The Metalworking and CNC Machine Tool Show (MWCS) is one of the core theme exhibitions of the China International Industry Fair and a premier international event in the machine tool sector. With its exceptional professionalism, cutting-edge technology showcases, extensive industry coverage, and international exchange platform, MWCS has not only set a benchmark in the domestic machine tool industry but also demonstrates unparalleled appeal and profound brand influence for overseas enterprises.
With the rapid development of artificial intelligence, high-performance computing, new energy vehicles, and energy storage systems, liquid cooling technology is spreading at an unprecedented speed. The year 2026 is regarded by the industry as the "Year of Liquid Cooling Explosion." Among the many cooling solutions, cold plate liquid cooling dominates the market due to its high maturity and ease of use, providing essential cooling support for AI computing centers, power batteries, and energy storage systems.
The Core Challenge: Manufacturing High-Performance Cold Plates
Cold plates, as the core components of heat exchange, must meet stringent requirements for high strength, high thermal conductivity, corrosion resistance, and absolute sealing. Consequently, they are primarily made of aluminum alloy and copper. However, the manufacturing of cold plates faces complex engineering reliability challenges:
Traditional welding processes struggle with high-reflectivity materials, thin-walled structures, and dense weld seams, often leading to excessive heat deformation, splatter, high porosity rates, and poor sealing. These issues become critical barriers to the large-scale mass production and performance upgrades of liquid cooling systems.
Welding Solutions for Liquid Cooling Plates
For more than a decade, the Huagang Laser Intelligent Equipment Group has been deeply involved in the field of laser intelligent manufacturing, accumulating a mature technology system and comprehensive product layout for welding liquid cooling core components. In the face of the diversified explosion node of the liquid cooling industry in 2026, Huagang provides not only equipment but also overall welding solutions for different material combinations.
Advanced Welding Technologies:
1.Ring Spot Welding Technology—The "Stability Expert" for Aluminum Alloy Welding
In the welding of aluminum alloy liquid cooling plates for new energy vehicles and energy storage, Huagang's ring spot technology demonstrates outstanding process stability. A typical case involves welding two 1+1mm aluminum alloy thin plates. Faced with challenges such as dense weld seams and stringent sealing requirements, Huagang uses a 2+2 ring dual-spot laser, with a precise 14/100μm inner/outer ring core diameter, effectively suppressing splatter and reducing porosity. The post-weld seams are aesthetically pleasing, free of internal pores, sealed without water leakage, and pass helium burst pressure tests up to level 8 standards, ensuring reliability during long-term service.
The post-weld seams exhibit a smooth and uniform appearance, with no internal porosity. The sealed joints effectively prevent water leakage, and they have successfully passed the helium burst pressure test at Level 8. This ensures that the liquid cooling plates maintain high reliability throughout prolonged service periods.
2.Red-Blue Laser Composite Welding Technology—The "Killer Weapon" for High-Reflectivity Materials
In welding high-performance computing liquid cooling plates made of copper and copper-stainless steel (dissimilar materials), the red-blue laser composite welding technology shows significant advantages. The blue light (absorption >47%) quickly melts the copper surface and expands the melt pool, while the red light achieves deep welding with high power density through a small core. The synergy of the two results in multiple process benefits:
Splatter Suppression: The blue light preheats and softens the melt pool, effectively suppressing welding splatter.
Porosity Reduction: The expanded melt pool delays solidification, allowing bubbles to escape and significantly reducing porosity.
Efficiency Enhancement: High-speed welding simultaneously increases copper's absorption of red light, achieving a "1+1>2" composite effect.
Additionally, this technology effectively addresses the challenges posed by significant physical differences in copper-stainless steel dissimilar materials, preventing brittle compound formation and ensuring joint strength and sealing reliability.
