Magnetic Particle Testing (MT): Requirements and Learning

Magnetic Particle Testing (MT) is a non-destructive testing (NDT) method used to detect surface and near-surface flaws in ferromagnetic materials. It works by magnetising the material and then applying ferromagnetic particles, which are attracted to areas where there is a magnetic flux leakage caused by a flaw. CSWIP (Certification Scheme for Welding Inspection Personnel) and PCN (Personnel Certification in Non-Destructive Testing) are certifications that validate an individual's competency in performing MT and other non-destructive testing methods. These certifications ensure that inspectors are properly trained and qualified to carry out inspections to industry standards.

The course offered by TWI Training caters to a broad spectrum of non-destructive testing (NDT) personnel, inspectors, and technicians involved in weld inspection, as well as inspection of castings and forgings, both during fabrication and in-service. This comprehensive training programme equips participants with the knowledge, skills, and techniques required to effectively perform Magnetic Particle Testing (MT) and other NDT methods in various industrial settings. Participants learn to identify and evaluate surface and near-surface flaws in ferromagnetic materials, ensuring the integrity and quality of welded joints, castings, and forgings throughout their lifecycle.

Training Done In Accordance With the Requirements of BS EN ISO 9712

Training in accordance with the requirements of BS EN ISO 9712 is crucial for ensuring consistency, reliability, and competency in non-destructive testing (NDT) methods like Magnetic Particle Testing (MT). This international standard outlines the requirements for the certification of personnel performing non-destructive testing, including training, examination, and certification procedures. Adhering to these requirements ensures that technicians receive standardised training based on industry best practices and guidelines. By following BS EN ISO 9712, organisations can maintain high-quality testing practices, improve safety, and enhance the integrity of their products and structures. Additionally, conformity to this standard facilitates international recognition and acceptance of certifications, promoting interoperability and trust among stakeholders across different regions and industries. Overall, training in accordance with BS EN ISO 9712 plays a fundamental role in upholding the quality and reliability of non-destructive testing (NDT) operations.

Requirements

For entry into the course, there are no mandatory prerequisites. However, participants must fulfil training and certification requirements. The training duration, encompassing both theoretical learning and practical exercises, varies depending on the level of certification sought. Level 1 certification necessitates a minimum of 16 hours of training, while Level 2 requires 24 hours. Direct Level 2 certification, which skips Level 1, mandates 40 hours of training. These training hours are met by attending TWI's training courses. Certification also requires a minimum duration of practical experience either prior to or following successful completion of the qualification examination. For Level 1, one month of experience is required, while Level 2 requires three months. Direct Level 2 certification demands four months of experience. These requirements ensure that candidates are adequately trained and experienced to perform magnetic particle testing with competency respective to their certification levels.

What Will You Learn?

Throughout this course, participants will receive comprehensive instructions on the foundational principles of magnetism, including magnetic fields, induction, permeability, and reluctance. They will take a deep dive into the complexities of the lines of force, various testing methodologies, and the subtle interpretation of inspection indications. Practical exercises will offer hands-on experience, allowing participants to apply the newly gained knowledge in real-time scenarios. In addition to that, the course will cover demagnetisation techniques to ensure the integrity of test results. Participants will also learn methods for assessing sensitivity, a critical aspect of magnetic particle testing. Furthermore, instruction writing will be emphasized, equipping participants with the skills needed to communicate inspection procedures effectively. By the end of the course, participants will have a comprehensive understanding of magnetic particle testing principles and techniques, empowering them to conduct thorough and accurate inspections in a variety of industrial contexts.
