This specification provides the general welding requirements for welding aircraft and space hardware. It includes but is
not limited to the fusion welding of aluminum-based, nickel-based, iron-based, cobalt-based, magnesium-based, and ti-
tanium-based alloys using electric arc and high energy beam processes. There are requirements for welding design, per-
sonnel and procedure qualification, inspection, and acceptance criteria for aerospace, support and non-flight hardware.
Additional requirements cover repair welding of existing hardware. A commentary for the specification is included.
