Product Description
Haifei ultrasonic spot welding machines utilize advanced
high-frequency mechanical vibration technology and are specifically
designed for precision welding of non-ferrous metals (such as
copper, aluminum, and nickel). This equipment achieves
instantaneous "cold welding" by generating intermolecular friction
and fusion at the contact surface using ultrasonic energy. Typical
applications include flexible connections for new energy vehicle
battery packs, welding of large-section wire harnesses and
terminals, and the assembly of aerospace electronic components.
Core advantages
1.Superior Welding Performance
Solder joints exhibit excellent conductivity, with resistivity
approaching zero or lower, effectively reducing equipment heat
generation and improving electrical efficiency.
2.Green and Low-Cost
Requires no solder, flux, or shielding gas; the welding process is
spark-free, smoke-free, and odorless, representing a truly clean
processing technology.
3.Intelligent Control System
An integrated microcomputer control system precisely adjusts
welding energy, time, and pressure, ensuring extremely high
consistency and repeatability in large-scale production.
4.Protection of Sensitive Components
Utilizing a cold welding process, the heat-affected zone is
minimal, effectively preventing carbonization of wire harness
insulation or damage to precision electronic components caused by
high temperatures.
5.High-Efficiency Production
The welding time for a single solder joint is only 0.5-1.5 seconds,
significantly shortening production cycles and adapting to
high-intensity industrial production lines.
Typical application areas
1.New Energy Vehicles
Power battery module busbars, high-voltage wiring harnesses, and
terminals.
2.Power Electronics
Large-section wire connections in frequency converters and
distribution cabinets.
3.Consumer Electronics
Tiny contacts in mobile phones and other electronic products where
conventional soldering is not feasible.
4.Medical and Aerospace
Precision instrument components requiring stringent solder purity
and stability.

FAQ
Q:What is the difference between ultrasonic welding and traditional
electric welding?
A:Ultrasonic welding is a "cold weld" process that uses
high-frequency vibration rather than high heat or melting,
preserving the original physical properties of the metal.
Q:Which materials can this machine weld?
A:It is primarily used for non-ferrous metals such as copper,
aluminum, nickel, gold, and silver, especially where high
electrical conductivity is required.
Q:How is the electrical conductivity after welding?
A:The conductivity is exceptional; the joint’s resistivity is
virtually identical to the base material, making it the preferred
solution for EV battery connections.
Q:Does the welding process require flux or filler?
A:No. It is a purely physical joining process that requires no flux,
filler metals, or shielding gases, making it environmentally
friendly and cost-efficient.
Q:Is the machine difficult to operate?
A:Not at all. The system features intelligent presets for pressure
and time; once configured, operators can easily execute welds via a
footswitch or button.
Q:How fast is the welding cycle?
A:It is extremely efficient. A single weld point usually takes only
0.5 to 1.5 seconds, allowing for rapid integration into high-speed
production environments.
