Title: The effects of water backing on SA106 Gr. B pipe welds

Abstract

In nuclear power plants, welding often must be performed on piping systems that contain water. This occurs when the system cannot be isolated due to the piping configuration, plant operating requirements or the failure of a component in the system. Water-backed welds are routinely made on austenitic stainless steels and are often preferred to prevent intergranular stress corrosion cracking (IGSCC). However, welding on mild steel piping with water backing presents significant concerns as to the integrity and serviceability of the welds. This paper discusses the results of testing that was performed on mild steel pipe to determine the fitness-for-service of water-backed shielded metal arc (SMA) weldments.

  • The results of reversed-cycle fatigue tests of ASTM A-155 Class I Gr. KC70 pipe weldments and base materials under various surface conditions and with artificial flaws are presented. These tests were carried out to provide additional bases for predicting the effect of weldment flaws upon fatigue strength. Fatigue specimens were made up from 2-in.-long ring sections of 18- in.-OD, 1.18-in.-thick seam-welded pipe which was rejected for fabrication into the NPR primary loop. Testing was accomplished with a special bending fatigue test machine composed of a 210 nifsegment of the ring specimen with masses located at each extremity excited at itsmore » natural frequency of approximately 50 cps by a shake table. Twenty-five specimens were modified with sharp V'' notches to 1/8-in. depth machined into the weld, heat affected zone, or base metal. Five specimens were made up with 3/16-in.-deep cracks in the form of lack of penetration'' weldments. Fatigue strength data from these specimens were compared with data from sound weld and base metal specimens having as- received'' and polished surfaces. Fatigue stresses ranged to 45,000 psi and fatigue lives to 3 x 10/sup 6/ cycles. The results showed the material to be relatively insenisitive to mechanical notches. The fatigue sensitivity of the material to the various flaw conditions was expressed in the form of a stress concentration or (when the elastic stress concentration factor could be computed) notch sensitivity factor.

    Dynamic fracture toughness tests were performed on materials which had been subjected to one of three long-time post weld type stress relief heat treatments: 48 hours at 1000/degree/F (538/degree/C), 24 hours at 1125/degree/F (607/degree/C), and 48 hours at 1125/degree/F (607/degree/C). Linear elastic K/sub Id/ results were obtained at low temperatures while J-integral techniques were utilized to evaluate dynamic fracture toughness over the transition and upper shelf temperature ranges. Tensile, Charpy impact, and drop weight nil-ductility transition tests as well as room temperature, air environment fatigue crack growth rate tests (SA508 Cl 2a only) were also performed. The fracture toughness ofmore » both materials exceeded the ASME specified minimum reference toughness K/sub IR/ curve. 17 refs.« less

    Metallurgical evaluation of pipe-to-pipe welds in large-diameter, Type 304 stainless-steel piping used to construct the moderator/coolant water systems for Savannah River Site reactors had demonstrated that small weld defects found in this 1950-vintage system do not compromise the integrity of the system. The weld defects were too small for detection by the preservice standard radiographic inspection, but were found through systematic ultrasonic testing and penetrant testing evaluations of piping that had been removed during upgrades to the piping system. The defects include lack of weld penetration, slag inclusions, and other weld metal discontinuities. These discontinuities typically did not propagate duringmore » more than 35 years of service. The defects examined were too small and isolated to degrade the mechanical properties of the pipe-to-pipe weldments and, therefore, did not compromise the integrity of the piping system.« less
