SCOPE 1.1 FormThis specification covers an aluminum alloy in the form of welding wire. 1.2 ApplicationThis wire has been us
6、ed typically as filler metal for gas-metal-arc or gas-tungsten-arc welding of heavy sections of aluminum alloys of similar composition to produce joints having inherently low dilution ratio of base-metal to weld-metal, and where the weldment may require solution and/or precipitation heat treatment,
7、but usage is not limited to such applications.2. APPLICABLE DOCUMENTS The issue of the following documents in effect on the date of the purchase order forms a part of this specification to the extent specified herein. The supplier may work to a subsequent revision of a document unless a specific doc
8、ument issue is specified. When the referenced document has been cancelled and no superseding document has been specified, the last published issue of that document shall apply. 2.1 SAE Publications Available from SAE International, 400 Commonwealth Drive, Warrendale, PA 15096-0001, Tel: 877-606-7323

13、der 3.1.1 Chemical analysis of initial ingot, bar, or rod stock before drawing is acceptable provided the processes used for drawing or rolling, annealing, and cleaning are controlled to ensure continued conformance to chemical composition requirements, and the facility employs procedures to ensure
14、traceability of wire to the originally analyzed source. 3.2 Condition As drawn, in a temper and with a surface finish which will provide proper feeding of the wire in machine welding equipment.3.3 Fabrication3.3.1 Butt welding is permissible provided both ends to be joined are identified by chemical
15、 analysis or the repair is made at the wire processing station. The butt weld shall not interfere with uniform, uninterrupted feeding of the wire in machine welding equipment. 3.3.2 Drawing compounds, oxides, dirt, oil, and other foreign materials shall be removed by cleaning processes which will ne
16、ither result in pitting nor cause gas absorption by the wire or deposition of substances harmful to welding operations.3.4 Weldability Melted wire shall flow smoothly and evenly during welding and shall produce acceptable welds. ARP1876 may be used to resolve disputes. 3.5 QualityWire, as received b
17、y purchaser, shall be uniform in quality and condition, sound, and free from foreign materials and from imperfections detrimental to welding operations, operation of welding equipment, or properties of the deposited weld metal.3.6 Sizes and Tolerances Wire shall be supplied in the sizes and to the t
18、olerances shown in 3.6.1 and 3.6.2. 3.6.1 Diameter Shall be shown in Table 2.
