Global Innovative Welding Technology Solves Heterogeneous Metal Welding Difficulties

Technological innovation continues to inject new vitality into the upgrading of the welding industry. The world’s first NCW nugget control resistance welding technology, independently developed by Chinese enterprises, made its official debut at the 2026 China Science and Technology Fair, making a key breakthrough in the global difficult problem of steel-aluminum heterogeneous welding. Different from traditional resistance welding processes, this innovative technology features strong welding adaptability, ultra-low energy consumption and full air-cooling operation, eliminating the need for complex water-cooling systems and effectively reducing equipment operation and maintenance costs.

After repeated verification and testing, the NCW technology has been successfully applied to core welding scenarios such as new energy vehicle battery trays, automobile body structures and energy storage cabinets. It effectively solves the problems of unstable welding quality, easy deformation and low yield in heterogeneous metal welding, providing a new efficient and energy-saving solution for lightweight manufacturing in the new energy automobile and energy storage industries, and further enhancing China’s global competitiveness in advanced welding process technology.
