Core Technology & Products

Medium Frequency Spot and Projection Welder (ADB Series)
Addresses inconsistent nugget size and high spatter issues in traditional AC welding through precision control. The inverter frequency reaches 1000Hz, providing 20 times better current control accuracy than AC machines. Energy efficiency improvements reduce power grid demand by one-third compared to AC welders, with power factors ranging from 0.7 to 0.9. Features include 3-phase balanced power to minimize grid impact, HMI interface for real-time current and time monitoring with pressure and water flow alarms, and straight current waveforms ensuring stable nugget size with minimal spatter.

Capacitor Discharge Spot Projection Welding Machine (ADR Series)
Engineered for heat-sensitive parts and multi-point projection welding applications. The ultra-short discharging time of approximately 10ms prevents workpiece surface discoloration and thermal deformation. Energy output remains stable within 1% fluctuation regardless of power grid instability. Super-high current capacity reaches up to 200KJ for extremely large components, while requiring less than one-fifth the power capacity of AC welders.

Flash Butt Welding Machine (AUNS/AUVS Series)
Specialized for large-section metal parts and special steel alloys, achieving weld quality nearly identical to base metal for sections up to 20,000mm². The AUBS-630*2 New Energy Electric Axle Double-Head Pulsation Flash Butt Welder received "First Set of Major Technical Equipment" certification in 2024, marking a significant breakthrough as the first domestic double-head flash butt welding machine for truck axles developed in 2023.

Conclusion & Recommendations

The resistance welding machine supplier landscape offers diverse options tailored to specific manufacturing needs, from precision microelectronics joining to heavy industrial flash butt welding. When evaluating suppliers, manufacturers should prioritize three critical factors: technological capability alignment with specific materials and joint configurations, proven service infrastructure for installation and ongoing support, and digital integration compatibility with existing production systems.

For automotive and new energy applications involving high-strength steels, aluminum alloys, and dissimilar metal joining, prioritize suppliers with advanced medium-frequency inverter technology and comprehensive process databases. Electronics and medical device manufacturers should focus on suppliers offering micro-welding precision and clean-room compatible equipment. Companies implementing Industry 4.0 initiatives should evaluate suppliers based on data connectivity capabilities and quality traceability features.

Regardless of application, verify supplier credentials through industry certifications, patent portfolios, and quantifiable customer case studies. Request trial welding of actual production parts using your specific materials and thicknesses before final equipment selection. This practical validation ensures that theoretical capabilities translate into real-world production performance and long-term manufacturing success.
