What is Liquid Penetrant?

Liquid penetrant testing (LPT) is a widely used non-destructive testing (NDT) method used to detect surface-breaking defects in non-porous materials. A liquid dye is applied to the surface of the part being inspected, allowed to penetrate any flaws, excess penetrant is removed, and then a developer is applied to draw the penetrant out of the flaws, making them visible to the inspector.

Liquid Penetrant Competitor Technologies

Magnetic Particle

Magnetic particle testing is a surface inspection method like liquid penetrant, used to detect cracks and flaws. Hence, it is a competitor.

Eddy current testing, while more versatile in materials it can inspect, is another NDT method used to detect surface and near-surface flaws, making it a competitor to liquid penetrant testing.

Radiography, like liquid penetrant, is an NDT method for detecting flaws. It can detect subsurface flaws, making it a broader inspection technique, and a competitor to liquid penetrant.

Ultrasonic testing, similar to radiography, is an NDT method that can detect subsurface flaws and can be used as an alternative method of inspection, making it a competitor.

Ultrasonics testing, similar to radiography, is an NDT method that can detect subsurface flaws and can be used as an alternative method of inspection, making it a competitor.

Radiographic testing, like liquid penetrant, is an NDT method for detecting flaws. It can detect subsurface flaws, making it a broader inspection technique, and a competitor to liquid penetrant.

Ultrasonic Testing

Ultrasonic testing, similar to radiography, is an NDT method that can detect subsurface flaws and can be used as an alternative method of inspection, making it a competitor.

Digital Radiography

Digital radiography is a type of radiography, which is an NDT method for detecting flaws. It can detect subsurface flaws, making it a broader inspection technique, and a competitor to liquid penetrant.
