Hi all,
Are u interested to know about spark testing?
Spark testing is a method of determining the general classification of ferrous materials.
Normally it entails taking a piece of metal, usually scrap, and applying it to a grinding
wheel in order to observe the sparks emitted.
These sparks can be compared to a chart or to sparks from a known test sample
to determine the classification.
Spark testing also can be used to sort ferrous materials,establishing the difference
from one another by noting if the spark is the same or different.
Moreover, test samples do not have to be prepared in any way,
so often, a piece of scrap is used. The main disadvantage to spark testing
is its inability to identify a material positively; if positive identification is required,
chemical analysis must be used.
Spark testing is used because it is quick, easy, and inexpensive but for me best way to get UI comforts by thinking all ways of user side.
The spark comparison method also damages the material being tested.
But human spark test saves risk of that abnormal occurance.
