🎯 Key points for quick navigation:
01:32 *🧲 Basics of Magnetic Particle Method*
- Magnetic particles are used for detecting surface and near-surface discontinuities in ferromagnetic materials.
- The method is crucial for detecting superficial and near-surface discontinuities.
- Understanding the concept of magnetic field leakage and its relation to discontinuity detection.
03:24 *🔍 Magnetic Domains and Saturation*
- Ferromagnetic materials consist of magnetic domains that align when the material is magnetized.
- Saturation occurs when all magnetic domains are aligned, and no increase in magnetic field can induce more alignment.
- Knowledge of magnetic permeability is essential in understanding material magnetization.
07:11 *🧲 Magnetic Poles and Magnetic Field Characteristics*
- Magnetic poles have distinct characteristics in the flow of magnetic field lines.
- Understanding the flow of magnetic lines from south to north and their behavior in different material sections.

12:01 *🌡️ Advantages & Disadvantages of Magnetic Particle Testing*
- Magnetic particle testing is an easy, practical, and cost-effective method for flaw detection.
- The need for cleanliness before inspection and its practicality compared to other testing methods.
- Limitations and challenges of magnetic particle testing, including material restrictions and safety measures.
21:15 *🧲 Relationship between current and magnetic field*
- Understanding the relationship between current (i) and magnetic field (b) helps determine magnetic properties.
- The hysteresis curve reflects the magnetic properties of materials.
- Analyzing hysteresis curves helps determine material characteristics for testing.
23:06 *🔗 Understanding hysteresis curve morphology*
- Exploring the hysteresis curve stages from demagnetization to magnetic saturation.
- Differentiating magnetically saturated points and residual magnetism.
- Applying coercive force to remove residual magnetism in materials.
30:39 *💡 Classification of materials based on magnetic permeability*

- Understanding how magnetic permeability affects material properties.
35:23 *🧲 Classification of magnetic materials*
- Identifying characteristics of ferromagnetic, paramagnetic, and diamagnetic materials.
- Examples and behaviors of each type of magnetic material.
- Explaining why certain materials are suitable or unsuitable for magnetic particle testing.
42:39 *🧲 Electromagnetic Yoke Technique*
- Electromagnetic yoke technique for magnetic particle inspection,
- Enables inspection of medium to large-sized parts by inducing a longitudinal magnetic field between its poles.
46:57 *🔍 Magnetization Direct Techniques*
- Different techniques for direct magnetization,
- Inspection of welds, forgings, and castings with the contact tip technique.
49:09 *🌀 Longitudinal Magnetization Technique*
- Applying a longitudinal magnetic field with coils or cables,
- Ideal for detecting transverse discontinuities in components.
50:34 *💡 Conductor Central Magnetization Technique*
- Magnetization of hollow cylindrical parts using a secondary conductor,
- Effective for hollow components like pipes, rings, and bearings.
01:04:03 *🧲 Detection of Surface Discontinuities with AC Current*
- AC current is ideal for detecting surface discontinuities like fatigue cracks.
- The sinusoidal waveform of AC current creates pulsations that aid in particle mobility.
- It is recommended for inspecting components in service for surface imperfections.
01:06:35 *🔌 Obtaining DC Current from AC*
- Rectification of AC current using diodes yields pulsed DC current.
- Full-wave rectification with a bridge rectifier generates unidirectional DC current.
- This method is useful for creating a pulsating magnetic field with maximum sensitivity for subsurface discontinuities.
01:08:36 *🔋 Characteristics of Full-Wave Rectified DC*
- Full-wave rectified DC provides high penetration and low particle mobility.
- Ideal for residual magnetization in detecting subsurface discontinuities.
- Selection of magnetizing current type should align with the type of imperfection being sought.
01:12:06 *🌌 Classification of Magnetic Particles*
- Magnetic particles can be dry or suspended in a liquid.
- They must possess specific characteristics like high permeability and low reactivity.
- Dry magnetic particles are suitable for detecting subsurface discontinuities with good mobility.
01:13:08 *💦 Characteristics of Dry Magnetic Particles*
- Dry particles should be used as supplied or by spraying, not for overhead applications.
- They lack effectiveness in detecting fine discontinuities and require particles to remain on the surface for a few seconds.
- Dry particles are not recommended for vertical or overhead surface inspection.
01:16:08 *🌊 Features of Wet Magnetic Particles*
- Suspended in water or light petroleum, wet particles are ideal for fine discontinuity detection.
- They need proper suspension control and may be supplied in aerosol cans.

Excelente!
Buenos día compañero José Luis ante todo reciba un cordial saludo, quiera agradecer por tan excelente material audiovisual y a su vez quisiera saber si tiene disponible dentro de su biblioteca material disponible sobre un curso UT nivel II. Muchas gracias dejo mi mail por si puede ayudarme, feliz día
Hola buenas tardes. Pablo consulta. Como saber que tipo de isntrumento de particulas tengo que aplicar para realizar el ensayo.
Vi que existen varios equipos yo solo conosco el yugo.
Una pregunta la únion de soldadura es considerado como indicación relevante o irrelevante . Gracias
Excelente el curso , donde puedo acceder a la parte B ?
buenisimo
excelente
Buenas Noches Estimado, me gustaría adquirir el manual desde ya muchas gracias!
muy buen video quiero los examenes como los podria adquirir
Ya que cuando se realiza la reparación de una grieta en una pieza de acero m marca el contorno de soldadura y m están rechazando la pieza.
Una pregunta, en una pieza magnetizada a partir de cuantos gaus se afecta el arco de la soldadura?
Según mi experiencia como soldador, sobre los dos Gauss
@@gonzaloiturrieta5169 2 gaus no creo. yo he trabajado un ducto y los caños tenían entre 4 y 10 gaus la mayoría y no teníamos problemas, pero había algunos que superaban los 20 gaus, mas no podía medir porque el instrumento solo medía hasta 20, y creo que ahí había algunos problemas, pero que tampoco fueron tan graves. igualmente sigo interesado en buscar información o literatura sobre el tema.
Cómo puede tener tu correo ya que m interesa mucho tus cursos
Alguién tiene test de exámen? Gracias.
Les agradecería su respuesta
