Magnetic Testing (MT)

Course Overview:

Magnetic Testing (MT), also known as Magnetic Particle Testing, is a crucial technique in Non-Destructive Testing (NDT) utilized to detect surface and near-surface defects in ferromagnetic materials. This course provides participants with a comprehensive understanding of MT principles, equipment operation, inspection techniques, and interpretation of test results. Through a combination of theoretical knowledge and practical exercises, participants will develop the skills necessary to perform MT effectively in various industrial applications.

Course Objective

Understanding MT Principles: Gain insight into the principles of magnetic particle testing, including magnetic field generation, particle application, and defect detection mechanisms.
Equipment Operation and Setup: Learn to operate MT equipment proficiently, including magnetizing equipment, yokes, coils, and magnetic powders.
Inspection Techniques: Acquire proficiency in conducting MT inspections using both direct and indirect magnetization methods, including longitudinal and circular magnetization.
Interpretation of Test Results: Develop skills in interpreting magnetic particle indications, distinguishing between relevant defects and surface irregularities, and assessing the severity of detected discontinuities.
Safety and Quality Assurance: Understand safety precautions associated with MT, including handling of magnetic fields and powders, and adhere to quality assurance protocols for reliable inspection outcomes.
