Product Overview
The HFTD-150-Y Copper Busbar Welder is designed for diffusion
welding of conductive metal components such as copper busbars,
copper bars, copper-nickel connectors, and laminated copper foil
flexible connectors. It is widely used in new energy, power
equipment, energy storage, low-voltage electrical products, copper
busbar processing, and electrical connection manufacturing.
Copper has high electrical and thermal conductivity, which can make
conventional welding difficult. Common issues include fast heat
dissipation, unstable weld strength, poor bonding between layers,
and inconsistent electrical performance. The HFTD-150-Y uses
controlled heating, pressure, and welding parameters to create
reliable joints, helping customers improve weld strength,
electrical stability, and batch consistency.
Key Selling Points
Designed for Conductive Copper Components
The HFTD-150-Y is not a general-purpose metal welder. It is
developed for conductive parts such as copper busbars, copper bars,
laminated copper foil connectors, and copper-nickel sheets. For
conductive components used in new energy batteries, power systems,
energy storage equipment, and low-voltage electrical products, it
helps deliver more stable joint quality.
Suitable for Laminated Copper Foil Flexible Connectors
Laminated copper foil flexible connectors are usually made from
multiple thin copper foils. Welding requires careful control of
temperature, pressure, and interlayer bonding. The HFTD-150-Y is
suitable for welding laminated copper foil assemblies and helps
reduce weak bonding, delamination, local overheating, and uneven
joint quality.
Improves Electrical Stability of Copper Busbar Joints
Copper bars and copper busbars are commonly used for high-current
transmission. Customers care not only about weld strength, but also
contact resistance, temperature rise, and long-term reliability.
Diffusion welding forms a stable bond over a larger contact area,
helping reduce overheating and performance variation caused by poor
contact.
Supports Copper-Nickel Dissimilar Metal Joining
Copper-nickel joints are common in new energy battery connections,
electrical assemblies, and conductive structures. Since copper and
nickel differ in thermal conductivity, electrical conductivity, and
forming behavior, the welding process requires more precise
control. The HFTD-150-Y can be matched to different material
combinations, thicknesses, and weld areas.
Product Application Areas
New Energy Battery Connectors
Used for welding copper busbars, copper bars, copper-nickel
connecting sheets, and conductive connectors in battery modules.
For high-current connection areas, weld quality directly affects
electrical stability and long-term safety.
Conductive Parts for Energy Storage Systems
Energy storage systems often use copper busbar joints, flexible
connectors, and current-collecting conductive parts. The HFTD-150-Y
can be used for diffusion welding of these copper components,
helping improve joint strength and production consistency.
Copper Busbar Processing for Power Equipment
Suitable for welding copper busbars and copper bars used in
distribution cabinets, busbar systems, switchgear, and power
connection parts. A stable welded contact area helps reduce local
overheating during high-current operation.
Low-Voltage Electrical Products
Used for welding conductive terminals, contact components, and
copper alloy parts in low-voltage electrical products. Fixtures can
be customized according to part size and weld position to improve
positioning accuracy and welding stability.
Laminated Copper Foil Flexible Connector Manufacturing
Suitable for welding laminated copper foil flexible connectors,
flexible conductive parts, and battery flexible connectors.
Controlled temperature and pressure help improve bonding between
foil layers.
Copper-Nickel Composite Connectors
Suitable for copper-nickel sheets, copper-nickel conductive parts,
and dissimilar metal connectors used in new energy, battery
systems, electrical connections, and precision conductive
assemblies.
Product Advantages
Addresses Fast Heat Dissipation in Copper Welding
Copper conducts heat quickly, making it difficult for conventional
welding methods to keep heat concentrated in the weld area. The
HFTD-150-Y uses controlled heating and pressure to provide a more
stable joining process for copper bars, copper foils, and copper
busbars.
Improves Bonding Between Multiple Layers
When welding multiple copper foils or sheets, interlayer bonding
directly affects mechanical strength and electrical performance. By
combining pressure and heat input, the machine helps create more
uniform bonding and reduces local weak joints.
Suitable for High-Current Conductive Components
Copper busbars, copper bars, and flexible connectors are often used
for power transmission or battery connections. These parts require
low contact resistance and reliable welded joints. The HFTD-150-Y
helps create a stable contact area and improves reliability in
long-term electrical operation.
Reduces Quality Variation from Manual Operation
With set parameters, fixture positioning, and pressure control, the
machine standardizes the welding process. For customers producing
similar copper parts over the long term, it helps control batch
variation and reduce rework.
Supports Sample Testing and Mass Production
Before final purchase, customers can verify weld strength,
appearance, electrical performance, and process stability through
sample welding. The equipment solution can then be optimized around
production cycle time, loading method, inspection needs, and
factory layout.

FAQ
Q1. What copper parts is the HFTD-150-Y mainly used for?
A:The HFTD-150-Y is mainly used for diffusion welding of copper
busbars, copper bars, laminated copper foil flexible connectors,
copper-nickel connecting sheets, and conductive terminals. It is
commonly used in new energy, energy storage, power equipment, and
low-voltage electrical applications.
Q2. Is this machine suitable for laminated copper foil flexible
connectors?
A:Yes. Laminated copper foil welding requires stable pressure,
temperature, and interlayer bonding. The HFTD-150-Y uses controlled
heating and pressing to improve bonding quality between copper foil
layers and reduce weak joints or delamination.
Q3. Will welding affect the electrical performance of copper bars?
A:Copper bar applications usually focus on contact resistance and
heat generation during operation. Diffusion welding creates a
stable joint over a larger contact area, which helps maintain
electrical stability. Final performance should be confirmed through
sample welding and electrical testing.
Q4. Can this machine weld copper-nickel dissimilar metal parts?
A:Yes. It can be used for copper-nickel joining. Because copper and
nickel have different material properties, customers are advised to
provide samples, thickness, weld area, and strength requirements.
Haifei can perform process testing before confirming the equipment
