Course Description

*** Over 1300 Students Enrolled and Counting ***

Take a listen to what people are saying about my course:

This is my first course with Mustapha on Udemy, I think that the contents prepares the student to understand the scientific and technical details of the ultrasound topic in a more easy way than any other course. He goes to the point and that's an important characteristic for me in the industrial knowlede. Thank you for give us this opportunity to learn about this topic. We waiting for UT level II with Mustapha. Jesus Legarda

Ultrasonic testing (UT) is a family of non-destructive testing techniques based on the propagation ofultrasonic waves in the object or material tested. In most common UT applications, very short ultrasonic pulse-waves with center frequencies ranging from 0.1-15 MHz, and occasionally up to 50 MHz, are transmitted into materials to detect internal flaws or to characterize materials. A common example isultrasonic thickness measurement, which tests the thickness of the test object, for example, to monitor pipework corrosion.

The field of Nondestructive Testing (NDT) is a very broad, that plays a critical role in assuring that structural components and systems perform their function in a reliable and cost effective fashion. NDT technicians and engineers define and implement tests that locate and characterize material conditions and flaws that might otherwise cause serious accidents such as, planes to crash, reactors to fail, trains to derail, pipelines to burst, and a variety of troubling events.

These tests are performed in a manner that does not affect the future usefulness of the object or material. In other words, NDT allows parts and materials to be inspected and evaluated without damaging them. Because it allows inspection without interfering with a product's final use, NDT provides an excellent balance between quality control and cost-effectiveness.

The need for competent personnel to perform NDT tasks is paramount in all industries. In order to determine competency, systems have been devised to ensure that NDT personnel have the proper training, have passed written and practical examinations, and have enough experience to properly perform NDT tasks using the applicable test method or technique. Personnel that have met all three of these requirements are said to be “qualified,” and once qualified they can be certified, which is defined in several different ways under the various NDT systems.

Section 2: Non Destructive Testing: An Overview

Diffraction refers to various phenomena which occur when a wave encounters an obstacle or a slit. In classical physics, the diffraction phenomenon is described as the interference of waves according to the Huygens Fresnel principle.

In this lecture you will see simulations of the diffration, which will make you able to understand what happen when a sound wave diffract at an interface between two different materials.

01:40

In air, sound travels by the compression and rarefaction of air molecules in the direction of travel. However, in solids, molecules can support vibrations in other directions, hence, a number of different types of sound waves are possible. Waves can be characterized in space by oscillatory patterns that are capable of maintaining their shape and propagating in a stable manner. The propagation of waves is often described in terms of what are called “wave modes.”

It is convenient to define the beam 'edge' as the point, across the beam, where the intensity of sound has fallen to one half, or sometimes one tenth of the intensity at the center of the beam.

In this lecture you will learn how the energy of sound varies within the test specimen.

03:31

The frequency and the diameter of the probe have direct effects on the sound beam. In this lecture you will know what are these effects.

Section 7: Angular Incidence
01:06

What is the reflection and how it occurs?

If an acoustic wave meets an interface of two materials with different impedances (impedance mismatch) a part of the energy is reflected while the other part is transmitted. You will see detailed description of this phenomena within this lecture.

Refraction is the change in direction of propagation of a wave due to a change in its transmission medium. The phenomenon is explained by the conservation of energy and conservation of momentum. Due to change of medium, the phase velocity of the wave is changed but its frequency remains constant.

More informations about this phenomena is included in this lecture.


01:01

Another important phenomenon is mode conversion that is a generation of one type of wave from another type in refraction. Here you will see a simulation showing how the mode conersion occurs.

02:32

If you want a probe to generate a shear wave within the material being inspected we should calculate the incident angle ( the angle at which we must cut the perspex wedge). To do so a relationship between the incident and refracted angles is given by Snell's law.

TOFD is a high performance nultrasonic testing technique which offers the accurate detection of cracks, slag and lack of fusion. It is an improved version of the conventional ultrasonic testing method which provides a fully computerized system able to scan, store, and evaluate indicators in terms of height, length, and position. There is no other method currently available with similar grade of coverage, precision and speed.

Here is a presentation of ToFD, how it is carryed out and its advantages and limitations.

02:47

An angled sound path allows the sound beam to come in from the side, thereby improving detectability of flaws in and around welded areas. Angle Beam Transducers and wedges are typically used to introduce a refracted shear wave into the test material. The geometry of the sample below allows the sound beam to be reflected from the back wall to improve detectability of flaws in and around welded areas.

You will learn the prupose of this technique and the basic calculations that you may need to do when performing it.

01:50

Another way to couple the sound from transducer to a test object is coupling the sound with water. This can be done with squirters where the sound travels through a jet of water or by immersing the transducer and test object in a tank of water. Both techniques are called immersion testing. In immersion testing , the transducer is placed in the water, above the test object, and a beam of sound is projected.

An overview of this technique and its advantages and limitations is given in this lecture.

Section 10: Ultrasonic Reference Blocks
Article

Angle beam calibration requires use of an appropriate test block that provides two sound paths of known length. Commonly this will be an ASTM E-164 or IIW-type block, although other standards like AWS DSC blocks can also be used. The general procedure description in lecture 33 assumes use of an IIW Type 1 calibration block or equivalent.

What is the IIW block ? and its dimensions? this lecture gives the answers.

Article

For the miniature angle-beam probe one uses the considerably smaller and lighter Standard Calibration Block 2 (V2 block). This has, as opposed to the V1 block, two circle segments with a common center point, however it does not have saw cuts.

Experimentations conclude that V2 blocks in calibrated dimensions are in agreement with the technical specifications of EN 27963 standard.

In this lecture you will know the dimensions and charactestics of this block.

1 page

In this lecture we will present the Area Amplitude blocks.

This type of blocks is a set of eight flat-bottom hole blocks used to determine the relationship between flaw size and echo amplitude by comparing signal responses. Metal travel distance is 3.000” for all blocks, and FBH diameter ranges from #1 (1/64") to #8 (8/64"). In accordance with ASTM E127 (for 7075-T6 aluminum only).

1 page

In this lecture we will see the Distance Amplitude Blocks.

Distance Amplitude Blocks come in a set of 19 ASTM E 127 (7075 Alum) or ASTM E 428 (all other materials) Distance Amplitude Set. All Flat Bottom Holes are the same . This set is used to determine the relationship between metal distance and signal amplitude by comparing signal responses obtained.

Go through the lecture to know more

09:07

The location of a discontinuity can be instantly determined using its echo if the instrument is correctly calibrated. Calibration means, linear display, from the zero point on the scale, of a certain distance range of the object to be tested. The zero point on the scale corresponds to the surface of the test object and the 10th scale graduation the maximum distance, e.g. 100 mm steel, 10 mm aluminum, 25 mm brass etc.

In this lecture you will learn the basic method for the calibration of different characteristics of the system.

Section 11: Inspected Part Variations
02:57

An important variable is that of surface condition. The differences in surface finish can result in large variations in the results of an examination.

The roughness of the surface affects the test results. in this lecture you will learn these effects.

Article

Surface coatings are added to protect the surface from different effects. They can attenuate the sound wave or affect the coupling conditions. In this lecture you will learn wmore abou the surface coatings and how can they affect the test results.

02:04

To accurately predict the effects of curved surfaces on pulse/echo immersion inspection, it is necessary to have a set of models for the transducer radiation field, the flaw response signal, and the microstructure induced noise.

In this lecture you learn how the surface curvature affect the results and what are the solutions to avoid these effects.

02:06

The grain size has a direct effect on the scattering which affect the amount of energy attenuated withing the material being inspected.

Depending on the grain size, three scattering types were defined by the scientists.

In this lecture you will learn the link between the scattering types and the grain size.

Section 12: Discontinuity Variations
03:38

Discontinuities are interruptions in the typical structure of a material. These interruptions may occur in the base metal, weld material or "heat affected" zones. Discontinuities, which do not meet the requirements of the codes or specification used to invoke and control an inspection, are referred to as defects.

This lecture will give you a list of all the defect shapes that you can detect while performing an ultrasonic test.

08:26

In ultrasonic evaluation one is frequently able to come near to the true reflector size as long as the discontinuity is large compared to the diameter of the sound field.

There are many methods to find out the dimensions of a discontinuity. This lecture will give you the fundamentals of the sizing of the flaws.
