Fatigue cracks start small: at a weld toe, an arc strike, a sharp fillet radius. Under cyclic load they grow until the remaining section can no longer carry it. On ferromagnetic steel the tightest surface-breaking crack can be invisible to the eye and still be structurally critical. Visual inspection alone will not find it.
Magnetic particle inspection magnetises the component and applies fine ferromagnetic particles. Flux leakage at a discontinuity pulls the particles into a sharp, visible indication in seconds. The technique is governed by ASME Section V Article 7 and ISO 9934, with acceptance evaluated against the applicable construction code.
Glospech MPI teams work on live plant across Gauteng and Mpumalanga: pressure vessel and piping welds, structural steel, castings, forgings, shafts and machined components. Indications are marked and evaluated on site, with a written report within 24 hours.

Visible Colour-Contrast MPI
AC yoke magnetisation with black magnetic ink over white contrast paint
Ideal for site work in daylight: welds, structural steel, castings and forgings
Detects surface-breaking and slightly subsurface discontinuities
Code: ASME Section V Article 7 / ISO 9934 / ISO 17638
What MPI detects
Weld toe and HAZ cracks · Fatigue cracks · Laps, seams and cold shuts · Surface lack of fusion · Near-surface inclusions
Fluorescent MPI (UV-A)
Fluorescent particles viewed under UV-A light in darkened conditions
Higher sensitivity for fine, tight discontinuities
Suited to machined components, shafts and critical welds
Demagnetisation and post-clean verification on completion
Applicable codes
