General

Before the examination, the surface must be cleaned: coating, grease and dirt must be removed, and a special paint may be applied to make the defects more visible.

A magnetic field will be imposed which will create a leakage field at the location of a defect. On the surface, iron particles are then applied in wet or dry form. These iron particles will be attracted by the leakage field. The colour difference between the attracted iron particles and the background will mark the defect on the surface, this is called an indication. This indication is assessed by the operator using the required standard and/or specification. The surface indication shall be assessed in accordance with the required standard, resulting in acceptable or unacceptable.

Most magnetic tests are performed in daylight with the help of black ink; often in combination with a yoke. If smaller defects have to be made visible (higher sensitivity), the examination can be carried out under UV light. For a larger quantity of uniform products (such as axles, gears and bolts), the UV test is often combined with a magnetic bench. For each application, the best choice with regard to magnetising should be made in order to carry out an optimal examination.

Scope/Products/Sectors

Surface examination of ferrous materials for surface defects such as (fatigue) cracks and/or defects that are located just below the surface such as gas and slag (inclusions).

The examination can only be used for ferrous magnetic (highly magnetisable) materials, but in particular for the following products:

• Steel casting parts of more complex geometry;
• wheels, axles and rails in railway maintenance;
• Piping, accessories and/or welding of ferritic steels in the petrochemical,/offshore and/or food industry;
• High-load turbine components, such as in aircraft engines and power plants;

Training Information Level 1

For whom

The training is set up and intended for (oncoming) NDT inspectors/operators for whom a qualification and/or certification is required. The course also provides an insight into the working methods of the examination, so that the student can perform the work under the supervision of a level 2 or 3 inspector/operator.

The following components are recommended for course participants:

• A VMBO/LTS prior education or similar.
• Basic knowledge of mathematics.
• Interested in engineering.
• Technical English, to be able to read work instructions.

Structure

The training includes both a theoretical and a practical part. The training time will be divided 40/60 between the theoretical and practical part. During the training, under the supervision of experienced NDT specialists, the student will lay a foundation for future work.

The objectives

• Acquaint students with the basic principles and advantages disadvantages of magnetic testing.
• Be able to perform magnetic testing under supervision using different techniques and report the findings.
• Reading and interpreting work instructions and/or detailed procedures (mainly in English).
• Drafting of test reports (search parameters and findings).
