This 5-10 day course provides basic knowledge into how to effectively interpret radiographs of weldments. Emphasis is placed on the radiographic image quality requirements of codes and specifications. This course is practical in nature, utilizes classroom participation, and allows for hands on application in the review of radiographic film.

• Provide classroom training hours in accordance with SNT-TC-1A and ANSI/ASNT CP-189 requirements.
• Provide hands on training with digital UT thickness measurement.
• Develop practical skills needed for practical examinations.
• Discuss and apply problems associated with digital UT thickness measurement.

This method involves both direct and indirect visual inspection techniques, direct inspection is where the material is inspected directly by the human eye with no additional visual aids, indirect inspection may involve the use of magnifying glass, mirror, boroscope (mini camera), closed-circuit TV etc.

Visual inspection is a crucial NDT method which is too often overlooked, this should be the basis for inspectors starting out in the NDT industry, for example, a visual examination of an operational plant can often reveal obvious problem areas, such as leaks, excess vibration, corrosion or misalignment, this inspection is a very cost effective exercise and can be used to identify areas that require further NDT applications.

This method involves the component under inspection being magnetized; this magnetization process is supplemented by the application of ferromagnetic particles to the already magnetized surface. The magnetic particles are attracted to areas of flux leakage (escaping magnetism) and indications formed at that point. This method is used to test welds, castings, and forgings for surface or slightly subsurface defects.

However MT can only be used to inspect materials that can be magnetized, i.e. ferromagnetic materials.

We can provide Magnetic Particle Inspection courses and examinations suitable for any of the following certification scheme.

This involves applying a liquid dye to the surface of a material and leaving the dye to “dwell” on the surface for a predetermined period of time. The liquid can be either a color that is easily visible under normal lighting conditions or a yellow/green fluorescent color that requires special lighting conditions to be seen effectively. This liquid dye enters into discontinuities that are open to the surface of the material through a phenomenon called “capillary action”. This capillary action takes place throughout the dwell time and the discontinuity retains this dye when the excess dye is cleaned from the surface. A type of developer is then

The PT method is suitable on most non absorbent materials

We can provide Liquid Penetrant Inspection courses and examinations suitable for any of the following certification scheme.

This method employs high frequency sound pulses that are emitted from a transducer; this sound wave is induced in to the material through a probe which is usually in contact with the material. These sound waves propagate through the material, and are reflected back to the probe when they reach an interface. The reflected waves are transmitted back through the probe and connecting leads to a detector which can be either analogue or digital. The sounds waves are then displayed as a series of signals on a monitor and the qualified inspector can measure, and interpret these signals to allow accurate evaluation of the internal structure of the material.

Ultrasonic testing can not only be used to indicate a surface or subsurface flaw it can also be used to determine the depth, size and type of flaw. Another advantage of using UT is the accurate measurement of the thickness of the material. The method can be applied to most materials providing the material can transmit sound waves. UT is considered to be a fast and effective way of inspection providing high sensitive results.
