The specific NDE (non-destructive examination) method(s) you should take first will depend on your specific career goals and the industry you plan to work in. However, here are a few commonly used NDE methods that are considered to be a good starting point for beginners:

• Visual Inspection: This is the most basic and widely used NDE method. It involves using the naked eye to inspect materials and structures for signs of damage or defects. Visual inspection is relatively simple and requires minimal equipment, making it a good starting point for beginners.
• Dye Penetrant Inspection (DPI): This method involves applying a liquid dye to the surface of a material, which is then drawn into any surface-breaking cracks or defects. The dye is then removed and a developer is applied, which causes the dye to reappear, highlighting the defects. DPI is a relatively simple method, and is widely used to detect surface-breaking defects in a variety of materials.
• Magnetic Particle Inspection (MPI): This method involves applying a magnetic field to a material, which causes magnetic particles to be attracted to any surface-breaking defects. The particles are then visible under a UV light. MPI is widely used to detect surface-breaking defects in ferromagnetic materials.
• Ultrasonic Testing (UT): This method involves using high-frequency sound waves to inspect materials and structures for internal defects. UT is a more advanced method and requires specialized equipment, but it can be used to detect subsurface defects in a variety of materials.

It's important to note that many NDE methods have specific applications, and some are more suited for certain industries than others. It's best to research the different methods and find out which are most relevant to your industry and career goals.

There are several advanced NDE (non-destructive examination) methods that are used to evaluate the properties of materials and structures in a more precise and detailed way. Some examples include:

• Radiographic Testing (RT): This method involves using X-rays or gamma rays to create an image of the internal structure of a material or component. RT is used to detect internal defects, such as voids, inclusions, and cracks, in a wide range of materials, including metals, plastics, and ceramics.
• Eddy Current Testing (ECT): This method involves passing an alternating current through a conductor, which creates a magnetic field around the conductor. Any defects or variations in the material will affect the magnetic field, which can be detected by sensors. ECT is used to detect surface and subsurface defects in conductive materials, such as metals.
• Thermography: This method involves using infrared cameras to create images of the surface temperature of a material or component. Any variations in temperature can indicate the presence of defects or issues, such as insulation deficiencies, loose connections, and overheating components.
• Acoustic Emission Testing (AE): This method involves monitoring the sound waves emitted by a material or component while it is under stress. Any changes in the sound waves can indicate the presence of defects, such as cracks or other damage.
• Computed Tomography (CT) : This method uses X-ray sources and detectors to create a 3D image of the internal structure of an object. It is commonly used in medical imaging but can be adapted for industrial uses such as aerospace, automotive and heavy industries.

These are just a few examples of advanced NDE methods. There are many other specialized NDE methods that are used in specific industries and applications. These methods are more complex and require specialized training and equipment, but they can provide more detailed and accurate information about the condition of materials and structures.

There are several certified programs in NDE (non-destructive examination) that are offered by various organizations and institutions. These programs typically provide training and certification in various NDE methods, such as visual inspection, ultrasonic testing, radiographic testing, and magnetic particle inspection. Here are a few examples of certified programs in NDE:
