Book excerpt: This report supplies information on joining processes applicable to titanium and its alloys in sheet metal applications, primarily related directly to airframe construction. Although the material presented here does not cover all titanium joining processes, and omits such processes as plasma-arc, submerged-arc, electroslag, flash, and high-frequency resistance welding, the data presented cover materials up to 2-inches thick in some cases and the report should be useful to anyone seeking titanium joining information. The joining processes covered fall into five categories: welding, brazing, metallurgical bonding (diffusion and deformation bonding), adhesive bonding, and mechanical fastening. The fusion welding processes that are discussed in detail include gas tungsten arc, gas metal arc, arc spot, and electron beam. The resistance processes give extended coverage are spot, roll spot, and seam welding. (Author).

This book was released on 2015 with total page 413 pages. Available in PDF, EPUB and Kindle. Book excerpt: Titanium alloys have turned strategically important in aerospace applications due to their high strength to weight ratio, corrosion resistance, and good strength sustainability at high temperatures. The joining of lightweight materials such as titanium alloys in aerospace industries offer two main benefits of near net shape manufacturing and of reduction in buy to fly ratio. Among the various joining methods, Diffusion Bonding and Friction Stir Welding (FSW) can be combined with superplastic forming, therefore, have been widely accepted technique to join titanium alloys to produce complex sheet structures with reduced weight and fabrication costs compared to mechanically fastened structures. Both the processes are mainly optimized for titanium alloy, Ti-6Al-4V, to produce defect free sheets of it. The other titanium alloys such as Ti-6242 and Ti-54MFG offer advantages of high temperature sustainability and better machinability over Ti-6Al-4V. The joining of titanium alloys with different properties can improve the utilization of titanium alloys and increase the functional properties of joints. However, a very limited research has been conducted on joining techniques with dissimilar titanium alloys. Therefore, the current study examines the processes with dissimilar titanium alloys to broaden the application of the process with titanium alloys. The capability of diffusion bonding process for similar and dissimilar titanium alloys was studied with five titanium alloys, Ti-64SG, Ti-64FG, Ti-6242SG, Ti-54M, and Beta-21S, by maintaining two governing parameters pressure and time constant while the temperature was varied during the formation of joints. The friction stir welding of similar and dissimilar titanium joints was also studied with five titanium alloys, Ti-64SG,Ti-64FG,Ti-6242SG,Ti-6242FG, and Ti-54MFG, by varying two parameters namely, spindle speed and the feed rate, that control the quality of the process. The bond integrity of both the processes was evaluated with metallographic examination and mechanical testing. The surface and subsurface characteristics were examined to evaluate the surface characteristics and bonding strength. The mechanical strength of diffusion-bonded joints was investigated by conducting flexure testing whereas of the friction stir welded joints were examined by performing tensile tests. The probabilistic theoretical model of estimation of bonding time of dissimilar alloys was developed by computing the surface topography at the joint interface. A combined approach of numerical and experimental methodology was used to investigate the mechanical response of different titanium joints. The numerical model was developed to simulate flexural behavior of dissimilar diffusion bonded titanium joints from the material curves of its parent alloys. Similarly tensile behavior of friction stir welded similar titanium alloys for different process conditions was developed to identify the locations of maximum stress and strain in the joints. The numerical results were compared to experimentally determined behavior characteristics of the joints to gage the validity of the modeling approach. It was found that there was good agreement in the numerical and experimental results of the tensile behavior in titanium FSW joints. The diffusion bonding temperatures lower than the ß transus temperature of titanium alloys were identified to obtain sound bonds in similar and dissimilar titanium alloys. The quality of bonding was improved as the bonding temperature was increased. In case of friction stir welding, the optimum values of spindle speed and feed rate for the joints formed by similar titanium alloys were 275 RPM/100 mm min-1, whereas it was 325RPM/125 mm min-1 for the joints formed by dissimilar titanium alloys.

Download or read book Manufacturing Methods Development of Spot Weld Adhesive Bonded Joining for Titanium written by Dallas Fields and published by . This book was released on 1971 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: Basic parameters were established for joining titanium alloy using the resistance spot-weld-adhesive bonding (weldbonding) PROCESS. Design of test parameters for evaluation of static strength of weldbond joints in titanium alloy required that first consideration be given to the probable use of the developed process. Since a high percentage of titanium used in joints of military aircraft would involve areas either exposed to high stress and/or elevated temperatures, strength at elevated temperatures was given prime consideration. Test results analysis showed that weldbond joints were superior in strength at room temperature as compared to all other joints tested. Weldbond joints and/or spot-weld joints were superior in strength in all categories from room temperature to 400 F as compared to other joints tested. Mechanical fasteners plus adhesive showed the third highest strength as compared to other joints. Structural adhesive bond joints were generally inferior in strength to all other joints from room temperature through 400 F. (Author-PL).

Download or read book Fusion Bonding of Polymer Composites written by C. Ageorges and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fusion bonding is one of the three methods available for joining composite and dissimilar materials. While the other two, mechanical fastening and adhesion bonding, have been the subject of wide coverage both in textbooks and monographs, fusion bonding is covered here substantially for the first time. Fusion bonding offers a number of advantages over traditional joining techniques and it is anticipated that its use will increase dramatically in the future because of the rise in the use of thermoplastic matrix composites and the growing necessity for recyclability of engineering assemblies. Fusion Bonding of Polymer Composites provides an in-depth understanding of the physical mechanisms involved in the fusion bonding process, covering such topics as: - heat transfer in fusion bonding; - modelling thermal degradation; - consolidation mechanisms; - crystallisation kinetics; - processing-microstructure-property relationship; - full-scale fusion bonding; - fusion bonding of thermosetting composite/thermoplastic composite and metal/thermoplastic joints. The book focuses on one practical case study using the resistance welding process. This example exposes the reader to the development of processing windows for a novel manufacturing process including the use of experimental test programmes and modelling strategies.
