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.
What advantages does ultrasonic welding have compared with resistance welding and laser welding?
Ultrasonic welding advantages: ① Welding time 0.1~1.0 seconds (resistance welding 2~5 seconds), efficiency increased by 3~5 times; ② Welding temperature is lower than the metal melting point (about 40~60% of the melting point temperature), with no thermal deformation and no annealing; ③ Can weld copper-aluminum dissimilar metals (difficult with resistance welding); ④ No solder/flux, clean and environmentally friendly; ⑤ Low welding resistance (≤100μΩ), excellent conductivity; ⑥ Low energy consumption, only 30~50% of resistance welding.
Can ultrasonic welding replace resistance welding and screw connections?
Ultrasonic welding is an upgraded solution to resistance welding and screw connections: ① Replaces resistance welding: low welding temperature, does not damage the annealed state of copper wire, lower joint resistance (≤100μΩ vs resistance welding 200~500μΩ), more reliable in long-term operation; ② Replaces screw connections: no screws, nuts, washers or other accessories required, higher connection strength (tensile breaking force ≥80% of base material), no risk of screw loosening. Especially suitable for new energy batteries, high-voltage wire harnesses and other scenarios with extremely high requirements for connection reliability and conductivity. Replacement recommendation: for high-current connections, ultrasonic welding is preferred, with mechanical connections as auxiliary.
What air source and power supply conditions are required to use this ultrasonic welding machine?
Power supply: 220V/50Hz single-phase AC (Chinese mainland); Air source: compressed air, pressure 0.5~0.7MPa, flow ≥200L/min (varies by model), air source must be dry and oil-free (recommended to equip with a refrigerated dryer + three-stage filter). Recommended equipment working environment temperature 5~40℃, relative humidity 30~80%, no corrosive gases or dust.
Does the ultrasonic welding machine require preheating when started? Are welding parameter settings complicated?
The ultrasonic welding machine is ready to weld immediately after startup, requires no preheating, and completes self-check within 10 seconds to enter working status. Welding parameter settings are simple: set the three core parameters of welding power (10~100%), welding time (0.01~1.0s), and welding pressure (0.1~0.7MPa) via touch screen or keys. Yingna Technology equipment supports parameter recipe storage (maximum 100 recipes); when switching product models, they can be recalled with one key, with no need for repeated settings, especially suitable for multi-variety, small-batch production.
How is an ultrasonic welding machine installed and commissioned after purchase? How long does it take?
Yingna Technology provides full installation and commissioning services: ① Equipment performance testing and pre-commissioning of welding parameters are completed before delivery; ② A video of the equipment running is taken before shipment to confirm its status; ③ After the equipment arrives, engineers provide remote video guidance for installation (completed in 1~2 hours), including power connection, air connection, leveling, and trial operation; ④ On-site acceptance criteria: 50 consecutive welding spots, with appearance qualified, resistance qualified, and pull force qualified. Overseas customers can choose on-site installation and commissioning by engineers (extra charge, approximately 2~3 days to complete).
Is sample testing provided for first purchase? Is there a charge?
Yingna Technology provides free sample testing services: ① The customer sends welding samples and materials; ② The Yingna technical team selects suitable equipment and welding head according to material specifications; ③ Trial welding is performed and welding parameters are recorded; ④ The welded samples and welding parameter report are sent back. The sample testing cycle is usually 3~5 working days, and the cost is fully waived. After the sample test is qualified, mass production orders can use these parameters to achieve consistent production quality. When requesting sample testing, please clearly provide: material grade (copper/aluminum), wire diameter (mm²), number of layers, welding requirements (strength/resistance).
Does the ultrasonic welding machine support automation integration and PLC control?
Yes. Yingna Technology ultrasonic welding machines provide RS232/RS485 communication interfaces and support integration with PLCs, robots, and automated production lines. Integrable functions: start signal, alarm feedback, welding parameter feedback, and production counting. With automatic wire feeding machines, automatic cutting machines, and automatic inspection equipment, a fully automatic ultrasonic welding production line can be built, requiring manual labor only for loading and unloading. Yingna Technology provides technical support to assist with automation solution design and installation and commissioning.
