Superior Weld Quality Meets Cleanroom Conditions

Vacuum Laser Beam Welding (VLBW) combines the precision of laser welding with the contamination-free environment of a vacuum chamber. This hybrid approach eliminates oxidation, provides deep penetration, and significantly enhances metallurgical quality by preventing the formation of pores or inclusions.

Key Benefits of VLBW:

• Oxidation-Free Welding: Perfect for reactive and high-purity metals.
• Deeper Penetration: Enhanced weld depth in thick components.
• Minimal Heat-Affected Zone (HAZ): Ensures material properties remain intact.
• Improved Weld Strength & Appearance: Seamless results without post-processing.

• High-Power Laser Integration: Fibre lasers (1-20 kW) for various thicknesses.
• Modular Vacuum Chambers: Custom-built or standardised enclosures.
• 5-Axis CNC Handling: For flexible and complex geometries.
• Advanced Vision & AI Monitoring: Real-time weld quality assurance.
• User-Friendly Interface: Remote control and recipe-based workflows.

Aerospace & Space Research

Joining Lightweight and High-Strength Alloys with Zero Oxidation In aerospace applications, components are often made of lightweight, high-strength materials like titanium, Inconel, and aluminium alloys. VLBW ensures pore-free, crack-free joints in these reactive metals, which are susceptible to oxidation and hydrogen embrittlement under conventional welding.

• Hermetic sealing of sensor housings and fuel system components
• Structural joining of engine casings, turbine blades, and load-bearing parts
• Vacuum-tight welds for satellite and launch vehicle components
• Repair and refurbishment of thin-walled, high-value aerospace assemblies

Nuclear & Clean Energy

Vacuum-Based Precision Welding for Radiation-Exposed and High-Purity Environments The nuclear sector demands leak-proof and high-reliability welds in radiation-tolerant alloys. Vacuum laser welding provides a contamination-free process suitable for joining materials used in radioactive or high-temperature service, including zirconium alloys and stainless steels.

• Fabrication of encapsulated nuclear fuel assemblies
• Welding of pressure vessels, radiation shields, and test chambers
• Vacuum sealing of instrumentation for nuclear fusion and fission facilities
• Cleanroom-level welding for hydrogen and helium containment vessels

Medical Devices & Surgical Instrumentation

Cleanroom-Compatible Welding for Biocompatible Metals VLBW is ideal for manufacturing surgical-grade and implantable medical devices made from stainless steel, titanium, cobalt-chrome, and nitinol. The vacuum environment prevents oxidation and eliminates contamination risks, ensuring compliance with ISO 13485 and FDA standards.

• Sealing of implantable electronic devices like pacemakers and neurostimulators
• Welded enclosures for minimally invasive surgical instruments
• Assembly of high-precision tools for robotic surgery systems
• Leak-proof joins in drug delivery capsules and diagnostic probes

Semiconductor & Photonics Manufacturing

Submicron Accuracy and Contamination-Free Joints for Optoelectronic Devices Semiconductor manufacturing requires joining miniature, delicate components with precise heat control. VLBW ensures distortion-free welding with tight thermal zones, critical in preventing warping or delamination in multilayer electronics.

• Micro-welding of metal-glass or metal-ceramic sensor packages
• Void-free encapsulation of photonic sensors and MEMS devices
• Joining of temperature-sensitive substrates and micro-bonding pads
• Laser hermetic sealing for VCSELs, TO can packages, and fibre optic connectors
