Results and Discussions

In industries, there is a high need for the fault detection in the materials. Prior detection of failures in the machines will prevent the machine from sudden failure.

Experiments are performed on a number of different materials such as copper, steel, aluminium etc. Fault is created in some of the materials aartificially by making a cut in the material and some materials have been tested for natural faults in it.

Materials in which fault has been created artificially and tested using ultrasonic thickness measurement kit.

1. A steel block

2. A copper block

3. An aluminium block.

Materials which have been tested for fault using ultrasonic thickness measurement kit

1. A pipe mate of mild steel.

2. A bearing.

3. A mechanical equipment of casting steel.

4. A surface of unknown material.

Materials in which fault has been created artificially is tested using the ultrasonic measurement by calculating the distance measured by the Ultrasonic Thickness Gauge in which the speed of sound in the material has been inputted and fault is been detected by measuring the distance of the fault from one end of the material.

Fig 1: Experimental setup for measuring the distance of fault using Ultrasonic Thickness Gauge in Steel, Copper and Aluminium.

There are some materials which can be tested in the laboratory for the detection of fault such as bearing, an aluminium pipe, a handle and a surface of unknown material.

Fig 2: Measurement of the thickness of bearing made up of mild steel can also be calculated using ultrasonic thickness gauge.

Fig 3: Measurement of the thickness of a hollow made up of galvanize steel can also be calculated using ultrasonic thickness gauge and it can be checked using digital vernier calliper.

Fig 4: Measurement of the thickness of a unknown handle made up of galvanize steel can also be calculated using ultrasonic.

Fig 5: Measurement of the thickness of a unknown surface is being calculated using ultrasonic.
