non-destructive testing

what is ndt?

NDT Testing, or Non-Destructive Testing, is a methodical process of inspecting, testing, and evaluating materials, components, and structures without causing damage. It employs various techniques such as ultrasonics, radiography, and visual examination to detect defects, assess quality, and ensure safety and reliability across diverse industries. NDT plays a crucial role in maintaining the integrity of critical assets and infrastructure.

NDT

Magnetic Particle Inspection

Magnetic particle inspection (MT) is a non-destructive testing method used to detect surface and slightly subsurface flaws in ferromagnetic materials (such as carbon steel). It is used routinely to inspect welds, piping, pressure vessels and structural steel components.

MT Advantages

Sensitivity to Surface Defects
Rapid Inspection
Real-time Results

NDT

Liquid Penetrant Inspection

Liquid Penetrant Testing (PT) is used to detect casting, forgings, and welding surface defects such as hairline cracks, surface porosity, leaks in new products, and fatigue cracks on in-service components. PT is a non-destructive examination method used to locate surface breaking discontinuities in non-porous materials (metals, plastics, or ceramics).

This method may be applied to ferrous and non-ferrous materials, although for ferrous components magnetic-particle inspection is often used instead for its subsurface detection capability.

PT Advantages

Cost-Effective
Minimal Surface Preparation
Sensitivity

NDT

Ultrasonic Inspection

Ultrasonic Inspection is a non-destructive testing method capable of detecting both surface and sub-surface flaws in components and welds. UT can also be used to measure the thickness of materials, a common method of evaluating metal losses due to corrosion or erosion.

Ultrasonic Advantages

Depth Assessment
No Hazardous Radiation
Early Detection

Other NDT Methods

Positive material identification

Positive Material Identification is a process used to determine the chemical composition of materials, typically metals and alloys.

PMI helps ensure that the correct materials have been used in construction or manufacturing, and it can also identify potential issues such as material degradation or contamination. This method is essential for quality control and safety, especially in industries where material integrity is critical.

Optical Emissions Spectrometry

Optical Emission Spectroscopy, or OES analysis, is a rapid method for determining the elemental composition of a variety of metals and alloys. The newest handheld models have made CE testing more compact and affordable.

hardness testing

Hardness testing is a non-destructive test method that involves applying a constant load via a rounded or pointed object, under controlled conditions, to create an indentation in a metal surface. This is then measured to determine the hardness of the material.

Ferrite testing

Ferrite testing, also referred to as a ferrite scope test, is a rapid non-destructive inspection method used to measure the amount of delta ferrite in austenitic stainless steel and duplex stainless-steel materials. Ensuring proper ferrite content ensures corrosion resistance, durability, and crack prevention.
