ARP1876 may be used to resolve disputes. 3.5.3 Spooled Wire Shall conform to 3.5.3.1, 3.5.3. 2 and 3.5.3.3. SAE AMS5782G Page 4 of 7 3.5.3.1 Winding Filler metal i
23、n coils and on spools shall be wound 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
24、shall be fastened to avoid unwinding. The winding shall be level winding. 3.5.3.2 Cast Wire, wound on standard diameter spools as shown in Table 2 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 a
25、nd laid on a flat surface, shall form a circle (cast) within the limits shown in Table 2. 3.5.3.3 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 shown in Table 2.
