Frequently Asked Questions
What materials is the YN-D2012-G ultrasonic welding machine suitable for?
This machine is specifically designed for copper, aluminum, and copper-aluminum composite busbars, particularly ideal for solid-state welding of large cross-section conductive materials from 35-120mm², widely used in power busbars, energy storage busbars, and new energy vehicle connectors.
What are the advantages of the 12000W power compared to conventional models?
The 12000W high power provides stronger energy output, enabling rapid welding of large cross-section workpieces (e.g., 120mm² copper busbars), reducing welding time by over 30% while ensuring uniform weld point strength.
How does the equipment ensure welding consistency?
Through 20KHz high-frequency vibration and a digital amplitude adjustment system, real-time monitoring of welding energy output, combined with precision molds, ensures stable parameters for each weld point, suitable for mass production.
Is installation and commissioning service provided after purchase?
We offer comprehensive after-sales service, including equipment installation, operation training, and 24-hour technical support. Specific warranty policies (e.g., mold warranty period, core component warranty years) can be obtained from the sales team for detailed terms.
Can this equipment be used for dissimilar metal welding of aluminum and copper?
Yes. Ultrasonic welding uses the solid-state connection principle without melting the metal, making it particularly suitable for copper-aluminum dissimilar material welding, avoiding the brittle intermetallic compound issues common in traditional welding.
