 1, the principle 

 Ultrasonic metal welding is the use of high frequency vibration wave propagation to the two metal surfaces to be welded, in the case of pressure, friction between the two metal surfaces to form the fusion between the molecular layer, and its advantage is rapid, energy, fusion high strength, good conductivity, no spark, close to the cold working. 

 2, welding advantages: 

 3,1), welding material does not melt, no fragile metal properties. 

 2) After soldering, good conductivity and resistivity low or near zero. 

 3), low demand for welding metal surface, oxidation or plating can be welded. 

 4), welding time is short, without any flux, gas, solder. 

 5), no welding sparks, environmental safety. 

 3, ultrasonic metal welding applies to products: 

 1), nickel metal hydride battery nickel metal hydride battery nickel screen with nickel plate and nickel plate each melt each melt. . 

 2), lithium batteries, polymer batteries each piece melt copper and nickel, aluminum foil with each melt. . 

 3), each wire melting, forming a partial melt with the number of each. 

 4), were kind of wire and electronic components, contacts, connectors, each melt. 

 5), were kind of home appliances, automotive supplies a large heat sink, heat exchange fins, each honeycomb heart melt. 

 6), the electromagnetic switch, no fuse switch high current contacts, mutual dissimilar metal melt. 

 7), the metal tube end sealing, cutting can be water tight. 

 4, the amplitude parameters 

 Amplitude for the materials to be welded is a key parameter, the equivalent of ferrochrome temperature, the temperature will reach the weld is not on, the temperature is too high will cause the material burned or cause structural damage and intensity variation. Because every company selected a different transducer, transducer output amplitude are different, after adaptation of different ratios horn and welding head, welding head can be calibrated to meet the requirements of the amplitude of work, usually for can output amplitude 10-20μm, and 30μm working amplitude is generally around the horn and horn ratio and welding head with horn shape around the area ratio and other factors, such as the exponential shape for amplitude, a function type amplitude, ladder-type amplitude, etc., a great impact on the transformation ratio, before and after the area ratio is proportional to the total ratio. Your company use a different brand of welding machine, the easiest way is to have to work according to the proportion of size of production welding head, can guarantee the stability of the amplitude parameters.
