Non Destructive Testing

The goal of this project is to study and apply the different non destructive testing techniques to different components and pieces to analyze their structure and verify their quality for service performance. The methods used in this project are particle inspection, liquid penetrant inspection, ultrasonic inspection, inductive currents and X-Ray inspection.

Liquid Penetrant Inspection

This type of inspection is based on the capacity of some liquids to infiltrate inside damaged materials through its surface revealing the existance of these defects.

Both red and fluorescent marks reveal inner fissures inside the components that can't be present if these pieces are intended to be in service. This way it's possible to inspect components without damaging them

Magnetic Particle Inspection

This process aims to reveal surface discontinuities in ferromagnetic materials. This is accomplished by applying a longitudinal or circular magnetic field combined with the addition of ferromagnetic particles (solid or liquid) that get attached to the surface revealing any surface defect or fissure.

Ultrasonic Inspection

Liquid penetrant and ferromagnetic particles are used to reveal surface damage. Ultrasonic inspection aims to detect inner defects that can be revealed from the surface.

The equipment for this method is a digital ultrasonic generator with a 10 mm single crystal sensor. By the ultrasonic emission through the component the sensor will detect the wave behaviour inside of the piece abalysing if there are any discontinuities inside.

Inductive Currents

Also called, Edyy currents, this method is not only used for damage inspection but also for analysing nature and material properties as well as thickness and quality of a specific component.

This method, since it will be using inductive currents, will only work for conductor materials.
