Laser Welding Vacuum Glove Box (customized)

The box structure is customized according to the customer's requirements, in conjunction with the operation of the welding machine, equipped with a display touch screen, tool storage drawers, and a cooling system for the welding machine. The glove box is equipped with an efficient, high-performance, and high-quality gas purification system that automatically absorbs water and oxygen molecules, providing an inert atmosphere for purifying O ₂ and H ₂ O, and providing an ideal atmosphere space for welding processes;

Structure composition and principle

The system includes a sealed enclosure, a set of (large and small) transition chambers that can be evacuated, a rotary vane vacuum pump, and a circulation system integrated with a microcontroller operation panel. The equipped inert gas purification system is equipped with a set of purification columns (fully automatic and renewable) and fans, which are used to purify and maintain the atmosphere inside the glove box, so as to always maintain an environmental atmosphere of H2O&O2 ≤ 0.1PPM inside the box, meeting your experimental needs;
