SCOPE 1.1 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 an
6、d gas-tungsten-arc welding of magnesium alloys of similar composition, 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 suppli
7、er 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 published issue of that document shall apply. 2.1 SAE Publications Available from SAE Internation

11、0.01 Magnesium remainder 3.1.1 Other Rare Earths shall be principally Heavy Rare Earths (e.g., gadolinium, dysprosium, erbium, ytterbium) (See 8.2). 3.1.2 Determination not required for routine acceptance. 3.1.3 Chemical analysis of initial ingot, bar, or rod stock is acceptable provided the process
12、es 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 for cut lengths shall be extruded and for spooled wire shall be extruded and
13、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 station. The butt weld shall not interfere with uniform, uninterrupted feed
14、ing 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 welding operations. 3.4 Weldability Melted wire shall flow
15、 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 foreign materials and from imperfections detrimental to welding operations, ope
16、ration of welding equipment, or properties of the deposited weld metal.SAE INTERNATIONAL AMS4393 Page 2 of 4_3.6 Sizes and Tolerances Wire shall be supplied in the sizes and to the tolerances as 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
19、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 confirmatory testing deemed necessary to ensure that the wire conforms to spec
20、ified 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 periodic test and shall be performed at a frequency selected by the vendor un
21、less 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 composition and other technical requirements of this specification. This r
22、eport shall include the purchase order number, lot number, AMS44393, nominal size, and quantity. SAE INTERNATIONAL AMS4393 Page 3 of 4_4.5 Resampling and Retesting Shall be in accordance with AMS2355. 5. PREPARATION FOR DELIVERY 5.1 Wire shall be supplied on spools in one continuous length for machi
23、ne 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. 5.3 Wire furnished on spools shall be closely wound in layers but adjace
24、nt 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 from each spool or package of cut lengths shall be alloy verified by a meth
25、od 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 Marking Shall be in accordance with AMS2813. 6. ACKNOWLEDGMENT A vendor shal
26、l 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. 8. NOTES 8.1 A change bar (l) located in the left margin is for the conven
27、ience of the user in locating areas where technical revisions, not editorial changes, have been made to the previous issue of this document. An (R) symbol to the left of the document title indicates a complete revision of the document, including technical revisions. Change bars and (R) are not used
28、in original publications, nor in documents that contain editorial changes only. 8.2 Other Rare Earths are derived from the yttrium (Typically 80% yttrium, 20% other rare earths). 8.3 Terms used in AMS are clarified in ARP1917. 8.4 Dimensions and properties in inch/pound units and the Fahrenheit temp
29、eratures are primary; dimensions and properties in SI units and the Celsius temperatures are shown as the approximate equivalents of the primary units and are presented only for information. 8.5 Purchase documents should specify not less than the following: AMS4393Size and form (spools or cut lengths) of wire required Weight of spools required Quantity of wire required.
