X-rays or gamma rays are used to create images of the internal structure of a weld. This method detects internal defects like cracks, porosity, and lack of fusion.

• Ultrasonic Testing:

Ultrasonic waves are used to inspect welds for internal defects. The reflections are analyzed to identify defects like cracks and lack of fusion.

• Magnetic Particle Testing:

This method detects surface and near-surface defects in ferromagnetic materials. Magnetic particles are applied to the surface, and a magnetic field attracts the particles to areas with defects.

• Liquid Penetrant Testing:

This method involves applying a liquid penetrant to the surface of the weld, allowing it to seep into surface-breaking defects. 

• Eddy Current Testing:

Eddy current testing is suitable for detecting surface and near-surface defects. It involves inducing eddy currents in the material and measuring changes in the electromagnetic field caused by defects.

• Phased Array Ultrasonic Testing:

This advanced form of ultrasonic testing uses multiple ultrasonic elements to steer, focus, and scan beams electronically. It provides detailed information about the size and location of defects.

• Radiographic Film Interpretation:

Trained personnel interpret radiographic films to identify and evaluate weld defects based on the images produced during radiographic testing.

The choice of the NDT method depends on factors such as the type of material, the welding process used, the weld's size and configuration, and the inspection's specific requirements. A combination of NDT methods may often be employed to thoroughly assess the welded joint's quality.
