The sonotrode (horn) is the general name of all kinds of ultrasonic launching terminals. Its function is to coupling the ultrasonic with working project. Because it works by ultrasonic transmitting, the horn certainly should work in the resonance condition, i.e. its periodic resonance frequency must match with the oscillator. What's more, the oscillation amplitude must be in averages, the end surface shape must be to the welding horn's Main characteristic:1.The range of frequency: 15KHz 100KHz2.Material: alloy steel, aluminum alloy, titanium alloy, stainless steel3.Hardness: MaxHRC62&omicron4.Working condition: solid,liquid, liquid metals and so on.5.Surface treatment: black oxide, polish, chromium galvanized
