Book excerpt: Recent industrial criteria increasingly require the production of multi-material components. However, the manufacturing requirements of these components are not met by conventional welding techniques. Alternative solid-state technologies, such as impact-based processes, must be considered. The impact welding family is composed of several processes, such as explosion welding, magnetic pulse welding, vaporizing foil actuator welding, and laser impact welding. These processes present very different length scales, providing the impact welding family with a broad applicability range. A sample of the cutting-edge research that is being conducted on the multidisciplinary field of impact welding is presented in this book.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dissimilar material welding has grown in popularity in the lightweight design of biomedical, automotive, and aerospace products. However, welding of two or more different materials presents difficulties due to their notable mismatch in chemical, physical and mechanical properties. Some traditional joining methods are undesirable due to the formation of intermetallic compounds and thermally induced defects. These defects make the dissimilar welds unable to reliably serve in actual applications. Vaporizing Foil Actuator Welding (VFAW), an impact welding method, can minimize the abovementioned defects and join various dissimilar metals in solid state with reliable properties. This dissertation focuses on developing VFAW to join three metal pairs including Ti/stainless steel (SS), NiTi/SS, and NiTi/brass alloy. The process, microstructure, and properties of these dissimilar impact welds were explored through advanced techniques and compared with traditional welding methods. This work also introduces a new additive manufacturing method based on impact welding, called Ballistic Additive Manufacturing (BAM). The potential applications and overall long term vision of BAM were demonstrated. The results show that VFAW was effective in joining Ti and stainless steel. Ti/SS impact welds have reproducible macro- and micro-structure and show spatial heterogeneities at large and small length scales. Simulation shows that strength and failure modes are not affected adversely by the size of the central unbonded zone. Since mufflers in automobile could encounter thermal exposure ranging from 300 to 800 °C, a Nb interlayer was introduced to improve the thermal resistance. Both types of bonds give base metal failure in lap shear tests in as-welded condition. Guidelines for the production, properties and applications of these classes of welds are provided. High strength and fatigue resistant impact welds were produced between a NiTi shape memory alloy and dissimilar metals including SS and brass alloy for the first time. Good retention of the superelastic property and strength in the VFAW nitinol welds could be ascribed to the lack of heat affected zone formation, the solid-state bonding interfaces and the grain refinement near the interfaces. The unparalleled performance of these high-strength solid-state similar and dissimilar welds is a solution to the increasing demands of applications in various industrial fields including the medical, automotive, aerospace and electronic sectors. BAM is a new class of additive manufacturing processes achieved by the sequential solid-state impact welding of elements. In this work, BAM was found to be a promising technology that can be used to carry out crack repair and groove filling by either combined shearing and welding method or directly welding of thin flyer sheets to a pre-machined part. The overall long-term vision for BAM is to automate the manufacturing system so that quick and efficient repairment of damaged parts, impact fill welding of dissimilar metals, and fabrication of arbitrary shapes with graded compositions can be achieved at low process energies.

Download or read book Explosive Welding, Forming and Compaction written by T.Z. Blazynski and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: The last two decades have seen a steady and impressive development, and eventual industrial acceptance, of the high energy-rate manufact turing techniques based on the utilisation of energy available in an explo sive charge. Not only has it become economically viable to fabricate complex shapes and integrally bonded composites-which otherwise might not have been obtainable easily, if at all-but also a source of reasonably cheap energy and uniquely simple techniques, that often dispense with heavy equipment, have been made available to the engineer and applied scientist. The consolidation of theoretical knowledge and practical experience which we have witnessed in this area of activity in the last few years, combined with the growing industrial interest in the explosive forming, welding and compacting processes, makes it possible and also opportune to present, at this stage, an in-depth review of the state of the art. This book is a compendium of monographic contributions, each one of which represents a particular theoretical or industrial facet of the explosive operations. The contributions come from a number of practising engineers and scientists who seek to establish the present state of knowledge in the areas of the formation and propagation of shock and stress waves in metals, their metallurgical effects, and the methods of experimental assessment of these phenomena.
Book Synopsis Thermo-Mechanical Modeling of Additive Manufacturing by : Michael Gouge
Download or read book Thermo-Mechanical Modeling of Additive Manufacturing written by Michael Gouge and published by Butterworth-Heinemann. This book was released on 2017-08-03 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thermo-mechanical Modeling of Additive Manufacturing provides the background, methodology and description of modeling techniques to enable the reader to perform their own accurate and reliable simulations of any additive process. Part I provides an in depth introduction to the fundamentals of additive manufacturing modeling, a description of adaptive mesh strategies, a thorough description of thermal losses and a discussion of residual stress and distortion. Part II applies the engineering fundamentals to direct energy deposition processes including laser cladding, LENS builds, large electron beam parts and an exploration of residual stress and deformation mitigation strategies. Part III concerns the thermo-mechanical modeling of powder bed processes with a description of the heat input model, classical thermo-mechanical modeling, and part scale modeling. The book serves as an essential reference for engineers and technicians in both industry and academia, performing both research and full-scale production. Additive manufacturing processes are revolutionizing production throughout industry. These technologies enable the cost-effective manufacture of small lot parts, rapid repair of damaged components and construction of previously impossible-to-produce geometries. However, the large thermal gradients inherent in these processes incur large residual stresses and mechanical distortion, which can push the finished component out of engineering tolerance. Costly trial-and-error methods are commonly used for failure mitigation. Finite element modeling provides a compelling alternative, allowing for the prediction of residual stresses and distortion, and thus a tool to investigate methods of failure mitigation prior to building. Provides understanding of important components in the finite element modeling of additive manufacturing processes necessary to obtain accurate results Offers a deeper understanding of how the thermal gradients inherent in additive manufacturing induce distortion and residual stresses, and how to mitigate these undesirable phenomena Includes a set of strategies for the modeler to improve computational efficiency when simulating various additive manufacturing processes Serves as an essential reference for engineers and technicians in both industry and academia

Book Synopsis Process Development and Capabilities of Chemically Augmented Laser Impact Welding by : Troy Brayden Lewis
Download or read book Process Development and Capabilities of Chemically Augmented Laser Impact Welding written by Troy Brayden Lewis and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The process of laser impact welding utilizes impact welding and laser-driven flyers to form solid-state, metallurgical welds between similar or dissimilar metallic flyers and targets. With chemically augmented laser impact welding, stronger and thicker metal flyers and targets can be welded together. Using a high-powered laser, a laser pulse is shot through a transparent tamping layer onto a translucent layer of chemical liquid and the bare surface of a metallic flyer. The energy from the laser pulse detonates the chemical augment and the pressure created from the explosion is confined by the tamping layer. This pressure is directed towards the flyer that is then driven to velocities in the hundreds of meters per second within 20 microseconds. Under the correct conditions, high speed and acceptable impact angle between the flyer and target, jetting will occur. The jet cleans the surface of the flyer and target of oxides, and the two surfaces will form a solid-state, metallurgical bond. Using a chemical augment, thicker, stronger flyers and targets can be welded compared to unaugmented laser impact welding. With the chemical augment, a 3J, 8.1ns laser pulse can weld a 0.5mm Al2024-T3 flyer to a 0.5mm Al2024-T3 target. To explore the capabilities of chemically augmented laser impact welding, two chemical augments were used as candidates for the process. Various tamping materials and thicknesses were also investigated along with variance in the laser spot diameter. The velocities of flyers were measured using Photon Doppler Velocimetry and a thicker tamping layer produced higher velocities and larger deformations than thinner tamping layers did with the same parameters. The strength of the welds between 0.5mm Al2024-T3 flyers and targets were also measured using a tensile test. Over two-thirds of the welded samples failed by nugget pullout during these tensile tests, validating the strength of the welds formed. Micrographs of a welded sample were also collected to observe the welded and unwelded regions. Finally, future work to advance chemically augmented laser impact welding is discussed.
