Control - is to check the process parameters or product compliance with requirements and regulations.
1. Visual control
Visual control is called
inspection of the object that is carried out by inspector with the naked eye or
with the use of simple optical devices: mirrors and magnifying glasses.
By visual inspection, operator must detect with the naked eye defect such as a
crack or corrosion point of 0.1 mm or more.
Mirrors are used to inspect inaccessible places. Their main function is to
change the angle of view. Mirrors with variable angle are very comfortable.
Magnifiers are used to increase the resolution of the eye, i.e. allow us to
consider the finer details of the object of control. Nowadays for exploring
inaccessible places, video endoscopes are used, allowing you to explore the
inner surfaces of the objects to be inspected.
2. Measuring control
The task of measuring control is establishing compliance with the standards and the numerical values of monitored parameters. Elements of measuring control may be present in any method of nondestructive and destructive testing.
