19、e equipment, or the properties of the weld metal, 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 Properties: Wire shall conform to the following requirements:3.4.1 Weldabil
20、ity: 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 on standard 12-inch (305-mm) diameter spools, shall have imparted to it a curv
21、ature 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 Helix: The specimen on which cast was determined, when laid on a flat surface a
22、nd measured between adjacent turns, shall show a vertical separation not greater than 1 inch (25 mm).SAE INTERNATIONAL AMS5789D Page 4 of 6 3.5 Quality: Wire, as received by purchaser, shall be uniform in quality and condition, sound, and free from foreign materials and from imperfections detrimenta
