2026 Inspection Trend ViewTech Borescopes

For decades, the primary tools of the AWS Certified Welding Inspector (CWI) were simple: a flashlight, a mirror, a fillet gauge, and a keen pair of eyes. But as engineering designs become more complex and tolerances tighten, the areas that require nondestructive examination (NDE) are becoming increasingly difficult to access.

Enter the industrial video borescope, a remote visual inspection (RVI) tool packed with adjustable lighting, photography, videography, annotation, and often measurement capabilities that elevate welding inspections to new heights. However, possessing the tool is only half the task. A borescope is not simply a camera on a wire; it is a sophisticated optical instrument that requires a few simple techniques and care guidelines to yield accurate results.

This article explores best practices for leveraging borescope technology to identify discontinuities such as porosity, incomplete penetration, and burn-through, ensuring that what we see on the screen accurately reflects the weld’s quality.

Beyond the inspection, we will also explore the often overlooked post-inspection phase and cover proper reporting techniques. Finally, we will demystify the purchasing process by breaking down exactly which features matter for welding applications, helping you make an informed decision for your specific needs.
