Cái Greenstone High-Power Vacuum Laser Welding R&D Platform is a large-format, high-precision system engineered for deep-penetration vacuum laser welding, process development, and application-level production verification. By performing welding inside a controlled negative-pressure (vacuum) environment, the platform improves laser energy utilization and stabilizes keyhole and molten pool behavior—helping to reduce porosity-related defects and enhance weld consistency, especially in demanding materials and thick-section joints.

Vacuum conditions can significantly influence melt flow mechanisms and pore formation behavior during welding. In practice, this means improved stability of the welding process and fewer gas-porosity defects—resulting in stronger, more reliable welds and better overall joint quality. With 10 kW / 30 kW power configurations available and a spacious 2500 × 2500 × 1500 mm working envelope, Greenstone supports large and complex structural components while maintaining precise motion control and repeatable positioning.

Designed for both process research và industrial implementation, this platform supports welding forming and repair of large, complex parts made from titanium alloys, aluminum alloys, high-temperature alloys, stainless steels, and carbon steels. It is well-suited for advanced manufacturing sectors such as aerospace, transportation, new energy, and nuclear-related industries, where weld integrity, deep penetration capability, and defect control are critical.
