This specification contains the requirements for friction stir welding (FSW) of aluminum aerospace hardware.The requirements include design of welded joints, qualification of procedures and operators, fabrication and inspection. The FSW methods covered by this specification are conventional FSW, retractable probe FSW, and self-reacting FSW.

This document recommends standards for joining, repair, maintenance, inspection of rail welds, and related rail components. For the purposes of this document, rails include railroad rails, crane rails, guard rails, electrical contact rails, girder rails, and retarder rails. Classification of rails is based on the American Railway Engineering and Maintenance-of-Way Association (AREMA) specifications governing the

1.1.1 This specification provides requirements for the design and manufacture of welded joints of hydraulic cylinders.When specfed in the purchasing documents, compliance with all the requirements shall be required. This specification does not apply to the manufacture of welded tubing used for hydraulic cylinders which is covered under ASTM and other recognized specifcations. This specification

This specification establishes minimum acceptable requirements for weld joint detail and fabrication by welding of rotating elements in new equipment. This specification also applies to the modification or repair by welding of rotating elements in existing equipment. Equipment types covered by this specification include, but are not limited to: crushers, fans, impellers, centrifugal impellers, kilns,
