This book was released on 1988 with total page 179 pages. Available in PDF, EPUB and Kindle. Book excerpt: Multi-kilowatt CO2 lasers are increasingly being used for welding applications due to their capability of producing deep penetration welds at high welding speeds. Although most metals are being successfully welded, laser welding of aluminum alloys is proving to be difficult. Combination of high thermal diffusivity and optical reflectivity to CO2 laser radiation causes difficulty in coupling the laser energy to the material. Much higher laser intensities are required to ensure coupling and to form the keyhole, than to maintain the keyhole and obtain smooth fusion, as absorption of laser energy improves dramatically with the keyhole formation. Laser welds in aluminum alloys contain extensive porosity, and excessive vaporization of alloying elements occurs from the fusion zone. The welds have severe undercuts and large discontinuous cavities on the bead surface. A more precise control of the weld heat input and a better understanding of the influence of process parameters and the alloying content on the weld characteristics is required to improve the laser weldability of aluminum alloys. Keywords: Aluminum alloy welding, Carbon Dioxide laser, Welding, Numerical modeling, Weld defects. (MJM).
Download or read book Welding and Joining of Aerospace Materials written by Mahesh Chaturvedi and published by Elsevier. This book was released on 2011-12-19 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: Welding and joining techniques play an essential role in both the manufacture and in-service repair of aerospace structures and components, and these techniques become more advanced as new, complex materials are developed. Welding and joining of aerospace materials provides an in-depth review of different techniques for joining metallic and non-metallic aerospace materials.Part one opens with a chapter on recently developed welding techniques for aerospace materials. The next few chapters focus on different types of welding such as inertia friction, laser and hybrid laser-arc welding. The final chapter in part one discusses the important issue of heat affected zone cracking in welded superalloys. Part two covers other joining techniques, including chapters on riveting, composite-to-metal bonding, diffusion bonding and recent improvements in bonding metals. Part two concludes with a chapter focusing on the use of high-temperature brazing in aerospace engineering. Finally, an appendix to the book covers the important issue of linear friction welding.With its distinguished editor and international team of contributors, Welding and joining of aerospace materials is an essential reference for engineers and designers in the aerospace, materials and welding and joining industries, as well as companies and other organisations operating in these sectors and all those with an academic research interest in the subject. - Provides an in-depth review of different techniques for joining metallic and non-metallic aerospace materials - Discusses the important issue of heat affected zone cracking in welded superalloys - Covers many joining techniques, including riveting, composite-to-metal bonding and diffusion bonding

This book was released on 2018-07-06 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aluminum-lithium (Al-Li) alloys near net shape extrusions are being evaluated for potential application in launch vehicle structures. The objective of this study was to determine tensile and fracture properties, corrosion resistance, and weldability of integrally stiffened panels of Al-Cu-Li alloy 2090 in the T8 temper. The microstructure was pre-dominantly unrecrystallized. Texture analyses revealed the presence of fiber components in the stiffeners and a combination of fiber and rolling components in the skin. Variations in grain morphology and texture through the extruded cross section were correlated with the tensile, fracture, and corrosion behavior. Tensile strengths at room and cryogenic temperatures of the 2090 extrusions were similar to other 2090 product forms and were higher than 2219-T87, the primary structural material in the Space Shuttle external tank; however, ductilities were lower. The fracture resistance of the 2090 extrusion was lower than 2219-T87 plate at room temperature. At cryogenic temperatures, tensile ductility and fracture behavior of the 2090 extrusion were similar to other 2090 product forms but were lower than 2219-T87 plate. The exfoliation and stress corrosion resistance of the 2090 extrusion compared favorably with the characteristics of other 2090 product forms. The weldability and weldment properties of the extrusions were similar to 2090 and 2219 plates. Birt, M. J. and Domack, M. S. and Hafley, R. A. and Pollock, W. D. Langley Research Center...
