Ultrasonic metal parts welding is done using an acoustic assembly integrated into our machine.
The acoustic assembly consists of an ultrasound generator, a piezoelectric converter (or transducer), a booster, or amplitude modifier and a Sonotrode.
Our ultrasonic components are designed and manufactured in France.
This allows us to provide you with a range perfectly suited to your applications:

The materials that can be welded using ultrasound are: aluminium (Al), copper (Cu), nickel (Ni), silver (Ag) and gold (Au).
The thicknesses may be different (in the photo, the thicknesses vary from 0.05mm to 2mm)
Ultrasonic welding is widely used for lithium-ion battery assembly. It allows pre-welding and welding between the anode sheets (copper film) and the cathode (aluminium) contained in these batteries.
This process ensures rapid and efficient connection of electrodes, connectors and other battery components, reducing assembly time.
Moreover, it is a non-destructive process. It does not require filler material for the welding, thus avoiding the risks of contamination and problems linked to welding residues.
Ultrasonic welding is highly precise and reliable, ensuring high mechanical strength of the weld and long battery life.
As with lithium-ion batteries, ultrasonic welding can be used for the assembly of new sodium-ion batteries.
Sodium ion batteries are energy storage devices that use sodium as a charged ion for electron transfer. Ultrasonic welding can be used to assemble the components of these batteries, such as electrodes, current collectors and separators.
Ultrasonic welding avoids exposure of components to high temperatures, an advantage for heat-sensitive batteries.
In the automotive industry, ultrasonic welding is mainly used for the assembly of thermoplastic parts. But it also has applications in welding parts made from non-ferrous metals: cable harnesses, chrome components, electric car batteries, etc. It ensures high mechanical strength, lasting process stability, limited scrap and low exposure to heat.
It is also very practical for manufacturing lightweight parts, such as aluminium body panels, which require rapid and precise welding.
Ultrasonic welding has specific applications in the electronics sector. It allows to solder electronic components, such as sensors, switches, chips, printed circuits and cables. It provides fast, precise, high-quality and safe soldering, essential to ensure the reliability of electronic components.
In aerospace, ultrasonic welding is used to weld aluminium and titanium parts, such as fuselage components and engine parts. This welding process provides both high-precision and high-quality welds.
In the medical industry, ultrasonic welding is used to assemble medical components such as pipes, reservoirs and medical device housings. The soldering is clean and hygienic, which is essential for medical devices destined for use in sterile environments.
