TECHNICAL REQUIREMENTS 3.1 Composition Shall conform to the percentages by weig

10、ht as shown in Table 1, determined in accordance with AMS2355: TABLE 1 - COMPOSITION Element min max SilverDidymium (Total Rare Earths) 3.1.1 Zirconium, total CopperNickelOther Elements, total Magnesium2.01.750.40-remainder3.02.51.00.100.010.303.1.1 Didymium consists of neodymium (not less than 70%

11、of the total) plus praseodymium, along with lesser amounts of other rare earth elements. Vendor shall analyze and report neodymium and praseodymium in order to determine composition for routine acceptance. When analyzed, the total of all rare earth elements shall not exceed 2.5%. 3.1.2 Chemical anal

12、ysis of initial ingot, bar, or rod stock is acceptable provided the processes used for manufacture and cleaning are controlled to ensure conformance to composition requirements, and the facility employs procedures to ensure traceability of wire to the originally analyzed ingot. 3.2 Condition Wire fo

13、r cut lengths shall be extruded and for spooled wire shall be extruded and sized. Drawn wire may be supplied if acceptable to purchaser. 3.3 Fabrication 3.3.1 Butt welding is permissible provided both ends to be joined are identified by chemical analysis or the repair is made at the wire processing

14、station. The butt weld shall not interfere with uniform, uninterrupted feeding of the wire in machine welding equipment. 3.3.2 Oxides, dirt, and extruding compounds shall be removed by cleaning processes which will neither result in pitting nor cause gas absorption by the wire or deposition of subst

15、ances 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 Quality Wire, as received by purchaser, shall be uniform in quality and condition, sound, and free from fore

16、ign materials and from imperfections detrimental to welding operations, operation of welding equipment, or properties of the deposited weld metal.SAE INTERNATIONAL AMS4394 Page 2 of 4_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. 3.6.1 D

QUALITY ASSURANCE PROVISIONS 4.1 Responsibility for Inspection The vendor of wire shall supply all samples for vendors tests and shall be responsible for the performance of all required tests. Purchaser reserves the right to sample and to perform any con

20、firmatory testing deemed necessary to ensure that the wire conforms to specified requirements. 4.2 Classification of Tests 4.2.1 Acceptance Tests Composition (3.1) and sizes and tolerances (3.6) are acceptance tests and shall be performed on each lot. 4.2.2 Periodic Tests Weldability (3.4.1) is a pe

21、riodic test and shall be performed at a frequency selected by the vendor unless frequency of testing is specified 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

22、 composition and other technical requirements of this specification. This report shall include the purchase order number, lot number, AMS4394, nominal size, and quantity. SAE INTERNATIONAL AMS4394 Page 3 of 4_4.5 Resampling and Retesting Shall be in accordance with AMS2355. 5. PREPARATION FOR DELIVE

23、RY 5.1 Wire shall be supplied on spools in one continuous length for machine welding or in cut lengths for manual welding, as ordered. 5.2 Wire on each spool shall be of one continuous length from the same heat of alloy. Packages of cut lengths shall not contain wire from more than one heat of alloy

24、. 5.3 Wire furnished on spools shall be closely wound in layers but adjacent turns within a layer need not necessarily be touching. Wire shall be wound so as to avoid producing kinks, waves, and sharp bends, and shall be free to unwind without restriction caused by overlapping or wedging. 5.4 Wire f

25、rom each spool or package of cut lengths shall be alloy verified by a method acceptable to purchaser. The alloy verification procedures of ARP4926 are recommended. 5.4.1 An 8-inch (203-mm) length of wire shall be made accessible at both ends of each spool for alloy verification. 5.5 Packaging and Ma

26、rking Shall be in accordance with AMS2813. 6. ACKNOWLEDGMENT A vendor shall mention this specification number in all quotations and when acknowledging purchase orders. 7. REJECTIONS Wire not conforming to this specification, or to modifications authorized by purchaser, will be subject to rejection.
