Structural Repair Inspection Methodology

1. Destructive testing

To verify the integrity of a component, it is
always possible to cut or section through the
components and examine the exposed surfaces.
Components can be pulled or stressed and
pressurized until failure to determine their properties
of strength and toughness. Materials can be
chemically treated to determine their composition.
These are some forms of destructive testing.
Unfortunately this approach of destructive testing
renders the component useless for its intended use as
against non-destructive testing which can be
performed on the components and machines without
affecting their service performance.

2. Non Destructive testing

Non-destructive testing (NDT) is a
wide group of analysis techniques used in science
and technology industry to evaluate the properties of
a material, component or system without causing
damage. The terms Non-destructive examination,
Non-destructive inspection and Non-destructive
evaluation are also commonly used to describe this
technology, because NDT does not permanently
alter the component being inspected, it is a highly
valuable technique that can save both money and
time in product evaluation, troubleshooting, and
research. Common NDT methods include ultrasonic,
magnetic particle, liquid penetrate, radiography,
remote visual inspection (RVI), eddy current testing.

 Non destructive Tests:

1. Rebound Hammer Test
2. Pulse Echo Method
3. Impact Echo Method
4. Ultra Sonic Pulse Velocity Method
5. Probe Penetration Test or Windsor Probe Test
6. Ground Penetration Radar Method
7. Carbonation Test
8. Half Cell Potential Meter Test
