Скачать или смотреть Copper braids and copper busbar welding done by MFDC Spot welder

This video demonstrates copper braids and copper busbar welding performed using a MFDC (Medium Frequency Direct Current) spot welding machine, delivering a stable, low-resistance, and high-strength electrical connection for demanding industrial and new energy applications.

Welding copper braids to solid copper busbars is a critical process in applications where high current transmission, vibration resistance, and flexible connectivity are required. This type of joint is widely used in EV battery systems, energy storage systems (ESS), power distribution units (PDU), inverters, transformers, and industrial electrical equipment.

⚙️ Challenges in Copper Braid to Busbar Welding

Copper welding presents unique challenges due to:

Extremely high thermal and electrical conductivity

Rapid heat dissipation

Risk of oxidation during welding

Difficulty in achieving uniform bonding

Requirement for very low and stable electrical resistance

Traditional welding methods often struggle to provide consistent quality and reliable electrical performance when joining flexible copper braids to rigid copper busbars.

🔥 Why Use MFDC Spot Welding for Copper?

MFDC spot welding technology provides precise and fast current control, making it suitable for copper joining applications:

High peak current with accurate timing

Stable DC output for controlled heat input

Reduced spatter and surface damage

Strong metallurgical bonding

Excellent repeatability in batch production

The MFDC spot welder ensures uniform heat distribution at the joint interface, allowing the copper braid strands to bond securely with the copper busbar while maintaining excellent electrical conductivity.
