The Permanent Magnet Yoke for Magnetic Particle Inspection manufactured by NDE FLAW TECH INDIA is a high-performance portable magnetic inspection device designed for the rapid detection of surface and near-surface discontinuities in ferromagnetic materials without requiring an external electrical power source. Engineered for field applications, remote inspection locations, hazardous environments, and confined spaces, the permanent magnet yoke provides a reliable and cost-effective solution for magnetic particle testing where portability, simplicity, and operational safety are essential.

Unlike conventional electromagnetic yokes, the Permanent Magnet Yoke generates a constant magnetic field using high-energy permanent magnets. This eliminates the need for electrical power, batteries, or external cables, making it particularly suitable for on-site inspections in locations where electricity is unavailable or restricted. The yoke is widely used for weld inspections, structural fabrication, pressure vessel examination, pipeline inspection, casting inspection, forging inspection, and preventive maintenance activities.

Manufactured using premium-grade magnetic materials and durable mechanical components, the yoke is designed to deliver stable magnetic field strength with excellent durability and long service life. The ergonomic construction allows inspectors to perform inspections efficiently with minimal operator fatigue while maintaining consistent lifting capability and reliable magnetic performance.

The Permanent Magnet Yoke is compatible with both dry and wet magnetic particle inspection techniques and can be used with visible or fluorescent magnetic particles depending on the inspection procedure. Its adjustable articulated legs allow inspection of flat, curved, irregular, and welded surfaces, providing excellent versatility across a wide range of industrial applications.

NDE FLAW TECH INDIA manufactures permanent magnet yokes under stringent quality control procedures and offers standard models as well as customized designs to meet specific customer requirements. Our engineering team also provides technical support for selecting the appropriate yoke configuration based on component geometry, inspection requirements, and applicable industry standards.
