Purpose:

This specification defines the procedures and requirements for joining metals and alloys using the electron beam welding process.

Application:

These procedures are used typically for high quality, electron-beam welding of aerospace components, the failure of which could cause loss of the aerospace vehicle or one of its major components, loss of control, or significant injury to occupants of a manned aerospace vehicle, but usage is not limited to such applications.

The procedure covered by this specification is recommended for square groove and square scarf-butt joints for fatigue critical applications.:
