Magnetic Crack Detection by Magkraft

This is an LED based UV flood light. It covers 400mmX200mm area and gives an intensity of 2500-3000uW/cm2 across the area at a distance of 15 inches from the lens. It operated directly from 220V Ac. It is very easy to integrate it in any MPI machine. The long life of LED ensures trouble free working for many years.

What is Magnetic Crack Detection?
Magnetic Crack Detection is a non-destructive testing
(NDT) method used extensively to discover surface
and near-surface discontinuities in ferromagnetic
materials. Think of it as a highly sensitive health
check for the metallic giants in industries like
aerospace,
automotive,
and manufacturing. By
applying a magnetic field to the metal, any crack or
flaw will disturb this field, creating a leakage visible
with the use of fine iron particles. It’s like sprinkling
pepper on soapy water to catch a breach – simple yet
highly effective.
HOW DOES IT WORK?
THE PROCESS CAN SEEM A BIT LIKE MAGIC, BUT IT’S ALL 
GROUNDED IN SCIENCE. HERE’S A QUICK BREAKDOWN:
• Magnetization: The first step involves magnetizing the
component. This can be done using a direct or indirect
method, depending on the shape and size of the
material.
• Application of Particles: Once magnetized, fine iron
particles, either dry or suspended in a liquid, are applied
to the surface of the component.
• Flaw Detection: If there are any cracks or defects, these
particles will gather and form visible indications at the
flaw sites due to magnetic leakage.
Why is

Crack 
Detection
a Game-
Changer?
EFFICIENCY
This method is incredibly efficient. It allows for the inspection of
large volumes of material in a relatively short amount of time,
making it ideal for high-volume production environments.
SENSITIVITY
Magnetic Crack Detection can find extremely fine cracks that
other methods might miss. This sensitivity makes it invaluable for
preventive maintenance, helping avoid catastrophic failures and
costly downtime.
VERSATILITY
It’s adaptable to various shapes and sizes of ferromagnetic
materials, which means it can be used in a myriad of
applications—from inspecting automotive parts to ensuring the
integrity of structural components in skyscrapers.
Real-World Applications
The Bottom Line
The real-world applications of Magnetic Crack 
Detection are vast and impressive. In the 
aerospace industry, it ensures the structural 
integrity of aircraft parts, which are subject to 
extreme environmental conditions.
Magnetic Crack Detection is more than just a 
maintenance tool; it’s a cornerstone technology 
in the realm of industrial safety and efficiency. 
By enabling early detection of potential 
problems, it not only saves time and money but 
also protects lives by preventing mechanical 
failures.
