Ultrasonic metal welding is the use of high frequency vibration wave transmitted to the two metal surfaces to be welded, in the case of pressure, so that the friction between two metal surfaces to form a fused ultrasonic welding equipment manufacturers molecules between the layers, which is advantageous in that fast , energy saving, high weld strength, good conductivity, no spark, close to cold working; drawback is that the weld metal is not too thick (generally less than or equal to 5mm), solder bit is not too large, need pressure. The two main parameters of ultrasonic waves: Frequency: F≥20KHz (in practice because the effect of ultrasonic welding equipment similar products, usually F≥15KHz also called ultrasonic sound waves); power density: p = transmitted power (W) / emission area (cm2), usually p≥0.3w / cm2. Propagating ultrasonic energy in a liquid to the surface of soil cleaning ultrasonic metal welding equipment, the principle can be used "cavitation" phenomena explained: When ultrasonic vibration sound waves propagating in the liquid pressure reaches an atmospheric pressure, the power density of 0.35 w / cm2, then the ultrasonic sound waves can reach the peak pressure vacuum or negative pressure, but in fact no negative pressure exists ultrasonic welding device, thus producing a large pressure in the liquid, the liquid molecules pull fragmented into a cavitation void nuclear. This is very close to empty the vacuum pressure in the ultrasonic reverse it reaches the maximum rupture produced a strong impact due to the rupture of the surface of the object hit the dirt down. This shock wave phenomenon by numerous small cavitation bubbles burst produced called "cavitation" phenomenon. Sound intensity is too small can not produce cavitation.
