17、capable of distinguishing the alloy from all other alloys processed in the facility, 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 welding.3.3.3 In-process annealing, if required, between cold rollin
18、g or drawing operations, shall be performed in vacuum or protective atmospheres to ensure freedom from surface oxidation and absorption of other extraneous elements.3.3.4 Residual elements, drawing compounds, oxides, dirt, oil, dissolved gasses and other foreign materials picked up during wire proce
19、ssing that can adversely affect the welding characteristics, the operation of the equipment, or the properties of the weld metal, shall be removed by cleaning processes that will neither result in pitting nor cause gas absorption by the wire or deposition of substances harmful to welding operations.
20、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.3.4.2 Spooled Wire: Shall conform to 3.4.2.1 and 3.4.2.2.3.4.2.1 Cast: Wire, wound
21、 on standard 12-inch (305-mm) diameter spools, shall have imparted to it a curvature such that a specimen sufficient in length to form one loop with a 1-inch (25-mm) overlap, when cut from the spool and laid on a flat surface, shall form a circle 15 to 50 inches (381 to 1270 mm) in diameter.3.4.2.2
22、Helix: The specimen on which cast was determined, when laid on a flat surface and measured between adjacent turns, shall show a vertical separation not greater than 1 inch (25 mm).SAE INTERNATIONAL AMS5774E Page 3 of 6_ 3.5 Quality: Wire, as received by purchaser, shall be uniform in quality and con
23、dition, 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 3.6.2.3.6.1 Diamet
24、er: Shall be as shown in Table 2.3.6.2 Length: Cut lengths shall be furnished in 18, 27, or 36-inch (457, 686, or 914-mm) lengths, as ordered, and shall not vary more than +0, -0.5 inch (-13 mm) from the length ordered.4. QUALITY ASSURANCE PROVISIONS: 4 .1 Responsibility for Inspection: The vendor o
