5、 (AZ91E)(Composition similar to UNS M11919)RATIONALEAMS4398 has been reaffirmed to comply with the SAE five-year review policy.1. SCOPE1.1 Form This specification covers a magnesium alloy in the form of welding wire. 1.2 Application This wire has been used typically as filler metal for gas-metal-arc

6、 and gas-tungsten-arc welding of magnesium alloys with aluminum as a significant alloying element (particularly those parts requiring consistently high-quality joints), but usage is not limited to such applications. 2. APPLICABLE DOCUMENTSThe issue of the following documents in effect on the date of

7、 the purchase order form 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 issue is specified. When the referenced document has been cancelled and no superseding document has been specified, the last p

8、ublished 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 USA and Canada) or 724-776-4970 (outside USA), www.sae.org.AMS2355 Quality Assurance, Sampling and Testing, Aluminum Alloys

TECHNICAL REQUIREMENTS 3.1 Composition Shall conform to the percentages by weight as shown in Table 1, determined in accordance with AMS2355: TABLE 1 - COMPOSITION Element min maxAluminum 8.1 9.3Zinc 0.40 1.0Manganese 0.17 0.35Iron (See 3.1.1) - 0.005 Silicon - 0.30Copper - 0.030Nickel

11、 - 0.0010Other Elements, Each (3.1.2) - 0.01 Magnesium remainder 3.1.1 If iron exceeds 0.005, iron to manganese ratio shall not exceed 0.032, determined using Equation 1. Example calculation: 0.006 wt % Fe = 0.030, which is less than 0.032 0.20 wt % Mn (Eq.1) 3.1.2 Determination not required for rou

12、tine acceptance. 3.1.3 Chemical analysis 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 a

13、nalyzed ingot. 3.2 Condition Wire for cut lengths shall be extruded and for spooled wire shall be extruded and sized. 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 station. The butt w

14、eld 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 substances harmful to we

15、lding operations. SAE INTERNATIONAL AMS4398 Page 2 of 5_3.4 Properties Wire shall conform to the following requirements: 3.4.1 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 recei

16、ved by purchaser, shall be uniform in quality and condition, sound, and free from foreign materials and 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

17、olerances shown in 3.6.1 and 3.6.2. 3.6.1 Diameter Shall conform to the tolerances shown in Table 2.

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 th

20、e right to sample and to perform any confirmatory testing deemed necessary to ensure that the wire conforms to specified requirements. SAE INTERNATIONAL AMS4398 Page 3 of 5_4.2 Classification of Tests 4.2.1 Acceptance Tests Composition (3.1) and sizes and tolerances (3.6) are acceptance tests and sh

21、all be performed on each lot. 4.2.2 Periodic Tests Weldability (3.3.1) is a periodic 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 s

22、hall furnish with each shipment a report stating that the wire conforms to the chemical composition and other technical requirements of this specification. This report shall include the purchase order number, lot number, AMS4398, nominal size, and quantity. 4.5 Resampling and Retesting Shall be in a

23、ccordance with AMS2355. 5. PREPARATION FOR DELIVERY 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

24、not contain wire from more than one heat of alloy. 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 restric

25、tion caused by overlapping or wedging. 5.4 Wire from 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 s

26、pool for alloy verification. 5.5 Packaging and Marking 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 author

27、ized by purchaser, will be subject to rejection. SAE INTERNATIONAL AMS4398 Page 4 of 5_8.
