Abstract

The influence of nickel-iron electrode properties and joint shapes on QT600-3 nodular iron joint strength and cracking was investigated using the Moire fringe method. The total displacement of these welded joints under uniaxial tension was obtained. It was found that the newly developed nickel-iron electrode improved the welded joint strength. The experimental results also showed that double-V joint strength was higher than single-V joint strength, whereas single-U joint strength was lower than single-V joint strength. Single-U joint fracture was in the partially mixed zone of the weld root and parallel to the fusion line. This could be attributed to the complex compositions and structures at the weld root.

Investigation of fracture mechanical behavior of nodular cast iron and welded joints with parent-material-like weld metal

Conference Baer, W; Pusch, G

The focus of the investigations was the determination of fracture mechanical characteristics and crack resistance curves of the J-Integral and CTOD concept by application of the partial unloading compliance technique and D.C. potential drop technique (four point bend) under static load. The results show a close correlation between crack initiation values as well as crack resistance curves and graphite morphology parameters determined by means of quantitative microstructural analysis where the influence of the matrix (distance of graphite particles) dominates the crack resistance and fracture performance of ferritic nodular cast iron under consideration of the notch effect of graphite particles.

The effect of iron dilution on strength of nickel/steel and Monel/steel welds

Technical Report Fout, S; Wamsley, S

The weld strength, as a function of iron content, for nickel/steel and Monel/steel welds was determined. Samples were prepared using a Gas Metal Arc (GMAW) automatic process to weld steel plate together with nickel or Monel to produce a range of iron contents typical of weld compositions. Tensile specimens of each iron content were tested to obtain strength and ductility measurements for that weld composition. Data indicate that at iron contents of less than 20% iron in a nickel/steel weld, the weld fails at the weld interface, due to a lack of fusion. Between 20% and 35% iron, the highestmore »« less
Influence of chromium on the mechanical properties and microstructure of weld metal from a high-strength SMA electrode

Journal Article Surian, E; Trotti, J; Cassanelli, A; ... - Welding Journal (Miami); (United States)

In the present work, the influence of Cr on mechanical properties and microstructure of weld metal from a high-strength SMA electrode is analyzed by considering 12 experimental low-alloy low-hydrogen iron powder AWS E10018, E11018, E12018-M type covered electrodes. These electrodes were manufactured to obtain in the weld deposits Cr contents ranging from 0 to 1.8%, with two different Mn levels for each Cr content, maintaining the amount of other elements at a fixed value. All-weld-metal specimens and production type single V-groove welds were mechanically tested in the as-welded and stress-relieved conditions, and a metallographic study was conducted. Chromium was foundmore »« less
Properties of welded joints of alloys in the system Ti--V, Ti--V--Al, and Ti--Zr--Al with high oxygen content (in Russian)

Journal Article Gurevich, S; Blashchuk, V; Onoprienko, L - Metalloved. Term. Obrab. Metal., no. 10, pp. 6-8

A study was made of the mechanical and corrosion properties of welded joints of the alloys AK1 (Ti + 2.5% V), AK2 (Ti + 2.5% V + 3% Al) and AK3(Ti + 5% Zr + 2% Al), containing 0.25 to 0.35% U. Rolled specimens 6 mm thick were studied. The plates were welded by an automatic single-pass argon-arc welding machine using infusable tungsten electrodes. It is shown that the strength, ductility, and corrosion resistance of the welded joints are quite close to the figures for the base metal. (JPRS)
Effects of residual stress on fatigue strength of small diameter welded pipe joint

Book Yamashita, Tetsuo; Hattori, Takahiro; Nomoto, Toshiharu; ...

A power plant consists of many welded components, therefore, it is essential in establishing the reliability of the power plant to maintain the reliability of all welded components. The fatigue failure caused by mechanical vibrations of small diameter welded joints, which is represented by socket welded joints, is one of the major causes of trouble for the welded parts of the power plant. Here, bending fatigue tests were conducted to investigate the fatigue strength of small diameter socket welded pipe joints. In the most cases of large diameter socket joints, a fatigue crack started from the root of the filletmore »« less
