HFTD-600-Y Copper Diffusion Welding Machine
Product Overview
The HFTD-600-Y Copper Diffusion Welding Machine is engineered for
diffusion welding of flexible copper busbars, copper strips, and
other conductive components requiring stable, low-resistance
joints. This advanced system combines a four-column hydraulic
welding structure with medium-frequency power supply, controlled
heating, and programmable welding parameters.
Supporting copper-to-copper, copper-to-nickel, and
hard-copper-to-soft-copper bonding, the machine accommodates
workpiece thicknesses from 0.5 to 25 mm. With a maximum hydraulic
output pressure of 20 tons, 600 kVA medium-frequency welding
transformer, and welding current up to 60 kA at 100% duty cycle,
the HFTD-600-Y delivers exceptional performance for demanding
flexible busbar and high-current copper connection production.
How the HFTD-600-Y Copper Diffusion Welding Process Works
The machine precisely controls temperature, hydraulic pressure, and
welding time throughout the diffusion welding cycle. Unlike
conventional filler-metal connections, this process brings mating
metal surfaces together under controlled heat and pressure. For
copper components, this method produces conductive joints while
maintaining the precise geometry required for downstream assembly
processes.

Frequently Asked Questions
What products is the HFTD-600-Y mainly used for?
Primarily designed for diffusion welding of flexible copper busbars
and copper strips. The machine can also be configured for other
copper conductive assemblies after process evaluation.
Can the HFTD-600-Y weld different copper combinations?
Yes. The specified material combinations include copper-to-copper,
copper-to-nickel, and hard-copper-to-soft-copper.
How many welding programs can be stored?
The control system supports up to 64 programmable welding
schedules, allowing different products or process conditions to use
separate parameter settings.
Can the machine be connected to a robot or PLC?
Yes. Three-stage programmable I/O is provided for integration with
PLCs, robots, and other production automation systems.
Does the HFTD-600-Y require cooling water?
Yes. The equipment requires a circulating cooling-water system with
a flow rate of at least 150 L/min, inlet temperature no higher than
35°C, and specified filtration and water-quality conditions.
Can Haifei test our copper busbar before equipment selection?
Yes. For copper diffusion welding, providing drawings or samples
allows welding parameters and tooling requirements to be evaluated
before final equipment configuration.
