FAQ


High frequency asked question

01: How Does Aluminum_Copper Foil Welding Ultrasonic Metal Welder work?

Aluminum or copper foil to be joined are hold together between the ultrasonic horn and anvil, they experience ultrasonic vibrations of 20khz to 40khz depends upon application, 40khz is precision bonding of two layers of copper foil as better choose, vibration of the horn causes the aluminum or copper foil to scrub together (in shear) that remove surface contaminants to expose bare metal areas, the material’s atomic structures then co-mingle to create a strong, surface molecular, solid-state bond that is clean and has low electric resistance, these properties together make the process idea for electronic application and more, the most popular is electric wire bonding and battery anode and cathode multiple-layers Al and Cu Foil stack bonding

02: What strength is expected from materials joined ultrasonically?

Usually, the bond created is as strong or stronger than the parent material, for aluminum and copper foil seam sealing can have hermetic sealing effect

03: What metals can be joined ultrasonically?

Generally, non-ferrous metals: aluminum, silver, gold, copper, brass, nickel and alloys of these materials, applications include battery foil/tab welding, wire splicing, wire termination, spot welding, seam welding and copper tube sealing for the refrigeration industry

04: What about steel components?

Welding to iron, steel and stainless steel is not recommended because they are harder that non-ferrous metals, the surface structure are too dense and do not allow the transfer of the materials for consistent bonding, the parameters required would be more aggressive with heat build-up, resulting in increased tool wear, while bonding may occur, consistent weld strength is difficult to achieve

05: What about dissimilar materials such as aluminum to copper?

Aluminum_Copper Foil Welding Ultrasonic Metal Welder works well for dissimilar materials because the process is the same whether the materials are similar or not, examples include battery nickel, copper tab, aluminum foil welding, copper foil welding, silver-plated or copper stranded wire to nickel-plated copper or brass terminals, copper pads to aluminum heat sinks, and precious metal contacts to contact arms among others

06: What about plated parts?

It depends upon the plating, tin plating inhibits the bonding process, acting more like a lubricant, the tin heats up and may actually reflow, the parts slide over each other rather than rubbing against each other, heat builds up which has a negative effect, especially on wire strands, as they become brittle and usually break, silver and gold plating is different, these are mot compatible because they seem to move away from the weld surface or are able to be scrubbed through to get to the base metal, applications with these plating include stranded wire splicing and tipping, wire termination to plated terminals or lead frames

07: What are weld size and material thickness restrictions?

6mm square wire cross sectional bonding for 40khz and 20khz, bigger size must select 20khz, the material can be of any thickness on the anvil side of the weld as long as it can be held stationary either on the anvil or be clamping, on the horn side, material can be up to 3mm provided sufficient power is available from the controller

08: Can tooling be reworked for extended use?

Many times a horn or replaceable tip can be reworked (build-in the new knurling) one time, more if the rework allows the tool to remain to print or weight specification, stick anvils can build-in new knurling pattern as long as they can still be clamped in position in the tool support or clamping and hold the part as required or bear the shearing force during vibration scrubbing

09: Can the same tooling be used for different applications?

Most tooling is custom make for specific application, especially the fixture, the knurl patterns on the horn and anvil are specified according to material thickness and weld area requirements as well as part configuration, some tooling combination may be used for situation other than the original application, but may need modification

10: How much training necessitate operating a new machine?

Aluminum_Copper Foil Welding Ultrasonic Metal Welder is very easy to operate and do not require any certification, keepleader provides training when installing the machine, and application, training includes operations of the controls, how and when to change tooling, parameter setting and place multiple application setups in the present menu if needed
