Welding Tools
Robotic Welding Tools (TIG, Laser) for Joint Operations
Robotic welding tools are end-effector assemblies comprising a vacuum-modified tungsten inert gas torch, a fiber laser head, and a filler-wire feeder used for joining and repairing metal components. Operating at 5,000 W with a total mass of 20 kg, these tools execute precision laser welds and structural TIG joints governed by AWS D17.1 spacecraft welding standards. Although the lunar vacuum naturally facilitates welding by eliminating the need for shielding gas in select processes, operations require automated robotic tool changes and long-life laser sources designed to sustain a 10,000-hour mean time between failures across a 15-year operational lifespan.
