Presentation Transcript

  1. Ultrasonic welding is an industrial technique whereby high frequency ultrasonic acoustic vibrations are locally applied to work pieces being held together under pressure to create a solid state weld Introduction

  2. Why US Welding • 1) Ultrasonic assembly uses ultrasonic vibratory energy which is transmitted through the parts to melt and bond thermoplastic materials And joining thin sheet gauge metals and other lightweight materials • 2) This technique is fast, efficient, non contaminating and requires no consumables • 3) In ultrasonic welding, there are no connective bolts, nails, soldering materials, or adhesives necessary to bind the materials together

  3. Principle • In ultrasonic welding, frictional heat produced by the ultrasonic waves and force is used for the joining process. Ultrasonic waves (15 to 60 kHz) are transferred to the material under pressure with a sonometer. Welding times are lower than 3 s. The welding can proceed with or without the application of external heat
