Ultrasonic testing is a non-destructive method that uses high-frequency sound waves to detect internal weld flaws.
Visual inspection checks for surface defects like cracks, undercuts, porosity, and dimensional accuracy.
Magnetic Particle Testing is effective for detecting cracks and discontinuities in ferromagnetic materials.
Radiographic testing uses X-rays or gamma rays to detect internal flaws like porosity and cracks in welds.
Impact testing (e.g., Charpy test) measures the material’s ability to absorb energy and resist fracture.
Tensile testing is destructive as it involves pulling the sample until it fractures.
Liquid Penetrant Testing reveals surface-breaking defects by using a dye that enters cracks and becomes visible under light.
Weld inspection does not change weld composition; it ensures quality by identifying issues and verifying compliance.
Hardness testing measures how resistant a material is to deformation from indentation or penetration.
Radiography is effective for thick welds because it can reveal internal discontinuities not visible on the surface.
