NDT METHODS
Liquid Penetrant Testing
Penetrant Testing (PT) offers non-destructive testing for surface flaws in non-porous materials like metals and ceramics.
- Type 1 (Fluorescent Penetrants): High-sensitivity options (Levels ½–4) that glow under UV light for detecting fine cracks; suited to aerospace turbine blades, power generation components, and high-end automotive parts where precision is essential.
- Type 2 (Visible Dye Penetrants): Low-sensitivity (Level 1), cost-effective methods visible under white light; ideal for routine inspections of welds, castings, and forgings in automotive manufacturing, oil & gas pipelines, and construction infrastructure to identify defects like leaks or porosity.
PT is limited to surface-breaking flaws but supports quality control across industries.
Magnetic Particle Testing
Magnetic Particle Testing (MT) offers non-destructive testing for surface and near-surface flaws in ferromagnetic materials like steel and iron.
- Fluorescent Particles: High-sensitivity method using UV light to reveal fine cracks and discontinuities; ideal for critical applications in aerospace components, power generation turbines, and high-end automotive parts where precision detection is vital.
- Visible Particles: Cost-effective, color-contrast approach visible under white light; suited for routine inspections of welds, castings, and forgings in automotive manufacturing, oil & gas equipment, and construction structures to identify defects like seams or inclusions.
MT ensures quality control across industries, limited to ferromagnetic materials and flaws within 1-2 mm of the surface.
Ultrasonic Testing
Ultrasonic Testing (UT) provides non-destructive evaluation of internal flaws and material thickness using high-frequency sound waves in metals, composites, and other solids.
- Straight Beam (0 Degree): Compression wave technique for precise thickness gauging and detecting laminar defects or voids; ideal for corrosion monitoring in oil & gas pipelines, structural integrity checks in construction, and quality control in automotive manufacturing.
- Angle Beam: Shear wave method using angled probes to identify cracks, lack of fusion, and inclusions in welds; suited to inspecting pressure vessels in power generation, aerospace components, and high-end fabrication where volumetric flaw detection is essential.
UT supports quality assurance across industries, effective for subsurface defects but requires skilled operators and surface preparation.
Eddy Current Testing
Eddy current inspection is a non-destructive testing method that uses electromagnetic induction to detect surface and near-surface flaws, measure material properties, and assess the condition of conductive materials.
It works by inducing circulating electrical currents (eddy currents) in a conductive material using an alternating magnetic field created by a probe. Variations in these eddy currents, caused by defects or material property changes, are then detected and analyzed to reveal information about the material's integrity
