What Are The Advantages Of Ultrasound Compared To Laser Welding Machines And Ultrasonic Welding Machines?

Ultrasonic welding machines have advantages such as fast speed, energy-saving, high fusion strength, good conductivity, no spark, and near cold processing.
It can be used for welding of similar metals, as well as spot welding and multi-point short strip welding of single and thin non-ferrous metals (such as copper, silver, aluminum, and nickel). It can be widely used for welding of various shapes, such as connectors for fuse type lithium batteries.
Laser welding machine is a new welding method. Laser welding machines are mainly used for welding thin-walled materials and precision parts. It can complete spot welding, butt welding, lap welding, sealing welding, etc.
The advantages of laser technology are that welded parts do not require pressure, and the overall deformation is small, which can minimize the damage to the surface of the heat absorbing coating. However, laser welding can also affect the physical structure of the welded object, and the welding points are prone to fracture, with poor strength, which is particularly fatal for the cold and hot exchange caused by the day and night work of the flat plate collector.
The advantages of ultrasonic welding are that the welding material does not melt, the metal properties are not fragile, the welding time is short, the melting strength is high, and it is close to cold working; However, it will damage about 3% of the heat absorbing layer, and the welding metal should not be too thick (generally ≤ 5mm, which has become an advantage of welding flat solar heat absorbing panels). In addition, due to the fact that ultrasonic welding is a continuous non melting welding, the heat transfer efficiency is relatively good. Under the same working conditions, the efficiency of ultrasonic welding products is approximately the heat conduction efficiency of laser welding.
Ultrasonic welding machines are used for welding similar to metals, and can perform single point and multi-point short strip welding on thin materials of copper, silver, aluminum, and nickel non-ferrous metals. They can be widely used for welding shapes such as lithium battery ears.
The ultrasonic welding machine adopts electronic program control, with high power, high efficiency, automatic control, easy operation, built-in electronic protection circuit, safe use, stable and reliable operation. The welding parts have characteristics such as firm welding surface, high strength, subjective, and environmental protection.
The biggest advantage of ultrasonic welding is actually that the equipment price is much lower when all welding requirements are met.
