A military welder works on and off base, repairing and fabricating metal parts for equipment, vehicles, and structures. If deployed overseas, you work at a station or camp, and responsibilities include repairing tools, weapons, and vehicles as they come in from service. You use different types of tools and welders, servicing everything from pipes to girders. As part of the military, your duties take you abroad to different military installations, into potentially hostile environs. If you enlist in the Navy or Air Force, you may acquire skills specific to welding naval and air equipment.
