The Importance of Amplitude as a Core Parameter (Part 1)
Attention friends in ultrasonic welding! Amplitude is the key to achieving a good weld, just like the temperature of a soldering iron!
Insufficient temperature results in poor welding, while excessive temperature burns the material, damages the structure, and drastically reduces strength.
Transducers from different manufacturers have varying output amplitudes, typically 10–20 microns. However, the actual working amplitude required for welding is about 30 microns.
This is adjusted by the booster and horn, whose amplification ratio depends on their shape and front/rear area ratio.
Types such as exponential and stepped shapes have a significant influence: the larger the area ratio, the higher the amplification ratio.
When matching parts for different brands of welding machines, the simplest method is to proportionally replicate a working horn using the exact same material, which ensures stable and accurate amplitude.
