Radiography
Radiography involves the use of penetrating X- or gamma radiation
to examine parts and products for flaws that could be detrimental
to their intended use. more>>
Positive Material Identification
Positive Material Identification (PMI) involves the use of portable
units that utilize X-Ray fluorescence to determine chemical composition
of metallic objects. Alloy sorting, quality assurance checks, code requirements
more>>
Ultrasonics
Ultrasonic testing uses the transmission of high frequency sound
waves into a material to detect imperfections within the material
or changes in material properties. more>>
Liquid Penetrant
Liquid Penetrant testing is probably the most widely used NDT method.
The test object or material is first cleaned and then coated with
a visible or fluorescent dye solution. more>>
Magnetic Particle
Magnetic particle testing is done by inducing a magnetic field
in a ferro-magnetic material and dusting the surface with iron particles
(either dry or suspended in a liquid). more>>
Visual
Probably the oldest and most common method of NDT is visual examination,
which has numerous industrial and commercial applications. more>>
Acoustic Emission
When a solid material is stressed, imperfections within the material
may emit short bursts of energy called "emissions" or
“events”. more>>
Special Services
RNDT also has several special services. more>>
Common Codes and Standards
These certifications satisfy global requirements for nondestructive
testing personnel including the stringent requirements for the European
Pressure Equipment Directive. more>>
