What is welding?.

What is Ultrasonic Welding?. Ultrasonic welding (USW) is a solid-state welding process that produces a weld by local application of high-frequency vibratory energy while the work pieces are held together under pressure ..

Methodology. In general, based on its component itself. Welding process starts from the power supply where it converts low voltage electricity to high frequency electrical energy and next the converter or transducer converts electrical energy to mechanical vibratory energy. Subsequently, the amplitude of the vibrations transmits them to the horn where it transmits vibratory energy to the parts. Sample was hold in place and pressure was applied during the welding and thus joints the parts. In other way of illustration, ultrasonic welding process starts by clamping the workpiece between the horn and anvil. Then, the horn vibrates and starts to produce heat which will automatically melt the contact surface consequently build up deformation layer. Finally weld area was performed and joined the workpiece together..

Step 1. Part in fixture The two metal parts that need to be assembled are placed together, one on the top of the other, in a supportive nest called a fixture (Anvil)..

Step 5. Hold time The clamping force is maintained for a predetermined amount of time to allow the parts to fuse as the melted metal cools and solidifies. This is known as hold time. Improved joint strength and hermetical sealing may be achieved by applying a higher force during the hold time. This is accomplished using dual pressure at various points in the hold time..

What is piezo?. The Discovery of Piezoelectricity Piezo as noted in all formal sources is a Greek root meaning pressure or push . It's combined with some other words to make new nouns and adjectives. For example a piezometer is a pressure meter; piezoresistor is an electronic component which changes its resistance when exposed to stress; and piezoelectric is an adjective describing a property of some special solid materials that can convert some of the energy from an applied pressure into electric charge. Piezoelectricity was first discovered in 1880 by two brothers and French scientists, Jacques and Pierre Curie . While experimenting with a variety of crystals, they discovered that applying mechanical pressure to specific crystals like quartz released an electrical charge. They called this the piezoelectric effect..
