NON DESTRUCTIVE TEST

MP provides technical labor specialized in Non-Destructive Testing, some of them are:

Ultrasound

Detects internal discontinuities in materials, based on the phenomenon of reflection of acoustic waves, when they encounter obstacles to their propagation, inside the material.

Ultrasound is also used to measure thickness and to determine corrosion with extreme ease and precision.

The applications of this test are numerous: welds, laminates, forged, cast, ferrous and non-ferrous, metal alloys, glass, rubber, composite materials, among others.

Penetrating Liquid

The Penetrating Liquids test is considered one of the best test methods for detecting surface discontinuities of non-porous materials, such as: ferrous and non-ferrous metals, aluminum, metal alloys, ceramics, glass, certain types of plastics or organic materials -synthetics.

Penetrating liquids are also used to detect leaks in tubes, tanks, welds and components.

Discontinuities in molten materials, such as: cold drop, tension crack caused by tempering or tempering processes, manufacturing or process discontinuities such as cracks, seams, double lamination, overlap of material or cracks caused by machining, or fatigue of the material or even corrosion under stress, can be easily detected by the Penetrating Liquid method. -

MP has a team with the ability to inspect products in "Magnaflux".

Magnetic Particle

The test method is based on the generation of a magnetic field that runs through the entire surface of the ferromagnetic material.

The magnetic lines of the flow induced in the material, deviate from their trajectory when encountering a superficial or sub-superficial discontinuity, thus creating a region with magnetic polarity, highly attractive to magnetic particles.

The moment this magnetization is caused in the piece, the magnetic particles are applied over the piece, which will be attracted to the location of the surface that contains a discontinuity, thus forming a clear indication of defect.

The magnetic particle test is used to detect surface and sub-surface discontinuities in ferromagnetic materials.

Defects are detected, such as: cracks, cold joints, inclusions, cold drops, double lamination, lack of penetration, folding, segregation, etc.
