This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of the research, through both an experimental and a modelling approach, was to determine the parameters controlling the nitrogen level in a weld. A second objective was to study the relationship between the weld microstructure and the corrosion properties. More particularly, the potential interest of microelectrode techniques has been investigated. TIG welding has been investigated through both an experimental and a modelling approach. TIG and A TIG tests have confirmed tnat it is necessary to add nitrogen in the shielding gas in order to prevent nitrogen loss during welding. For duplex stainless steel, 2.5 % nitrogen in the shielding gas is sufficient, whereas for high nitrogen content austenitic stainless steels higher levels are necessary. It has also been shown that, for a given grade, the nitrogen content increases when the penetration increases. Penetration depends on the material composition, with a beneficial effect of surface active elements (0, S, etc.). The model developed was based on the nitrogen exchange between the plasma, the weld pool and the shielding gas. It was first developed to describe nitrogen evolution during a stationary arc situation. The results were in good agreement with experiments. The model was then adapted to the case of welding with an active flux. An attempt was made to describe the traveling arc situation. However, some improvements are still necessary. Pitting corrosion tests have confirmed the influence of nitrogen content on the corrosion sensitivity of TIG welds. Microelectrode techniques have been used to characterise the local corrosion behaviour of welds. It has been shown that the scanning vibrating electrode technique was of limited utility to study corrosion resistance of highly alloyed stainless steels. More promising results have been obtained with microcapillary technique which make local electrochemical measurements possible. Finally, MIG tests have been performed in order to study the influence of the shielding gas composition on nitrogen content in the weld and also on the formation of porosities. For superduplex stainless steel, it has been demonstrated that nitrogen must be added in the gas to prevent nitrogen loss. It has also been shown that the number of porosities in the weld depends on the C02 content in the gas and not on the nitrogen content.

Download or read book Fusion Welding of Advanced Borated Stainless Steels Final Report written by and published by . This book was released on 1994 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work addressed two major areas concerning joining of advanced borated stainless steels. These areas included the development of a understanding of the physical metallurgy of borated stainless steels and the development of welding processes and post-weld heat treatments for these alloys. Differential thermal analysis experiments were conducted on ten heats of borated stainless steel to determine the transformation temperatures and melting behavior of the alloys. On-heating solidus temperatures were measured for all of the alloys and were used to define the temperatures associated with the fusion line during welding. Isothermal heat treatments designed to evaluate the effects of elevated temperature exposures on the toughness of the borated grades were conducted. These tests were used to determine if significant changes in the microstructure or mechanical properties of weld heat-affected zones (HAZ) occur. Specifically, the tests addressed the solid-state region of the HAZ. The test matrix included a variety of alloy compositions and thermal exposures at temperatures near the on-heating solidus (as determined by the DTA experiments). Welding experiments designed to assess the mechanical properties and microstructure of gas-tungsten arc and electron beam welds were conducted.

Download or read book Welded Design written by John G. Hicks and published by Woodhead Publishing. This book was released on 2001 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: Welded design is often considered as an area in which there's lots of practice but little theory. Welded design tends to be overlooked in engineering courses and many engineering students and engineers find materials and metallurgy complicated subjects. Engineering decisions at the design stage need to take account of the properties of a material - if these decisions are wrong failures and even catastrophes can result. Many engineering catastrophes have their origins in the use of irrelevant or invalid methods of analysis, incomplete information or the lack of understanding of material behaviour. The activity of engineering design calls on the knowledge of a variety of engineering disciplines. With his wide engineering background and accumulated knowledge, John Hicks is able to show how a skilled engineer may use materials in an effective and economic way and make decisions on the need for the positioning of joints, be they permanent or temporary, between similar and dissimilar materials. This book provides practising engineers, teachers and students with the necessary background to welding processes and methods of design employed in welded fabrication. It explains how design practices are derived from experimental and theoretical studies to produce practical and economic fabrication.

This book was released on 2024-09-04 with total page 548 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book highlights the important use of digital technologies and the latest developments in mechanical and industrial engineering to enhance environmental and resource sustainability. Sustainable Development Goals (SDGs) have as their overarching objective the reduction or eradication of a wide range of global problems, including, but not limited to poverty, climate change, environmental degradation, and inequality. Digital technologies (DTs) have the potential to be exploited to meet the goals associated with the circular economy (CE) and sustainable development. Additive manufacturing (AM), cyber-physical systems (CPS), and blockchain technology are examples of DT-enabled technologies that are helpful for businesses that seek to shift to a circular economic model. With the remanufacturing of products, applications that make use of virtual reality and augmented reality, in addition to the Internet of Things, simplify the construction of strategic decision models that reduce time and expense while simultaneously increasing productivity. In addition, the utilization of big data analytics helps businesses discover previously undisclosed trends and unlock numerous opportunities for environmental and resource sustainability. Employing analytics makes it feasible to collect helpful information regarding the socio-environmental impact of a product, as well as consumption factors over the entirety of a product’s life cycle. This book contains 44 comprehensive chapters and is divided into five parts. Part 1 delves deeply into sustainable operational practices and supply chain management. The impact that digital technology-enabled operational techniques have on product life cycles is investigated, as well as the design of efficient remanufacturing processes, environmentally friendly logistics and warehousing practices, sustainable designs for distributed energy supply systems, and efficient recycling procedures. Part 2 provides a perspective on advanced materials and developments for sustainable manufacturing. The chapters in this section address sustainable material development and its application in the circular economy concept. Included here is an in-depth exploration of cutting-edge technology for synthesis, processing, fabrication, process optimization, testing, and performance evaluation of advanced materials. Part 3 covers sustainable manufacturing practices and looks at the problems faced by the industry when using digital technologies in their operations, as well as the possible benefits. Part 4 examines sustainable innovation in mechanical design. It addresses all aspects of mechanical design that contribute to sustainable innovation for nation-building. Part 5 delves into heat transfer and fluid flow concepts for sustainable product development and applications. The chapters explain how to construct sustainable energy systems by reducing the total amount of energy that is utilized, enhancing the efficiency of the process of energy conversion, and making use of sources of energy that are renewable. Audience This book has a wide audience in academic institutions and engineers in a variety of manufacturing industries. It will also appeal to economists and policymakers working on the circular economy, clean tech investors, industrial decision-makers, and environmental professionals.
