Available in PDF, EPUB and Kindle. Book excerpt: HE ORIGINS of welding are buried in the depths of antiquity, T commencing with the forging of native gold and copper, progressing in the bronze age with the braze welding of castings, but not developing greatly until relatively recently. It has been this century, and the latter half in particular, that welding has developed to the stage where there are more than 100 variants. Furthermore, joining by welding has become such an efficient technique that much of our modem way oflife would not be possible without it. The giant oil rigs, built to withstand the rigours of the North Sea, the minute wire connectors in the computer and transistor, and the automobile and truck, could not exist were it not for welding processes. Originally a uniquely manual process, the needs of industry have this century required welding techniques which could be mechanised. Some processes, such as friction welding, were readily mechanised but the most flexible and adaptable fusion processes awaited develop ments which allowed a continuous wire to be rapidly fed into the fusion zone. These processes, such as MAG and submerged arc, rapidly gave rise to machines for welding, with many appearing before the Second World War.

Available in PDF, EPUB and Kindle. Book excerpt: Automation and Robotisation in Welding and Allied Processes contains the proceedings of the International Conference on Automation and Robotization in Welding and Allied Processes held in Strasbourg, France, on September 2-3, 1985, under the auspices of the International Institute of Welding. The papers explore developments in the mechanization, automation, and utilization of robots in welding and related processes and cover topics such as half and fully mechanized welding of offshore constructions; adaptive systems of process control for spot welding robotic cells; and application of computer integrated manufacture to welder fabrication. This book is divided into two sections and begins with an overview of technical, economic, and human factors relating to mechanization and automation in arc and resistance welding. The next chapter describes a closed-loop controlled arc welding power source using a microcomputer as controller. The discussion then turns to problems associated with half and fully mechanized welding of offshore constructions; flexible manufacturing systems comprising welding with high productivity in small lot production; and the main factors causing process disturbance in spot welding. The final chapter is devoted to advanced adaptive control of automated arc welded fabrication which involves sensor application for seam tracking and joint recognition, preprogramming and online supervision of process parameters, and the design of a closed adaptive control loop. This monograph will be of interest to mechanical, electronics, industrial, and robotics engineers.

Download or read book A Practical Guide to Welding Solutions written by Robert W. Messler, Jr. and published by John Wiley & Sons. This book was released on 2019-01-14 with total page 442 pages. Available in PDF, EPUB and Kindle. Book excerpt: As critically important as welding is to a wide spectrum of manufacturing, construction, and repair, it is not without its problems. Those dependent on welding know only too well how easy it is to find information on the host of available processes and on the essential metallurgy that can enable success, but how frustratingly difficult it can be to find guidance on solving problems that sooner or later arise with welding, welds, or weldments. Here for the first time is the book those that practice and/or depend upon welding have needed and awaited. A Practical Guide to Welding Solutions addresses the numerous technical and material-specific issues that can interfere with success. Renowned industrial and academic welding expert and prolific author and speaker Robert W. Messler, Jr. guides readers to the solutions they seek with a well-organized search based on how a problem manifests itself (i.e., as distortion, defect, or appearance), where it appears (i.e., in the fusion zone heat-affected zone, or base metal), or it certain materials or situations.

Download or read book IIW Recommendations On Methods for Improving the Fatigue Strength of Welded Joints written by P J Haagensen and published by Woodhead Publishing. This book was released on 2013-01-25 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: The weld toe is a primary source of fatigue cracking because of the severity of the stress concentration it produces. Weld toe improvement can increase the fatigue strength of new structures significantly. It can also be used to repair or upgrade existing structures. However, in practice there have been wide variations in the actual improvements in fatigue strength achieved. Based on an extensive testing programme organised by the IIW, this report reviews the main methods for weld toe improvement to increase fatigue strength: burr grinding, TIG dressing and hammer and needle peening. The report provides specifications for the practical use of each method, including equipment, weld preparation and operation. It also offers guidance on inspection, quality control and training as well as assessments of fatigue strength and thickness effects possible with each technique. IIW recommendations on methods for improving the fatigue strength of welded joints will allow a more consistent use of these methods and more predictable increases in fatigue strength.

Download or read book Fracture Mechanics and Crack Growth written by Naman Recho and published by John Wiley & Sons. This book was released on 2012-12-27 with total page 347 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents recent advances related to the following two topics: how mechanical fields close to material or geometrical singularities such as cracks can be determined; how failure criteria can be established according to the singularity degrees related to these discontinuities. Concerning the determination of mechanical fields close to a crack tip, the first part of the book presents most of the traditional methods in order to classify them into two major categories. The first is based on the stress field, such as the Airy function, and the second resolves the problem from functions related to displacement fields. Following this, a new method based on the Hamiltonian system is presented in great detail. Local and energetic approaches to fracture are used in order to determine the fracture parameters such as stress intensity factor and energy release rate. The second part of the book describes methodologies to establish the critical fracture loads and the crack growth criteria. Singular fields for homogeneous and non-homogeneous problems near crack tips, v-notches, interfaces, etc. associated with the crack initiation and propagation laws in elastic and elastic-plastic media, allow us to determine the basis of failure criteria. Each phenomenon studied is dealt with according to its conceptual and theoretical modeling, to its use in the criteria of fracture resistance; and finally to its implementation in terms of feasibility and numerical application. Contents 1. Introduction. Part 1: Stress Field Analysis Close to the Crack Tip 2. Review of Continuum Mechanics and the Behavior Laws. 3. Overview of Fracture Mechanics. 4. Fracture Mechanics. 5. Introduction to the Finite Element Analysis of Cracked Structures. Part 2: Crack Growth Criteria 6. Crack Propagation. 7.
