1.1 Form:
This specification covers an aluminum alloy in the form of two types of welding wire.
1.2 Application:
This wire has been used typically as filler metal for gas-metal-arc and gas-tungsten-arc welding of aluminum alloy castings having similar composition and requiring, in the weld zone, response to heat treatment, properties, and corrosion resistance comparable to those of the castings. but usage is not limited to such applications.
1.3 Classification:
Wire supplied to this specificahon is classified as follows:
Type 1 As Extruded and Sized
Type 2 As Drawn
1.3.1 Unless a specific type is ordered, either type may be supplied.
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 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.
3.3 Fabrication:
3.3.1 Butt welding is permissible provided both ends to be joined are identified by chemical analysis o 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 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 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, 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 tolerances shown In 3.6.1 and 3.6.2.
136.1 Diameter:
3.6.1.1 Extruded Wire: Shall be as shown in Table 2.
4.4 Reports:
The vendor of wire shall furnish with each shipment a report stating that the wire conforms to the chemical composition and other technical requirements. This report shall include the purchase order number, inspection lot number, AMS 4245C, nominal size, type, and quantity.
4.5 Resampling and Retesting: Shall be in accordance with AMS 2355 or MAM 2355.
5. PREPARATION FOR DELIVERY:
5,1 Wire:
Wire shall be supplied either on spools in one continuous length for machine welding, or cut in lengths for manual welding as ordered. Wire on each spool or in each package of cut lengths shall be from the same heat of alloy.
5.1,1 Wire furnished on spools shall be closely wound in layers but adjacent turns within a layer need not be necessarily touching, 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.
5.2 Alloy Verification:
Wire on each spool or in each package of cut lengths shall be alloy verified by a method acceptable to purchaser. The alloy verification procedures of ARP4926 are recommended.
5.2.1 An 8-inch (203-mm) length of wire shall be made accessible at one end of each spool for alloy analysis, if required.
5.3 Identification:
Shall be by tab marking in accordance with AMS 2816 unless color coding in accordance with AMS
2819 or other method is specified by purchaser.
5.4 Packaging and Marking:
Shall be by standard method in accordance with AMS 2813 unless premium quality method in accordance with AMS 2814 or other method is specified by purchaser.
6. ACKNOWLEDGMENT:
A vendor shall mention this specification number and its revision letter 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.
