DESTRUCTIVE TESTING SERVICES
1. Tensile Test:
Purpose: To determine the mechanical properties of a material under tension.
Procedure: A specimen is subjected to an increasing axial load until it fractures. The load and deformation data are recorded.
Key Parameters: Ultimate tensile strength, yield strength, elongation, and reduction in area.
2. Bend Test:
Purpose: To assess the ductility and soundness of a material by bending it.
Procedure: A specimen is bent to a specified angle, and any cracks or defects are observed.
Applications: Commonly used for weld qualification and assessing material quality.
3. Macroscopic Examination:
Purpose: To visually inspect the surface and internal features of a material.
Procedure: The material is examined under a microscope or with the naked eye.
Detects: Surface defects, inclusions, cracks, and other irregularities.
4. Microscopic Examination:
Purpose: To study the microstructure of a material.
Procedure: Thin sections of the material are prepared and observed under a microscope.
Reveals: Grain size, phase distribution, and presence of defects.
5. Chemical Analysis:
Purpose: To determine the chemical composition of a material.
Techniques: Spectroscopy, wet chemical methods, and elemental analysis.
Identifies: Elements and compounds present.
6. Hardness Tests:
Purpose: To measure a material’s resistance to indentation or scratching.
Common Methods: Rockwell, Brinell, Vickers, and Knoop hardness tests.
Applications: Material selection, quality control, and heat treatment assessment.
7. Charpy Impact Test:
Purpose: To evaluate a material’s toughness and resistance to sudden impact.
Procedure: A notched specimen is struck by a pendulum, and the energy absorbed during fracture is measured.
Commonly Used for: Assessing the impact behavior of metals and polymers.
8. Z Test :
Purpose: To compare sample means with a known population mean.
Statistical Method: Compares the sample mean to the population mean using the standard deviation.
Applications: Quality control, hypothesis testing, and process improvement.
9. Fastener Testing:
Purpose: To evaluate the strength and performance of fasteners (bolts, nuts, anchors, rods, etc.).
Tests: Tensile, shear, and fatigue tests.
Ensures: Safe and reliable connections in structures.
10. Fracture Test:
Purpose: To understand the fracture behavior of a material.
Procedure: A specimen is loaded until it fractures, and the fracture surface is examined.
Types: Ductile, brittle, and mixed-mode fractures.
These tests play a crucial role in ensuring material quality, safety, and performance across various industries
