Due to the increased capability of both government agencies and private companies, space missions have become far more complex. Many of these missions involve building large structures, such as the Lunar Gateway, large satellites, or what is necessary for Moon/Mars habitation. These structures are too large to be launched as a single payload, requiring in-space construction. The ability to weld these structures together while in space would allow for strong, airtight seals and easy construction of many new structures. We are working on cold-welding technology to enable the construction of structures in space.
