27、e, shall form a circle 15 to 50 inches (381 to 1270 mm) in diameter. 3.4.3.2 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). SAE INTERNATIONAL AMS5825H Page 4 of 6 3.4.
28、3.3 Winding Filler metal in 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 c
29、an be located readily and shall be fastened to avoid unwinding. The winding on spools shall be level winding. 3.5 Quality Wire, as received by purchaser, shall be uniform in quality and condition, sound, and free from foreign materials and from imperfections detrimental to welding operations, operat
