In this study, AA6061 and AA7075 aluminum alloys were joined with CMT welding. The effect of welding parameters...

...You Sung Han; Kyehyung Lee; Myoung-Soo Han; Hyunchil Chang; Kanghyouk Choi; Seyoung Im Welding is one of the most important joining processes, and the effect of welding residual stresses in a structure has a great deal of influence on its quality. In spite of such a key interest, the analysis...

...S. K. Panda; J. Li; V. H. Baltazar Hernandez; Y. Zhou; F. Goodwin Use of multiple advanced high strength steel sheets for fabrication of tailor welded blanks (TWBs) is one of the current interests for automotive and steel industries as it reduces manufacturing cost and weight of the vehicle...

...S. Chiozzi; V. Dattoma; F. Panella This work concerns single crystal Ni-based superalloy welded through the capacitor discharge welding (CDW) process. The static and fatigue behavior of CMSX-4 type single crystal alloy has been analyzed, performing mechanical tests on square specimens in order...

...P. Edwards; M. Ramulu An experimental study was conducted to identify acceptable welding parameters for friction stir welding Ti-6Al-4V butt joints, ranging from 3 mm to 12 mm in thickness. The primary parameters of interest were the spindle speed and feed rate. Welds were produced using spindle...

... is to process dual phase sheet steel through a tube making operation with electrical resistance welding. In the new processing method, a ferrite/pearlite sheet steel is formed into a tube, which is then normalized, induction heated to an intercritical temperature, quenched, and tempered, producing a dual phase...

...Y. H. Moon; D. I. Hyun; C. J. Van Tyne In cathode ray tubes, a tension is imposed into the shadow mask during manufacturing to avoid slight variations in the position due to in service temperatures or deformation. Initially, tension is imparted to the shadow mask after it is welded...

...G. Wang; M. E. Barkey A theoretical model for the estimation of fatigue crack length of tensile-shear spot welded specimen is developed which incorporates the natural frequency and mode variation. The model is based on the concept that the propagation of cracks causes a release of strain energy...

... corrosion cracking (SCC) is a primary concern in the design of these canisters because tensile residual stresses will be left behind by the closure weld. Alloy 22 is a nickel-based material that is particularly resistant to corrosion; however, there is a chance that stress corrosion cracking could develop...

... the influence of dynamic loads is of great importance as well. However, the influence of a corrosive environment and/or a welded condition on the fatigue properties of nautical aluminum alloys has been studied only superficially. In the present paper the influence of a seawater environment in combination...

...Rui Wu; Rolf Sandstro¨m; Facredin Seitisleam With modern welding methods, satisfactory microstructures in 9%CrMoV (P91) steel can be obtained with a modest variation in hardness and prior austenite grain size. However, there is always a risk that significant deviations in the properties can...

Khanna An incremental and thermal-electro-mechanical coupled finite element model has been presented in this study for predicting residual stress distribution in a spot welded steel joint. Approximate temperature dependent material properties, including physical and mechanical...

...M. A. Sutton; A. P. Reynolds; D.-Q. Wang; C. R. Hubbard Three-dimensional residual stress mapping of an aluminum 2024-T3 arcan specimen, butt-welded by the friction stir technique, was performed by neutron diffraction. Results indicate that the residual stress distribution profiles across the weld...
