Magnetic Particle Testing Services

At Kova Engineering (Saskatchewan) Ltd., we offer comprehensive Magnetic Particle Testing Services to detect surface and near-surface defects in ferromagnetic materials with precision and reliability. Our services are essential for ensuring the structural integrity and operational safety of critical components across different industries. Backed by over 30 years of field-tested experience, our certified inspectors use both portable and in-house equipment to conduct accurate, efficient, and code-compliant examinations. Our Magnetic Particle Testing Services help to identify defects before they lead to failure, minimizing unplanned downtime and maintaining equipment performance.

We tailor each inspection to meet the unique conditions of the project—whether dry powder, wet visible, wet fluorescent, or yoke testing methods are needed. With deep knowledge of industry standards and material behaviors, we provide clients with actionable results that support quality control, preventive maintenance, and regulatory compliance.

Expertise in Magnetic Particle Testing Services

Kova Engineering (Saskatchewan) Ltd. delivers industry-proven Magnetic Particle Testing Services performed by MT Level 2 certified professionals. Our team is skilled in applying multiple MPI techniques to identify cracks, laps, seams, and other discontinuities that may not be visible to the naked eye. Every inspection is performed in strict accordance with codes such as ASTM E709, ASME Section V, CSA W59, and client-specific specifications.

Our expertise in Magnetic Particle Testing Services include selecting the optimal testing method for the application—ranging from dry visible inspections for coarse welds and castings to high-sensitivity fluorescent testing for fine surface cracks. We also specialize in field-ready yoke testing for irregular components and hard-to-access areas. The combination of advanced training, detailed procedure execution, and precise interpretation allows us to provide clients with accurate defect detection and dependable reporting.

Advantages of Magnetic Particle Testing (MT)

Effective for Surface and Slightly Subsurface Flaws: MT excels at spotting cracks, seams, and other discontinuities right at or just below the surface of ferromagnetic materials.
Cost-Efficient: Compared to other non-destructive testing methods, MT offers reliable results at a lower cost.
Highly Versatile: MT works across a wide range of ferromagnetic materials—like iron, nickel, cobalt, and their alloys—and adapts well to parts of various shapes and sizes, from bolts to bridges.
Fast and Straightforward: The process is quick and easy to perform, making it ideal for high-throughput or time-critical inspections.
Instant Feedback: Inspection results are visible on the spot, enabling immediate decisions about repair, rejection, or approval.

Dry Visible (Dry Powder)

Dry Visible Magnetic Particle Testing, commonly referred to as the Dry Powder method, is a proven NDT technique for inspecting ferromagnetic materials, especially effective on rough, large, or irregular surfaces. In this method, finely milled ferromagnetic particles—typically colored for high visibility—are applied to a dry surface while the part is magnetized. These particles are attracted to areas of magnetic flux leakage, often caused by surface-breaking or near-surface discontinuities such as cracks, laps, or seams. The gathered particles outline the defect, allowing for immediate visual detection without the need for UV lighting or special conditions.

At Kova Engineering (Saskatchewan) Ltd., our certified MT Level 2 inspectors utilize Dry Powder MPI when conditions favor dry application, such as in-field environments, elevated temperatures, or coarse-textured components like castings and welds. Our team ensures precise magnetization techniques and proper particle application to maximize visibility and detection reliability.

Wet Visible ("Black and White")

Wet Visible Magnetic Particle Testing, often referred to as the “Black and White” method, uses a liquid suspension of ferromagnetic particles to detect flaws on ferromagnetic materials. This method involves first applying a white contrast paint to the surface, followed by the application of black iron particles suspended in a carrier fluid. When the material is magnetized, any flaws create flux leakage that draws in the black particles, making defects stand out clearly against the white background. The high contrast allows for reliable detection under visible light, eliminating the need for UV sources.

Kova Engineering (Saskatchewan) Ltd. uses the Wet Visible method in controlled shop environments or when fine detail is required on smooth surfaces. Our Level 2 certified inspectors are trained to apply contrast paint evenly, ensure optimal particle concentration in the suspension, and interpret results with precision. The technique is particularly effective for detecting tight, fine surface cracks or weld defects in fabricated steel components.

Wet Fluorescent ("Blacklight")

Wet Fluorescent Magnetic Particle Testing is one of the most sensitive and reliable methods for detecting very fine surface and near-surface discontinuities in ferromagnetic materials. This technique involves suspending fluorescent magnetic particles in a liquid carrier, which is then applied to the magnetized test surface. Under ultraviolet (UV-A) light—commonly referred to as blacklight—these particles fluoresce brightly, highlighting any areas of magnetic flux leakage, such as cracks, inclusions, or lack of fusion in welds.

At Kova Engineering (Saskatchewan) Ltd., our certified MT Level 2 inspectors utilize Wet Fluorescent MPI in controlled environments where precision and detection sensitivity are paramount. This method is particularly useful for high-stakes components where minute flaws can lead to critical failure if undetected. Our inspectors are trained in proper UV lighting use, suspension maintenance, and inspection timing to ensure high-contrast, unambiguous results.

Yoke Testing

Yoke Testing is a flexible, efficient Magnetic Particle Inspection method that uses a portable, handheld yoke to generate a magnetic field across the area under inspection. This makes it especially suitable for field inspections and for evaluating components with irregular shapes or limited access. The yoke creates localized magnetization, allowing for quick and effective surface defect detection, particularly cracks, seams, or fatigue-induced flaws.

At Kova Engineering (Saskatchewan) Ltd., our technicians are experienced in using AC and DC yoke methods depending on the inspection requirements. Yoke Testing is especially advantageous on-site, where larger MPI equipment may be impractical. Whether it’s structural steel, piping, or welded assemblies, our certified MT Level 2 inspectors ensure proper magnetic field application, particle visibility, and technique validation in every inspection. The portability and adaptability of yoke testing make it a dependable tool in construction, maintenance, and industrial service applications.
