This book provides a basis for the design and analysis of welded components that are subjected to fluctuating forces, to avoid failure by fatigue. It is also a valuable resource for those on boards or commissions who are establishing fatigue design codes. For maximum benefit, readers should already have a working knowledge of the basics of fatigue and fracture mechanics. The purpose of designing a structure taking into consideration the limit state for fatigue damage is to ensure that the performance is satisfactory during the design life and that the survival probability is acceptable. The latter is achieved by the use of appropriate partial safety factors. This document has been prepared as the result of an initiative by Commissions XIII and XV of the International Institute of Welding (IIW).

Currently, most of the major commercial metal additive manufacturing (MAM) techniques rely on liquid phase processing. The liquid to solid phase transformations in these techniques results in microstructural issues and defects which in turn tantamount to inferior properties of fabricated build. Friction based additive manufacturing technologies are solid state processing techniques which work on the principles of friction based joining processes and layer by layer additive manufacturing. This book primarily addresses the basic understanding of seven friction based additive manufacturing techniques. These techniques include additive manufacturing methods based on rotary friction welding, linear friction welding, friction deposition, friction surfacing, friction stir additive manufacturing, friction assisted seam welding and additive friction stir. The principle of operations, benefits, limitations and recent developments of each technique has been described. It covers potentional and probable applications of each technique through review of various experimental studies.

This book describes the latest efforts to develop aluminum nanocomposites with enhanced damping and mechanical properties and good workability. The nanocomposites exhibited high strength, improved damping behavior and good ductility, making them suitable for use as wires. Since the production of metal matrix nanocomposites by conventional melting processes is considered extremely problematic (because of the poor wettability of the nanoparticles), different powder metallurgy routes were investigated, including high-energy ball milling and unconventional compaction methods. Special attention was paid to the structural characterization at the micro- and nanoscale, as uniform nanoparticle dispersion in metal matrix is of prime importance. The aluminum nanocomposites displayed an ultrafine microstructure reinforced with alumina nanoparticles produced in situ or added ex situ. The physical, mechanical and functional characteristics of the materials produced were evaluated using different mechanical tests and microstructure investigation techniques. The book presents and discusses the experimental results in detail, and offers suggestions for future research directions.

Welding is a skill any do-it-yourself enthusiast needs in his arsenal. It is only when you can join metal that you can properly repair and create. This book is the perfect introduction for beginners, and an excellent refresher for veteran welders, a work so comprehensive and so complete that most readers won't need any further instruction. "How To Weld" starts with a brief history of welding, an overview of different types of welding, and a thorough discussion of safety practices. Longtime welding instructor Todd Bridgum describes various tools and types of metals, as well as techniques and types of joints. Bridgum discusses gas, stick, wire-feed (MIG and TIG), even brazing, completing each section with a series of exercises that fully illustrate the skills he has covered. This book concludes with six projects, including construction of a welding table, gantry, and jack stands.

Robotic welding systems have been used in different types of manufacturing. They can provide several benefits in welding applications. The most prominent advantages of robotic welding are precision and productivity. Another benefit is that labor costs can be reduced. Robotic welding also reduces risk by moving the human welder/operator away from hazardous fumes and molten metal close to the welding arc. The robotic welding system usually involves measuring and identifying the component to be welded, we- ing it in position, controlling the welding parameters and documenting the produced welds. However, traditional robotic welding systems rely heavily upon human interv- tion. It does not seem that the traditional robotic welding techniques by themselves can cope well with uncertainties in the welding surroundings and conditions, e. g. variation of weld pool dynamics, fluxion, solid, weld torch, and etc. On the other hand, the advent of intelligent techniques provides us with a powerful tool for solving demanding re- world problems with uncertain and unpredictable environments. Therefore, it is intere- ing to gather current trends and to provide a high quality forum for engineers and researchers working in the filed of intelligent techniques for robotic welding systems. This volume brings together a broad range of invited and contributed papers that describe recent progress in this field.

Beim Voll-Vorwarts-Strangpressen werden Masse und Querschnittsform des Pressprodukts durch die formgebende Matrizenoffnung bestimmt. Diese unterliegt wahrend des Pressvorgangs starken mechanischen und thermischen Beanspruchungen, wodurch es zu einer vorgangsabhangigen Verformung des Matrizendurchbruchs kommt. Zusatzlich erfahrt das Pressprodukt wahrend des Erkaltens eine erhebliche Schwindung. Diese Faktoren mussen bereits bei der Matrizenkonstruktion berucksichtigt werden, was bis jetzt nach Erfahrungswerten geschieht. Die Methode der Finiten Elemente gestattet Aussagen uber belastungsbedingte Verformungen des Matrizendurchbruchs schon in der Konstruktionsphase. Durch die Idealisierung des Werkzeugsatzes einer Strangpresse und den Ansatz von Randbedingungen, die die jeweiligen Belastungen moglichst genau beschreiben, konnen Temperaturverhaltnisse und zu erwartende Werkzeugverformungen wahrend des Pressvorgangs profilspezifisch bestimmt und notwendige Matrizenkorrekturwerte konstruktiv berucksichtigt werden.
