NASA uses a Variable-Power Handheld Laser Torch for their welding in space operations and fixing things in orbit. I've got several questions about this system.
- Is this system currently available/in use on the ISS?
- According to the description it uses a "Fiber Laser". Does this mean the Laser module is separate and connected to the "torch" with a fiber optic tether?
What type of power requirements does this Laser have?
How do you weld with it? Do you hold the laser in one hand and feed in a stick of metal with the other? Does it automatically feed the welding metal like a MIG welder?
Can this torch be used in pressurized and pressurized environments?
- Are there any videos of it in use?
