provides the mandatory requirements for visual examination (VT) of welds, base materials, and components during fabrication, installation, and in-service inspection. As a foundational Non-Destructive Examination (NDE) method, visual inspection is often the first line of defense in ensuring structural integrity, detecting surface anomalies, and complying with stringent safety codes.

ASME Section V Article 9 is the cornerstone document for visual examination in the ASME Boiler and Pressure Vessel Code framework. It provides the of visual testing: written procedure requirements, personnel qualifications, physical requirements, examination techniques, lighting specifications, and equipment standards.

After implementing this latest edition, visual examination procedures must now include detailed surface preparation requirements before performing visual inspection. This simple step ensures more accurate and reliable inspection reports.

Executing an inspection to this standard requires strict adherence to three operational pillars: a formal written procedure, verified technician vision, and mandatory surface preparation. 1. Written Procedure Requirements Lighting Intensity The sequence of the examination (e
