15、 machine welding equipment.3.3 Fabrication3.3.1 Wire shall be formed from rod or bar descaled by a process which does not affect the composition of the wire. Surface irregularities inherent with a forming process that does not tear the wire surfaces are acceptable provided the wire conforms to the t
16、olerances of 3.6.SAE AMS5818C Page 3 of 63.3.2 Butt welding is permissible provided both ends to be joined are alloy verified using a method capable of distinguishing the alloy from all other alloys processed in the facility, or the repair is made at the wire processing station. The butt weld shall
17、not interfere with uniform, uninterrupted feeding of the wire in machine welding.3.3.3 In-process annealing, if required, between cold rolling or drawing operations, shall be performed in vacuum or protective atmospheres to ensure freedom from surface oxidation and absorption of other extraneous mat
18、erials.3.3.4 Residual elements, drawing compounds, oxides, dirt, oil, dissolved gasses, and other foreign materials picked up during wire processing that can adversely affect the welding characteristics, the operation of the equipment, or the properties of the weld metal, shall be removed by cleanin
19、g processes that will neither result in pitting nor cause gas adsorption by the wire or deposition of substances harmful to welding operations.3.4 PropertiesWire shall conform to the following requirements:3.4.1 WeldabilityMelted wire shall flow smoothly and evenly during welding and shall produce a
20、cceptable welds determined by a procedure agreed upon by purchaser and vendor. The referee method of ARP1876 may be used to resolve weldability disputes.3.4.2 Spooled WireShall conform to 3.4.2.1, 3.4.2.2, and 3.4.2.3.3.4.2.1 WindingFiller metal in coils and on spools shall be wound so that kinks, w
21、aves, 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 shall be fastened to avoid unwinding. The winding sha
22、ll be level winding.3.4.2.2 CastWire, 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 and laid on a flat surface, shall form a circle (cast) w
