🛠️ NDT Services – Ensuring Structural Integrity with Precision
At Lady Dona Infra Projects Limited, we specialize in providing high-quality Non-Destructive Testing (NDT) services that ensure the safety, reliability, and durability of materials and structures—without causing any damage. Our certified technicians use advanced equipment and internationally recognized standards to detect hidden flaws, assess structural integrity, and support proactive maintenance strategies.
🧪 Our Core NDT Methods
1. Ultrasonic Testing (UT)
We use high-frequency sound waves to detect internal discontinuities in welds, castings, and forged components.
Applications: Weld inspection, thickness gauging, flaw detection in structural steel.
2. Radiographic Testing (RT)
Utilizing X-rays or gamma rays, we examine internal structures to detect subsurface defects.
Applications: Pressure vessels, pipelines, castings.
3. Magnetic Particle Testing (MPT/MT)
This method detects surface and near-surface discontinuities in ferromagnetic materials by applying magnetic fields and ferrous particles.
Applications: Weld joints, bolts, axles.
4. Liquid Penetrant Testing (LPT/PT)
A colored or fluorescent dye is used to reveal surface cracks and defects on non-porous materials.
Applications: Non-ferrous metals, ceramics, plastics.
5. Visual Testing (VT)
Our trained inspectors use direct and remote visual examination tools to assess surface conditions.
Applications: Weld quality, surface corrosion, structural deformation.
6. Eddy Current Testing (ET)
Ideal for detecting surface and near-surface flaws in conductive materials without removing coatings or insulation.
Applications: Aerospace, heat exchanger tubes, marine components.
