VISUAL TESTING

RRL NDT offers visual testing and inspection services, as well as training.

Visual Testing & Inspection

All methods of nondestructive testing (NDT) at some point fall back on the most basic of inspection techniques — visual testing (VT). Whether performing a liquid penetrant test, magnetic particle test, reviewing radiographs of welds, observing an ultrasonic instrument’s scope, or evaluating eddy current signals, visual examination eventually comes into play in all methods of nondestructive testing. Although visual testing may seem simple, it is important to have your visual testing performed by a certified technician who has proper training.

Some of the issues that visual testing can be used to detect include cracks on the surface of materials, poorly aligned or missing parts, defects in welds, corrosion, and more flaws that are readily visible.

Visible testing can be performed with the help of other tools, though it isn’t required. These tools will vary based on the job and may include tools such as remote viewing equipment, machine vision, fiber optics, video presentation systems, optical prisms, magnetic film, and more. These tools are used to aid the perspective of the technician, reach places that are not normally visible, and help examine the part or system more closely.

Some of the advantages of visual testing are that it often doesn’t require any specialized equipment, just a trained technician. Visual testing is great for identifying large issues. However, visual testing has many limitations; it cannot identify defects that are not visible to the human eye or issues underneath the surface. Visual testing pairs well with other types of nondestructive testing.

If you need visual testing, RRL NDT’s trained level II and level III NDT technicians can help. Our technicians can travel to your site or facility in order to provide the testing you need, which isn’t just limited to visual testing! We also provide visual testing training and training in other types of nondestructive testing. Depending on your needs, training can be performed at our facility in Georgia or your business location.
