This book was released on 2015-06-23 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: TIG welding is one of the important weld process for the fusion reactor components developement and fabrication.The welding of aluminium is most difficult due to its thermo physical properties like high thermal and electrical conductivity, low melting point and strength. In this, TIG welding parameters welding current and welding speed are used to weld. TIG welded joints are then heat treated by artificial aging and solution treatment to evaluate the influence of PWHT on mechanical properties of AA6061 joints. Tensile strength and impact strength of as TIG welded and heat treated joints is evaluated.

Available in PDF, EPUB and Kindle. Book excerpt: The welding of structural materials, such as aluminum alloys 6063, 6061 and 6005A, does have an adverse influence on the microstructure and mechanical properties at locations immediately adjacent to the weld. The influence of heat input, due to welding and artificial aging, was investigated on aluminum alloy extrusions of 6063, 6061 and 6005A. Uniaxial tensile tests, in conjunction with scanning electron microscopy observations, were done on the: (i) as-provided alloy in the natural temper, (ii) the as-provided alloy artificially aged, (iii) the as-welded alloy in the natural temper, and (iv) the as-welded alloy subject to heat treatment. The welding process used was gas metal arc (GMAW) with spray transfer at approximately 140-220 amps of current at 22-26 volts. The artificial aging used was a precipitation heat treatment for 6 hours at 360oF. The aluminum alloys of the 6XXX series contain magnesium (Mg) and silicone (Si) and are responsive to temperature. Optical microscopy observations revealed the influence of artificial aging to cause change in both size and shape of the second-phase particles present and distributed through the microstructure. The temperature and time of exposure to heat treatment did cause the second-phase particles to both precipitate and migrate through the microstructure resulting in an observable change in strength of the material. Uniaxial tensile tests were conducted for desired specimen thicknesses for sake of comparison. Section 6.4.2-2 of the 2010 Aluminum Design manual discusses provisions for mechanical properties of welded and artificially aged aluminum light poles, fabricated from aluminum alloy 6063 and 6005A. A basis for these provisions was the result of older round-robin testing programs [2, 3]. However, results of the studies were never placed in the open literature. Hence, the focus of this study was to determine the expected mechanical properties of welded and artificially aged 6063, 6061 and 6005A aluminum alloys and publish the results. Tensile tests revealed the welded aluminum alloy to have lower strength, both yield and ultimate tensile strength, when compared to the as-received un-welded counterpart. The impact of post-weld heat treatment on tensile properties and resultant fracture behavior is presented and briefly discussed in light of intrinsic microstructural effects and nature of loading.
Download or read book Springback Assessment and Compensation of Tailor Welded Blanks written by Ab Abdullah and published by CRC Press. This book was released on 2022-12-27 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: Focusing on techniques developed to evaluate the forming behaviour of tailor welded blanks (TWBs) in sheet metal manufacturing, this edited collection details compensation methods suited to mitigating the effects of springback. Making use of case studies and in-depth accounts of industry experience, this book gives a comprehensive overview of springback and provides essential solutions necessary to modern-day automotive engineers. Sheet metal forming is a major process within the automotive industry, with advancement of the technology including utilization of non-uniform sheet metal in order to produce light or strengthened body structures. This is critical in the reduction of vehicle weight in order to match increased consumer demand for better driving performance and improved fuel efficiency. Additionally, increasingly stringent international regulations regarding exhaust emissions require manufacturers to seek to lighten vehicles as much as possible. To aid engineers in optimizing lightweight designs, this comprehensive book covers topics by a variety of industry experts, including compensation by annealing, low-power welding, punch profile radius and tool-integrated springback measuring systems. It ends by looking at the future trends within the industry and the potential for further innovation within the field. This work will benefit car manufacturers and stamping plants that face springback issues within their production, particularly in the implementation of TWB production into existing facilities. It will also be of interest to students and researchers in automotive and aerospace engineering.

This book was released on 2018-02-27 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: Activated tungsten inert gas welding process involves a method of increasing penetration capability of the arc in TIG welding. This is achieved through the application of a thin coating of activated flux onto the joint surface prior to welding. This leads to strong joint. This paper deals with the study of microstructural and mechanical properties of aluminium alloy AA-6061 weld joints using A-TIG welding. During the experiment the welding current and gas flow rate are used as variable parameters and welding speed kept as constant. In this activated TIG welding process, there were five single component fluxes which are CdCl2, SiO2, MgO, Al2O3 and TiO2 used in the initial experiment to evaluate Welding current, Gas Flow Rate, Flux by joining plates by using A-TIG welds. Based on the higher penetration of weld bead, two single component fluxes SiO2 and TiO2 were selected for actual experiment. The values of optimum welding current and gas flow rate and flux was finding out from the experiment. Welding specimen were investigated using scanning electron microscope, vicker's micro hardness test and tensile strength. The SiO2 flux produced the most noticeable effect in terms of tensile strength and micro hardness.

This book was released on 2011-02 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: Friction Stir Welding (FSW) is known to result in a complex microstructural development, with features that remain unexplained, such as: the formation of the onion rings structure. Moreover, various microstructural factors have been suggested to control the strength in Al-Mg AA5xxx welds, without identifying their relative contribution. Furthermore, the influence of the basemetal microstructural parameters (e.g. grains, intermetallic particles, stored energy) on the microstructure-property development has not been previously investigated. These issues are addressed in the present study.
