HFTD-350Y Busbar Expansion Joints Welding Machine Hydraulic Busbar Welding Machine
- The HFTD-350 Hydraulic Busbar Welding Machine is widely used in the power, chemical, and smelting industries, primarily producing busbar expansion joints and flexible conductive tape, which are in high demand.
- Diffusion time refers to the time the weldment remains at the welding temperature. Complete diffusion must occur within this time to achieve the required strength. If the diffusion time is too short, the joint will not achieve stable strength equal to that of the parent material. However, if the duration of high temperature and high pressure is too long, the joint quality will not be further improved. For certain welding parameters, a welding time of several minutes is sufficient.

our case
Case 1
Welding of Copper-Nickel Flexible Connections
A new energy battery enterprise needed to weld flexible connections composed of copper busbars and nickel sheets. Due to the significant difference in thermal expansion coefficients between copper and nickel, traditional welding was prone to cracking. By introducing the polymer diffusion welding machine and adopting interlayer design and graphite mold clamping technology, the following results were successfully achieved:
- Splash-free welding: No oxide layer at the interface, and the welding strength increased by 30%;
- Efficient production: A single device completes 320 welds per hour, with a yield rate of 99.5%.
Case 2
Automated Production of Copper Busbar Flexible Connections
The "Automatic Cutting and Welding Machine for Flexible Copper Busbars" launched by Wuxi Haifei integrates the full process of feeding, cutting, and welding, realizing:
- Full automation: One operator can manage 2-3 devices, and the efficiency is 4 times higher than that of traditional manual operations;
- Precise control: The temperature (±10℃) and pressure (80kN) are adjusted through the PLC system to ensure welding consistency.
