This thesis explores the concept of welding in a space environment with the use of automation. Since the amount of time astronauts can work outside a spacecraft is limited, future construction and repair tasks will likely be assisted by automation. It is also likely that remote space welding will be needed for the construction of large-scale space structures in earth orbit as well as for lunar and Martian ground-based structures. Due to the complex nature of the tasks to be accomplished, the equipment will probably not be fully autonomous but instead supervised by a human operator. The welding fabrication problem in space is examined in a broad sense including some of the considerations for designing a human supervisory remote welding system. The history of space welding processes is examined, as well as current research in the field. A task definition and functional analysis is provided to assist future designers in outlining typical operational sequences for such a remote welding system. Such analysis is important when deciding whether the human operator should perform certain tasks or if the operator should supervise the automated system while it performs the tasks.
