NON-DESTRUCTIVE TESTING
X-ray Markers for Non-Destructive Testing
AC Wellman produces the finest-quality X-ray letters, numbers, arrows, and logos used in non-destructive testing (NDT). Using high-grade alloys, we manufacture lead and lead-free characters that provide perfectly-readable X-ray markings during testing. Because AC Wellman is an expert in the design and manufacturing of X-ray markers, and the markers are produced in the U.S.A., we make the best NDT letters in the industry. Quality, reliability, and service are synonymous with AC Wellman.
VARIETY | QUALITY | RELIABILITY
We produce over 350 different fonts, sizes, numbers, and arrows used for NDT. Our most common font is FLAT FACE NO.1, which is available in multiple heights, thicknesses, and widths.
Most common sizes: 1/8″ | 1/4″ | 3/8″ | 1/2″
Deep Drawn: 1/4″ | 1/2″

Common Industries that Use Non-Destructive Testing
Aerospace
Defense
Oil and Gas
Power Generation
Automotive
Biomedical
These sectors use the NDT test to determine the physical properties of materials such as impact resistance, ductility, yield, ultimate tensile strength, fracture toughness, and fatigue strength. Visual testing is the most widely used method of non-destructive testing (NDT) among others.
What Is Non-Destructive Testing?
Nondestructive testing (NDT) is the process of inspecting, testing, or evaluating materials, components or assemblies for discontinuities, or differences in characteristics without destroying the serviceability of the part or system. Many industries, including aerospace and automotive, use NDT to ensure the quality of products. These sectors use the NDT test to determine the physical properties of materials such as impact resistance, ductility, yield, ultimate tensile strength, fracture toughness, and fatigue strength. Visual testing is the most widely used method of non-destructive testing (NDT) among others.
