These recommended practices present descriptions of electron beam welding equipment and procedures for welding a wide range of metals and thicknesses. The appropriate terms, definitions, and safety considerations are presented in detail. Information is included on designing for electron beam welding (EBW), welding dissimilar metals and thicknesses, fixturing, specifications, and operator training and qualifications.

Highly technical and detailed descriptions of metallurgy and the physics of the EBW process, though important to the engineer and scientist, were considered beyond the scope of this publication. Related processes such as EB cutting, EB heat-treating, and EB curing, though similar in nature and procedure, were also considered beyond the scope of this document and are not included.

This standard makes use of both the International System of Units (SI) and U.S. Customary Units. The latter are shown within parentheses or in appropriate columns in tables and figures. The measurements may not be exact equivalents; therefore, each system shall be used independently.
