A brief introduction to ultrasonic metal welding machine

Ultrasonic metal welding machine is a kind of metal welding. With this machine, the welding time is very short and the pressure used is relatively small. Its working principle is to transmit high-frequency vibration waves between the two metal surfaces to be welded, and then a certain pressure will be generated. Under such pressure, the surfaces of the two metals will produce a certain friction and then fuse the two molecular layers.

The ultrasonic metal welding machine has certain advantages. It can complete the work task relatively quickly when used, and the energy consumption is very small. The fusion strength is also very high, and its conductivity is very strong, so there is no need to consider the resistance too much, and there are not too many requirements for the surface of the welded metal. Whether it is oxidation or electroplating, it can be operated. When welding, the time used is very short, and when operating, there is no need to use some auxiliary items, so the cost and time of welding are reduced. There is no spark when working, and it can even be comparable to the processing in the cold state.

However, everything is not perfect, so it also has some shortcomings. For example, the metal parts it can weld are also limited. If it is too thick, it cannot be operated. When welding, the point position cannot be too large, otherwise it will affect the welding effect, and during the welding process, pressure is required to complete it.

The scope of application of ultrasonic metal welding machine is very wide, and it can be used in the welding of many items, such as melting aluminum foil and aluminum sheet, melting some wires, melting wires and other electronic devices, melting different types of metal sheets, melting various home appliances, melting the heat sink of large equipment, melting the tail of metal pipes, etc. So its contribution to us is still very large.

The ultrasonic metal welding machine has a very important working part, that is, its welding head. The design of the welding head is very critical, because it directly affects the overall quality of welding, so it needs to be paid attention to. When designing the welding head, it must be symmetrical. If the welding heads on both sides are uneven, it is very likely that the welding head will work unevenly, causing the welding head to overheat and even break.

Ultrasonic metal welding machines have a certain lifespan, and its service life is related to many factors, such as its materials and its process. The materials generally used are aluminum alloys and titanium alloys, because they must meet the requirements of metal flexibility, but the welding head must also have a certain wear resistance, so this brings certain difficulties to the selection of materials, because it is difficult to find metals that meet these two conditions at the same time. However, high-quality steel materials can solve this problem very well, so it has become a commonly used material.
