14、 remainder 3.1.1 Chemical analysis of initial ingot, bar, or rod stock before drawing is acceptable provided the processes used for drawing or rolling, annealing, and cleaning, are controlled to ensure continued conformance to chemical composition requirements. 3.1.2 Check Analysis Composition varia
15、tions shall meet the applicable requirements of AMS2269. 3.2 Condition Cold worked, bright finished, in a temper and with a surface finish which will provide proper feeding of the wire in machine welding equipment. 3.3 Fabrication 3.3.1 Wire shall be formed from rod or bar descaled by a process whic
16、h does not affect the composition of the wire. Surface irregularities inherent with a forming process that does not tear the wire surfaces are acceptable provided the wire conforms to the tolerances of 3.6. SAE INTERNATIONAL AMS5786H Page 3 of 6 3.3.2 Butt welding is permissible only at diameters la
17、rger than final finished product size provided both ends to be joined are alloy verified using a method 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, uninterru
18、pted feeding of the wire in machine welding. 3.3.3 In-process annealing, if required, between cold rolling 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, draw
19、ing compounds, oxides, dirt, oil, dissolved gases, and other foreign materials 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 that will neither result
20、in pitting nor cause gas absorption by the wire or deposition of substances harmful to welding operations. 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 u
21、sed 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 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 s
22、pool and laid on a flat surface, shall form a circle 15 to 50 inches (381 to 1270 mm) in diameter. 3.4.2.2 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). 3.5 Quality W
23、ire, 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
24、 sizes and to the tolerances shown in 3.6.1 and 3.6.2. 3.6.1 Diameter Shall be as shown in Table 2.
