Applications of Ultrasonic Wave

 Ultrasonic Drilling

Ultrasonics are used for making holes in very hard materials like glass, diamond etc. For this purpose, a suitable drilling tool bit is fixed at the end of a powerful ultrasonic generator.

Some slurry (a thin paste of carborundum powder and water) is made to flow between the bit and the plate in which the hole is to be made

Ultrasonic generator causes the tool bit to move up and down very quickly and the slurry particles below the bit just remove some material from the plate.

This process continues and a hole is drilled in the plate.

Ultrasonic welding

The properties of some metals change on heating and therefore, such metals cannot be welded by electric or gas welding.

In such cases, the metallic sheets are welded together at room temperature by using ultrasonic waves.

Ultrasonic soldering

Metals like aluminum cannot be directly soldered. However, it is possible to solder such metals by ultrasonic waves.

An ultrasonic soldering iron consists of an ultrasonic generator having a tip fixed at its end which can be heated by an electrical heating element.

The tip of the soldering iron melts solder on the aluminum and the ultrasonic vibrator removes the aluminum oxide layer.

The solder thus gets fastened to clear metal without any difficulty.

Ultrasonic cutting and machining

Ultrasonic waves are used for cutting and machining.

Ultrasonic cleaning

It is the cheapest technique employed for cleaning various parts of the machine, electronic assembles, armatures, watches etc., which cannot be easily cleaned by other methods. technique which stands for Sound Navigation and Ranging.

Its Uses ultrasonic for the detection and identification of underwater objects.

The method consists of sending a powerful beam of ultrasonics in the suspected direction in water.
