Gantry Laser Welder with Zero-Deformation Welding for Extra-Long Seams and Helium Leak Test Standard Airtightness for Intelligent & Flexible Production

In the era of high-performance computing and new energy vehicles, thermal management is critical. Our Gantry Laser Welding Special Machine is engineered specifically to tackle the most demanding challenge in liquid cold plate manufacturing: achieving a flawless, continuous seal over extra-long seams. Unlike traditional methods, this system combines a long-stroke gantry architecture with precision laser control to ensure your cold plates meet the strictest helium leak test airtightness standards.

The core advantage of our gantry design is its ability to handle extra-long liquid cooling manifolds and cabinet-level headers without compromising structural integrity.

• Low Heat Input: Utilizing high-energy density laser beams, we minimize the heat-affected zone (HAZ < 0.1mm). This ensures "zero deformation" on thin-walled materials (0.8-2mm), preserving the precise geometry of internal flow channels.
• Uniform Seam Quality: The system guarantees consistent weld depth and width across meters of continuous welding, eliminating risks of leakage at any point along the seam.

Sealing reliability is non-negotiable. Our solution integrates a closed-loop quality control process designed to pass rigorous helium mass spectrometry leak detection.

• Defect-Free Bonding: Advanced beam oscillation technology effectively suppresses spatter and porosity, common defects in aluminum and copper welding.
• Process Validation: The welded seams are dense and robust, capable of withstanding high-pressure burst tests and meeting vacuum-tight requirements essential for EV battery packs and data center cooling systems.

Designed for mass production, the machine features an automated dual-station design and fast-change fixtures. It supports rapid switching between different cold plate specifications, making it ideal for both standardized mass production and flexible customization.
