Radiographic Metal Testing
How we prove your products meet standards?
We start by understanding your quality standards. We comply with ASTM standards and we are NADCAP accredited for Flourescent Penetrant, Magnetic Particle and Radiography Film. The standards that your parts need to meet will determine the process that we use. Below are the processess that we specialize in perfoming.
Radiographic or X-ray
non-destructive Testing for when you need to see inside the parts.
American Metal Testing, Inc. uses Radiographic Testing (RT), or industrial radiography, as a nondestructive testing (NDT) method of inspecting materials for hidden flaws in your parts.
In Radiography Testing the test-part is placed between the radiation source and film (or detector). The material density and thickness differences of the test-part will reduce the penetrating radiation through interaction processes involving scattering and/or absorption. The differences in absorption are then recorded on film place under the parts.
X-Ray inspection uses the ability of short wavelength electromagnetic radiation (high energy photons) to penetrate various materials both ferrous and non-ferrous. We use an X-ray machine as a source of photons. Since the amount of radiation emerging from the opposite side of the material can be detected and measured, variations in this amount (or intensity) of radiation are used to determine thickness or composition of material. Penetrating radiations are those restricted to that part of the electromagnetic spectrum of wavelength less than about 10 nanometers.
Radiographic applications fall into two distinct categories evaluation of material properties and evaluation of manufacturing and assembly properties. Material property evaluation includes the determination of composition, density, uniformity, and cell or particle size. Manufacturing and assembly property evaluation is normally concerned with dimensions, flaws (voids, inclusions, and cracks), bond integrity (welds, brazes, etc.), and verification of proper assembly of component pieces.
• Detects both surface and subsurface defects
• Verifys internal flaws on complex structures
• Can inspect finished components
• Minimum surface preparation required
• Provides a permanent record of the inspection
Radiographic of X-ray testing is widely used in the;
• Aerospace industries
• Manufacturing of castings and machinings
• Military defense
• Offshore industries
• Marine industries
• Power-gen industries
• Petrochemical industries
• Automotive industries
• Transportation industries
and any industry that requires better quality assurance.
