What is Vacuum Laser Welding
A molecular-level fusion process conducted in controlled vacuum environments (10⁻³~10⁻⁶Pa), where high-energy laser beams achieve metallic bonding free from atmospheric interference. This breakthrough technology transcends the physical limitations of conventional welding, delivering ultimate sealing solutions for mission-critical applications.
Precision Vacuum Generation System
Our 3-tier vacuum architecture redefines welding environment control. By integrating mechanical pumping, molecular extraction, and ionic purification technologies, we achieve surgical-grade vacuum environments ranging from 10⁻¹ Pa to 10⁻⁶ Pa. This modular system intelligently switches between turbo molecular pumps (for rapid gas evacuation) and sputter ion pumps (for ultra-clean maintenance), ensuring optimal vacuum states tailored to specific material requirements.

Benefits of Laser Welding in Vacuum
- An increase of over double the welding depth than in air
- Parallel-sided seams with reduced nailhead
- Increase process stability due to significantly reduced and stable plasma plume
- Reduction of workpiece contamination by spattering and vaporisation
- Higher-quality, pore-free weld seams
- Low operating costs due to efficient solid-state laser
- Welding process without inert gas
- No requirement for x-ray shielding
- Suitable for magnetic materials
