At High Technology Nondestructive Testing Service Co., Ltd, we provide Magnetic Particle Testing (MT)—one of the most effective and sensitive methods for detecting surface and near-surface discontinuities in ferromagnetic materials. Whether in the workshop or on-site at a construction project, our MT services ensure the structural integrity of welds, castings, and forged components.
Our Specialized MT Techniques
We offer a variety of magnetic testing methods tailored to the specific environment and sensitivity requirements of your project:
-
Visible Wet/Dry Method: Using high-contrast colored particles (typically white background with black particles) for rapid on-site inspections in daylight.
-
Fluorescent Magnetic Particle Testing: Utilizing specialized UV-A light sources and fluorescent particles for maximum sensitivity in detecting extremely fine, tight cracks that are invisible to the naked eye.
-
Electromagnetic Yoke & Prods: Portable equipment allowing for flexible inspection of complex geometries, structural steel, and pressure vessel welds.
Why Choose MT from HTNDT?
-
Superior Surface Sensitivity: MT is significantly more sensitive than visual inspection for detecting fatigue cracks, stress corrosion cracking, and grinding cracks.
-
Immediate Results: Indications are visible instantly on the surface of the part, allowing for immediate repair and re-testing without project delays.
-
Versatility: Highly effective on all ferromagnetic materials, including carbon steel, low-alloy steel, and cast iron.
Technical Compliance & Quality Assurance
Our technicians are experts in identifying and characterizing magnetic indications to prevent “false calls” while ensuring no critical defects are missed.
-
Certified Expertise: Inspections are conducted by ISO 9712 / ASNT Level II or III certified personnel.
-
Industry Standards: Fully compliant with ASME Section V (Article 7), ASTM E709, ISO 9934, and AWS D1.1.
-
Comprehensive Reporting: We provide detailed maps and photographic evidence of all findings, ensuring 100% traceability for your quality records.
