6、n and heat resistant steel in the form of welding wire. 1.2 Application This wire has been used typically as bare wire filler metal for gas-tungsten-arc or gas-metal-arc welding of critical weldments of precipitation-hardenable, corrosion and heat resistant steels of similar composition where the we
7、ld area is required to have comparable strength and corrosion resistance to that of the parent metal, but usage is not limited to such applications. 2. APPLICABLE DOCUMENTS The issue of the following documents in effect on the date of the purchase order forms a part of this specification to the exte

20、rption of other extraneous elements. 3.4.4 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
21、, shall be removed by cleaning processes that will neither result in pitting nor cause gas absorption by the wire or deposition of substances harmful to welding operations. 3.4.4.1 If pickling is necessary to remove surface contamination or scaling, only a light pickle shall be used followed by vacu
22、um degassing. 3.5 Properties Wire shall conform to the following requirements: 3.5.1 Weldability Melted wire shall flow smoothly and evenly during welding and shall produce acceptable welds. ARP1876 may be used to resolve disputes. 3.5.2 Spooled Wire Shall conform to 3.5.2.1 and 3.5.2.2. 3.5.2.1 Cas
23、t Wire, wound on standard 12-inch (305-mm) diameter spools, 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 15 to 50 inches (381 to 1270 mm) in diam
24、eter. 3.5.2.2 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). 3.6 Quality Wire, as received by purchaser, shall be uniform in quality and condition, sound, and free fro
