Laser Welding Glove Box System

Designed specifically for materials and processes that cannot be welded in ambient air, suffer from poor weld quality, or generate toxic by-products when welded in a conventional atmosphere.

The system integrates the laser source (fiber / disk laser), galvo scanning head, worktable, CCD coaxial vision positioning system, and process monitoring modules (e.g. PLD) wholly or partially inside a glovebox, thereby completely isolating the weld zone from the ambient atmosphere and preventing oxygen (O₂), nitrogen (N₂) and water vapour (H₂O) from reacting with the high-temperature weld pool.

By eliminating hydrogen generated from water vapour dissociation, the system fundamentally prevents hydrogen embrittlement and delayed cracking in high-strength materials such as aluminium and titanium alloys. The chamber can be filled not only with inert gases (e.g. Ar, He), but also with reactive or mixed process gases as required by the application.

Fumes, spatter and particulates produced during laser welding are fully confined within the enclosure. Toxic welding fumes are captured inside the chamber and discharged only after purification by a dedicated exhaust-gas treatment system. The chamber itself functions as a primary laser safety enclosure, preventing laser radiation from escaping and ensuring operator safety.
