1.1 Purpose:
This specification defines the procedures and requirements for joining metals and alloys using the
electron beam welding process.
1.2 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.
1.2.1 The procedure covered by this specification is recommended for square groove and square
scarf-butt joints for fatigue critical applications.:strRefField
