14、drawing or rolling, annealing, and cleaning are controlled to ensure continued conformance to composition requirements, and the facility employs procedures to ensure traceability of wire to the originally analyzed source. 3.2 Condition Wire may be made by any method unless a specific method is speci

15、fied. Wire shall be in a temper and with a surface finish which will provide proper feeding of the wire in machine welding equipment. 3.3 Fabrication Butt welding is permissible only at diameters larger than final finished product provided both ends to be joined are alloy verified using a method cap

16、ably of distinguishing the alloy from all other alloys processed within 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 equipment. SAE INTERNATIONAL AMS4244C Page 3 of 6 3.3.1 Resi

17、dual elements, drawing compounds, oxides, dirt, oil, dissolved gases and other foreign material picked up during wire processing 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 which wi

18、ll 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 rec

19、eived 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. 3.5.1 Winding Filler metal in coils and on spools shall be wound

20、so that kinks, waves, sharp bends, overlapping, or wedging are not encountered, leaving the filler metal free to unwind without restriction. The outside end of the electrode (the end where welding is to begin) shall be identified so it can be located readily and shall be fastened to avoid unwinding.

21、 The winding shall be level winding. 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 Diameter 3.6.1.1 Extruded Wire Shall be as shown in Table 2: Table 2A - Sizes and diameter tolerances, inch/pound units Form Nominal Diameter Inch T
