Hybrid laser-arc welding (HLAW) is a combination of laser welding with arc welding that overcomes many of the shortfalls of both processes. This important book gives a comprehensive account of hybrid laser-arc welding technology and applications. The first part of the book reviews the characteristics of the process, including the properties of joints produced by hybrid laser-arc welding and ways of assessing weld quality. Part two discusses applications of the process to such metals as magnesium alloys, aluminium and steel

Laser and hybrid laser-arc welding are used at present in modern industry, having many advantages over traditional welding technology. Sectors such as the automotive industry, shipbuilding, aviation and space industry, chemical machinery, defense industry, and so on cannot be imagined without these technologies. Possibility of dramatic increase of weld joint properties, robustness, and high level of process automation makes the technology of laser and hybrid material processing a prospective part of the industry. At the same time, physical complexity of

The welding of Ni-base alloy Inconel 690 is commonly required during the construction and refurbishing of nuclear power plants with plate thicknesses varying between 1 mm to greater than 25 mm. However, during conventional multi-pass welding of Alloy 690 in this thickness range, micro-cracking in the form of ductility dip cracking (DDC) and solidification cracking can occur, causing significant delays in an already expensive industry. Hybrid laser-arc welding can significantly reduce the number of passes necessary to weld thick sections and, at the same

Hybrid laser-arc welding of nickel-base alloys can increase productivity and decrease costs during construction and repair of critical components in nuclear power plants. However, laser and hybrid welding of nickel-base alloys is not well understood. This project sought to understand the physical processes during hybrid welding necessary to fabricate quality joints in Alloy 690, a Ni- Cr-Fe alloy. This document presents a summary of the data and results collected over the course of the project. The supporting documents are a collection

Due to the wide application of magnesium alloys in metals manufacturing, it is very important to employ a reliable method of joining these reactive metals together and to other alloys. Welding and joining of magnesium alloys provides a detailed review of both established and new techniques for magnesium alloy welding and their characteristics, limitations and applications. Part one covers general issues in magnesium welding and joining, such as welding materials, metallurgy and the joining of magnesium alloys to other metals

As a fabrication technology, welding presents a number of technical challenges to the designer, manufacturer, and end-user of the welded structures. Both weld residual stress and distortion can significantly impair the performance and reliability of the welded structures. They must be properly dealt with during design, fabrication, and in-service use of the welded structures. There have been many significant and exciting developments on the subject in the past ten to fifteen years. Measurement techniques have been improved significantly. More importantly,

Hybrid welding, the combination of laser and arc welding, is being heavily investigated for potential applications in the fabrication of structural steel components. The hybrid process is an alternative to autogenous laser welding that requires good fit-up of the parts. With the hybrid process, the addition of filler metal alters the weld pass chemistry and fills any gaps that may occur. In some applications, the fit-up of parts is only part of the issue for laser welding. In some structural

Laser welding is a rapidly developing and versatile technology which has found increasing applications in industry and manufacturing. It allows the precision welding of small and hard-to-reach areas, and is particularly suitable for operation under computer or robotic control. The Handbook of laser welding technologies reviews the latest developments in the field and how they can be used across a variety of applications. Part one provides an introduction to the fundamentals of laser welding before moving on to explore developments

Welding induces local residual stress and strain in workpiece joining. These local phenomena lead to distortions in the workpieces and aspect defaults. The consequence is aspect defaults (distortions), which can be corrected by heating and hammering. When the assembled elements have large dimensions and need many joints executed by welding sequences, the aspect defaults can be created by non-optimized sequences. The focus of this study is the optimization of joint sequences (through the numerical simulation of sequences) to minimize distortions
