Welding Gun
A welding gun is a tool used in space and astronautical engineering to join two metal pieces together by heating them to a melting point and allowing them to cool and solidify, creating a strong bond. The welding gun typically uses an electric arc or laser to generate the heat needed for the welding process. The gun is held by the operator and directed at the metal pieces to be joined, while a filler material may also be added to the joint to strengthen it further. Welding guns are commonly used in the construction and repair of spacecraft, satellites, and other space vehicles, as well as in the manufacturing of components for space exploration. They are also used in the maintenance and repair of space stations and other space infrastructure.
