AWS D14.6/D14.6M

This specification establishes minimum acceptable requirementsfor weld joint detail and fabrication by welding of rotatingelements in new equipment. This specification also applies to themodification or repair by welding of rotating elements in existingequipment. Equipment types covered by this specification include,but are not limited to: crushers, fans, impellers, centrifugalimpellers, kilns, pulpers, gears, sheaves, drive trains,crankshafts, flywheels, power transmission shafts, air movingdevices, blowers, and rotating elements of hydro electricgenerating equipment. The intent of this specification is notto include steam or combustion turbine rotors, blading, orcamshafts. This specification also applies to such products andprocedures that are agreed to by the Manufacturer, Fabricator, orRepair Organization and the Owner.

Requirements contained herein are not intended to nullify orvoid the requirements of any law or governmental agency regulationor other codes applied to components. Additional requirements maybe invoked by contract documents. The specification establishes theminimum acceptable practice at the time of its publication. It isnot intended to restrict new developments or in any way to inhibitadvances in the art and science of welding.

This specification is intended to promote the following:

(1) High quality construction and repair of welded rotatingelements of equipment;

(2) Adequate initial and sustained performance of weldedrotating elements of equipment;

(3) Personnel safety;

(4) Clear, concise fabrication practices that will be readilyunderstood by the Manufacturer, Fabricator, or Repair Organization,Fabricator, Owner, and user; and

(5) Conservation of human and material resources in thefabrication of welded rotating elements of equipment.

This specification makes use of both U.S. Customary Units andthe International System of Units (SI). These measurements may notbe exact equivalents; therefore each system must be usedindependently of the other without combining in any way. Thespecification with the designation D14.6 uses U.S. Customary Units.The specification D14.6M uses SI Units. The latter are shown inappropriate columns in tables or within brackets ([ ]) when used inthe text.

Safety and health issues and concerns are beyond the scope ofthis standard, and therefore are not fully addressed herein. Safetyand health information is available from other sources, including,but not limited to ANSI Z49.1, Safety in Welding, Cutting, andAllied Processes, and applicable federal and stateregulations.
