The Hybrid Diffusion Welding Machine by Haifei represents a technological leap in solid-state joining. Unlike traditional thermal press welding, our hybrid system combines MFDC Inverter heating with Precision Servo-Hydraulic pressure, enabling atomic-level diffusion at lower temperatures and shorter cycle times.
This process is specifically engineered for high-performance Copper Busbars, Liquid Cooling Plates, and EV Battery Connectors, ensuring zero porosity and maximum electrical conductivity.

Key Advantages
Enhanced Bonding Efficiency
Hybrid technology accelerates diffusion, reducing cycle time vs. traditional methods.
01
Broader Material Range
Effectively joins for copper
02
Superior Joint Integrity
Eliminates pores/defects via combined pressure (hydraulic/electric), heat, and surface activation.
03
Energy & Cost Savings
Lower temperature/pressure requirements than conventional diffusion welding.
04
Smart Process Control
IoT-enabled monitoring with real-time adjustments for temperature (500–1300°C), pressure (10–100MPa), and dwell time.
05
How It Works
Surface Prep
Ultra-clean interfaces ensure optimal atomic diffusion.
Hybrid Activation
Heat (resistance) + pressure (hydraulic and Pneumatic)
Diffusion Phase
Atoms migrate across the joint under controlled conditions, forming a seamless bond.

Everything You Need to Know
Can it weld dissimilar metals like Copper to Aluminum?
Yes, our hybrid system can be calibrated with specific transition layers to manage the Intermetallic Compound (IMC) growth between Cu and Al.
What is the maximum welding area supported?
Standard platforms support up to $400 \times 600\text{ mm}$, but we offer customized vacuum chambers and electrode sizes for larger heat exchangers.
Does the joint require post-weld machining?
Because of our precision mold design, the "flash" or deformation is minimal, often eliminating the need for CNC milling after welding.
