Magnetic Particle Testing (MT) Services – Surface Crack Detection with Speed and Accuracy

Magnetic Particle Testing (MT) is a rapid and dependable non-destructive testing (NDT) technique used to detect surface and near-surface flaws in ferromagnetic materials. At Quality Concept Welding Solutions Pvt. Ltd., we deliver high-quality MT inspection services to identify critical discontinuities such as cracks, laps, seams, and lack of fusion in welded and machined components.

What is Magnetic Particle Testing?

MT involves magnetizing the test object and applying iron particles (either dry powder or liquid suspension). When a surface or sub-surface defect interrupts the magnetic field, it causes the particles to gather at the discontinuity, forming a visible indication. This makes MT ideal for identifying hidden surface flaws quickly and accurately in iron, carbon steel, and other magnetic alloys.

Applications of Magnetic Particle Testing

MT is widely used in various industries to inspect:

• Weld Inspection: Detect surface cracks, toe cracks, and lack of fusion in weld joints
• In-Service Inspection: Fast evaluation during maintenance of components and equipment
• Forgings & Castings: Identify laps, seams, and shrinkage cracks in manufactured parts
• Machined Parts: Inspect shafts, gears, pins, bolts, and high-stress components
• Heat-Affected Zones: Examine weld HAZ areas for surface discontinuities post-welding

Key Benefits of Magnetic Particle Testing

• Early Detection: Identifies small surface or near-surface defects before they lead to failure
• Fast & Efficient: Provides immediate results for on-the-spot decision-making
• No Disassembly Needed: Often performed without removing components from service
• Cost-Effective: Ideal for inspecting large volumes of parts in less time
• Versatile: Suitable for welds, castings, machined parts, and heavy structural elements
