# English Translation 1. Industry Boom: Ultrasonic Welding Becomes Mainstream Harness Processing Technology, Market Grows 20% Annually Rising reliability requirements for wiring harnesses in new energy vehicles and smart home appliances have made ultrasonic welding gradually replace traditional crimping technology. Market research forecasts that the global ultrasonic welding equipment market for wiring harnesses will exceed 5 billion RMB in 2025, with an annual growth rate over 20%. Core advantages: ✅ High reliability: Welding strength is 30% higher than crimping with lower resistance, eliminating poor connection risks. ✅ Eco-friendly: Solder-free and pollution-free, compliant with EU RoHS 2.0 standards. ✅ Automatic compatibility: Easily integrated into smart production lines, raising processing efficiency by over 50%. Enterprise Updates: Schunk launched new ultrasonic welders supporting adaptive welding for wires ranging from 0.08mm² to 50mm². UHT cooperates with Toyota to develop fully-automatic welding lines for vehicle high-voltage harnesses. 2. Technological Breakthroughs: High-frequency Welding & Laser-assisted Solutions Put into Application ① High-frequency Ultrasonic Welding (above 40kHz) Applied to ultra-thin wires of 0.05mm², adopted by Huawei and Xiaomi smart wearable devices. Welding time shortened to 0.3 seconds, heat-affected zone reduced by 60%. ② Laser-Ultrasonic Composite Welding Tesla applies this technology to weld nickel busbars of 4680 battery cells, raising yield rate to 99.9%. The laser-acoustic welding equipment jointly developed by Han's Laser and CATL has achieved mass production. ③ On-site Quality Monitoring System Branson adopts AI visual inspection to real-timely detect pores and cracks on welding spots.
