Download or read book Evaluation of 6061 t6 to 2014 t6 and 6061 t6 to 6061 t6 Aluminum Alloy Welds written by R. Agricola and published by . This book was released on 1959 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: This weld-evaluation program was conducted by simulating the cap-to-skirt weld junction, the cap-toskirt T-weld junction, and the cap-to-outlet weld, and testing and examining these simulated welds for tensile tukon microhardness, and metallographic data. In addition special studies were made of welding under stress, mismatch of material thickness, and weld heat-affected zones. Confidence levels of 99.5%, 99.0%, and 95.0% for design application on fusion-, lap-, and T-welds are included. This report substantiates previous evidence that microcracks will not result from a 2014-T6 to 6061-T6 combination, provided the alloys are fusion- or T-welded and not lap-welded. This report also substantiates the fact that thickness mismatch in similar lap-welded metal junctions does not produce microcracks. Minimum ultimate tensile strength (UTS) data reveal that the use of thinner-than-anticipated dome material may be possible. Data on weld heat-affected zones prove that the heataffected zone of 6061-T6 is greater than that of 2014-T6 and furnish the land widths necessary to restrict heat flow during welding of fusion and lap welds.

Download or read book Weldability of High strength Aluminum Alloys written by Robert Melvin Evans and published by . This book was released on 1966 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: This memorandum describes the fusion-welding characteristics, mechanical properties, and stress-corrosion behavior of high-strength, weldable aluminum alloys. These are defined as alloys in which sound welds can be produced and in which at least 50 and 70 percent of the maximum base-metal strength can be retained in the as-welded and post-weld-treated conditions, respectively. Careful selection of joining method and filler metals as well as close control of joining-process parameters is necessary to produce high-strength aluminum weldments. Highest strengths and weld-joint efficiencies in high-strength weldable alloys are achieved with the use of postweld aging and/or mechanical treatments. The best combination of highest strengths and good welding characteristics is found in the 2000 and 7000 alloy series. As compared with the 2000 and 5000 alloy series, the 7000 alloy as a class suffer three major property disadvantages: (1) their tendency to be notch sensitive, (2) their tendency to exhibit low toughness at low temperatures, and (3) their much greater susceptibility to stress-corrosion cracking. Nonetheless, several relatively new 7000 series alloys have been developed which show reasonably good notch toughness to -423 F and which are considered competitive with the 2219 and 2014 alloys for cryogenic applications.

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.

Download or read book Dissimilar Metal Welding written by Pierpaolo Carlone and published by MDPI. This book was released on 2019-12-12 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: The combination of distinct materials is a key issue in modern industry, whereas the driving concept is to design parts with the right material in the right place. In this framework, a great deal of attention is directed towards dissimilar welding and joining technologies. In the automotive sector, for instance, the concept of “tailored blanks”, introduced in the last decade, has further highlighted the necessity to weld dissimilar materials. As far as the aeronautic field is concerned, most structures are built combining very different materials and alloys, in order to match lightweight and structural performance requirements. In this framework, the application of fusion welding techniques, namely, tungsten inert gas or laser welding, is quite challenging due to the difference in physical properties, in particular the melting point, between adjoining materials. On the other hand, solid-state welding methods, such as the friction stir welding as well as linear friction welding processes, have already proved to be capable of manufacturing sound Al-Cu, Al-Ti, Al-SS, and Al-Mg joints, to cite but a few. Recently, promising results have also been obtained using hybrid methods. Considering the novelty of the topic, many relevant issues are still open, and many research groups are continuously publishing valuable results. The aim of this book is to finalize the latest contributions on this topic.
