The butt weld shall not interfere with uniform, uninterrupted feeding of the wire in machine welding equipment.3.3.2 Drawing compounds, oxides, dirt, oil, and other foreign materials shall be removed by cleaning processes which will ne
17、ither result in pitting nor cause gas absorption by the wire or deposition of substances harmful to welding operations.3.4 Weldability: Melted wire shall flow smoothly and evenly during welding and shall produce acceptable welds. ARP1876 may be used to resolve disputes.3.5 Quality: Wire, as received
18、 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 sizes and to th
