Jun 3, 2021 · Visual testing (VT) or also called VT is a surface non-destructive inspection (NDT) method. It is simple, easy to apply, and requires the least tools for the NDT inspection. Just because it is simple and cheap- it should not be ignored or bypassed.

Feb 26, 2020 · The 5 most important types of NDT are the following, they differ in the tools used and the evaluation e.g. imaging techniques. VT – Visual Testing; MT – Magnetic Particle Testing; PT – Penetrant Testing; UT – Ultrasonic Testing; RT/DR – …

Visual testing is an NDT method that involves the direct observation of a component to detect surface discontinuities. It is the simplest and most fundamental form of NDT, often serving as a preliminary step before applying more complex methods.

Visual inspection (VT) is the original method of nondestructive testing (NDT) and is considered the most effective NDT testing technique for detecting surface defects.

Visual Testing (VT), also known as Visual Inspection, is a cornerstone of Non-Destructive Testing (NDT) and is often the first step in evaluating the integrity of a material, component, or structure.

Explore ASNT's Visual Testing (VT) courses, including certification prep and eLearning options. Deepen your expertise, earn recertification points or CEUs, and advance your nondestructive testing (NDT) career with flexible, industry-specific training.

Understand the processes and techniques by which VT is applied to the examination of materials, components, and structures. Know the importance of the qualification and certification of personnel in VT. Recognize the advantages and limitations of VT. The oldest and most commonly used NDE method is Visual Examination (VT).

Our efficient NDT services help you detect defects in base materials, products, installations and equipment. This provides asset management data which enables you to prevent damage and related cost resulting from material failure.

Liquid penetrant inspection is a widely applied and low-cost inspection method used to locate surface-breaking defects in all non-porous materials (metals, plastics, or ceramics).

Non-destructive testing (NDT) refers to information collection processes that avoid harming or permanently modifying the structure being inspected. Out of all the nondestructive testing methods, visual testing is the most popular because it’s easily done, low cost and does not require a lot of expensive equipment.
