and welds to identify visible defects such as cracks, porosity, or misalignment.
Why is VT the first step in weld inspection?
Because most defects originate on the surface, VT provides a quick and cost-effective way to detect flaws before applying advanced NDT methods.
What qualifications do Trinity NDT inspectors hold?
Our inspectors are certified as per ASNT SNT-TC-1A standards, with Level II and Level III qualifications.
Can VT detect internal defects?
No, VT identifies only surface-level defects. For internal flaws, Ultrasonic or Radiography X-ray testing, or other methods are applied.
Do you provide on-site VT inspections?
Yes, our team regularly performs visual testing at client locations across India, including factories, construction sites, and power plants.
