Magnetic Particle Testing (MT / MPI) Services
Precision Magnetic Particle Testing (MT/MPI) for detecting surface and near-surface cracks in ferromagnetic welds, forgings, and machined components. Testing is performed by appropriately qualified and certified NDT personnel in accordance with applicable codes, standards, specifications, and approved procedures.
Principle & Testing Methodology
Magnetic Particle Testing induces a magnetic field into a ferromagnetic component using electromagnetic AC/DC yokes or prods. Surface-breaking or near-surface discontinuities disrupt the magnetic flux lines, creating localized magnetic leakage fields that attract finely divided ferromagnetic particles (visible black or fluorescent green under UV-A light).
Defects & Discontinuities Detected
- Fatigue cracks and grinding checks
- Quench cracks in heat-treated steels
- Forging laps, seams, and flash line tears
- Weld toe cracks and heat-affected zone (HAZ) fissures
- Root and capping passes weld porosity
Typical Industrial Applications & Components
- Automotive crankshafts, steering knuckles, and connecting rods
- Overhead crane hooks, hoist drums, and lifting lugs
- Structural steel fillet welds and gusset plates
- Forging hammer rams, press columns, and die blocks
Applicable Materials
Carbon steels, low-alloy steels, tool steels, and ferromagnetic cast irons (non-applicable to austenitic stainless steel or aluminum).
