22、ches (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 Wire, as received by purchaser, shall be uniform in quality and c
23、ondition, 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 sizes and to the tolerances shown in Table 2. 3.6.1 Diameter Sh
