Mechanical and metallurgical data are given on specimens of Inconel plate and pipe after the various heating and forming operations involved in making of a fabricated pipe. The fabricated pipe meets the mechanical requirements of the Inconel plate Specification Sb-168 of the ASME Boiler and Pressure Vessel Code and the quality requirements of welded pipe stipulated in ASTM A358-56T specification for electric-fusion-welded austenitic chromium-nickel alloy steel pipe for high temperature service. The particular plate discussed was sensitive to the welding process used. Welding with coated electrodes and the tungsten-arc process produced sound welds while the heat-affected zone of the welds made by the gas-shielded-arc consumable-electrode process showed fissures. These fissures are associated with segregate regions in the base metal. (auth)
