SCOPE 1.1 FormThis specification covers an aluminum alloy
6、in the form of welding wire. 1.2 ApplicationThis wire has been used typically as filler metal for gas-metal-arc or gas-tungsten-arc welding of aluminum alloys of similar composition where the joint is capable of being heat treated to a strength level comparable to that of the parent metal, but usage
7、 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 document is
8、sue 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 (inside

13、ling, and cleaning are controlled to ensure continued conformance to composition requirements, and the facility employs procedures to ensure traceability of wire to the originally analyzed source. 3.2 ConditionAs drawn, in a temper and with a surface finish which will provide proper feeding of the w
14、ire in machine-welding equipment.3.3 Fabrication3.3.1 Butt welding is permissible provided both ends to be joined are identified by chemical 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 wel
15、ding equipment. 3.3.2 Drawing compounds, oxides, dirt, oil, and other foreign materials shall be removed by processes which will neither 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 an
16、d evenly during welding and shall produce acceptable welds. ARP1876 may be used to resolve disputes. 3.5 QualityWire, as received by purchaser, shall be uniform in quality and condition, sound, and free from foreign materials and from imperfections detrimental to welding operations, operation of wel
17、ding equipment, or properties of the deposited weld metal.3.6 Sizes and Tolerances Wire shall be supplied in the sizes and to the tolerances shown in 3.6.1 and 3.6.2.

QUALITY ASSURANCE PROVISIONS 4.1 Responsibility for Inspection The vendor of wire shall supply all s
21、amples for vendors tests and shall be responsible for the performance of all required tests. Purchaser reserves the right to sample and to perform any confirmatory testing deemed necessary to ensure that the wire conforms to specified requirements. 4.2 Classification of Tests 4.2.1 Acceptance Tests
22、Composition (3.1), sizes and tolerances (3.6), and alloy verification (5.2) are acceptance tests and shall be performed on each inspection lot. 4.2.2 Periodic Tests Weldability (3.4) is a periodic test and shall be performed at a frequency selected by the vendor unless frequency of testing is specif
23、ied by purchaser. 4.3 Sampling and Testing Shall be in accordance with AMS2355. 4.4 Reports The vendor of wire shall furnish with each shipment a report stating that the wire conforms to the composition and other technical requirements.
