INERTIA FRICTION WELDING PROCESS, PROCEDURE AND PERFORMANCE QUALIFICATION
Year: 1975
Abstract: This standard contains design requirements and design considerations for the use of inertia friction welding, requirements for certification of welding equipment, qualification of welding procedures, and qualification of operators using these procedures and equipment.
Type I. Weldments which have high stresses imposed on them or have severe fatigue requirements.
Class A. Designates a solid stock joint or a solid stock joint subject to heat treatment after welding. For such a weld joint, no unwelded area is permitted. An unwelded center area will be acceptable only if the unwelded area is removed by a subsequent fabrication process.
Class B. Designates a tubular configuration joint where no unwelded area is permitted.
Flash should be removed from Type I weldments. This type and its classes will be assigned to weldments in which failure could result in injury to personnel.
Type II. Weldments which have light to moderate service stresses imposed on them or have low fatigue requirements.
Class A. Designates a solid stock joint where center defects are acceptable. The acceptability of such defects shall be determined by the procuring activity, but in any case the unwelded area shall not represent more than 10% of the total weld cross sectional area.
Class B. Designates a joint involving a tubular configuration or a joint involving solid state components with nonessential metal removed from the center. Flash removal is not mandatory for Type II weldments. This type and classes will be assigned to weldments in which failure will not result in injury to personnel. Intended Use: The inertia welding process described herein is to be used for the joining of parts which have at least one member with configuration that can be rotated. Joints involving similar and dissimilar ferrous and non-ferrous alloys, including superalloys, may be assembled using this process. Weld configurations that may be welded using this process are bar to bar, bar to tube, bar to plate, tube to tube and tube to plate.
