For the economical construction of offshore structures and pipelines, a clear need exists for welding processes which are capable of depositing weld metal of high integrity and toughness, and which offer significantly improved productivity, relative to the conventional, shielded metal arc welding process. This report examines the potential of pulsed gas metal arc welding (GMAW) for these applications. The report describes a study of the influence of shielding gas composition on pulsed GMAW characteristics and weld metal mechanical properties to determine the optimum gas mixures for the pulsed GMAW of structural and pipeline steels for offshore oil and gas installations. Preferred oxygen potential was determined through an investigation of the effect of variations in CO2 content of Ar-CO2 gas mixtures on weld metal properties. Maintaining the oxygen potential constant for each welding application, the effect of additions of He and H2 and variations in CO2 and O2 content on arc stability and metal transfer and on penetration and fusion characteristics were investigated.

For the economic construction of offshore structures and pipelines and ofArctic vessels, a need exists for welding processes which are capable ofdepositing weld metal of high integrity and toughness, with significantlyimproved productivity relative to the conventional shielded metal arc weldprocess. This report examines the potential of mechanized, pulsed gas metalarc welding and describes studies of metal transfer, burn-off and fusioncharacteristics using a range of wire and shielding gas combinations, leadingto the establishment of optimum pulse structure and synergic logic.

T. H. NORTH Dept. of Metallurgy and Materials Science, University of Toronto. This volume documents the proceedings of the International Congress on Joining Research held under the auspices of the Canadian Council of the International Institute of Welding in Montreal, July 20/21 1990. This congress was sponsored by the Welding Institute of Canada, Oakville, Ontario. The study of joining is important, both from the fundamental and applied science points of view. Joining encompasses a wide range of areas, from welding processes, through welding metallurgy and materials science, to non-destructive testing, automation and field construction. Welding has sometimes been referred to as some curious combination of art and science. Certainly, from a university research perspective, the welding area is remarkably difficult to tackle because it is extremely difficult to sift out the critical variables. As a result, it is sometimes difficult to separate the real from the imaginary in any detailed evaluation of the joining literature. I sincerely hope that the authoritative contributions in this volume will sweep away any confusion that exists in the mind of the reader.

This monograph is a first-of-its-kind compilation on high deposition pulse current GMAW process. The nine chapters of this monograph may serve as a comprehensive knowledge tool to use advanced welding engineering in prospective applications. The contents of this book will prove useful to the shop floor welding engineer in handling this otherwise critical welding process with confidence. It will also serve to inspire researchers to think critically on more versatile applications of the unique nature of pulse current in GMAW process to develop cutting edge welding technology.

Welding for Challenging Environments documents the proceedings of the International Conference on Welding for Challenging Environments held in Ontario, Canada on October 15-17, 1985. This compilation provides a unique reference to the state of technological development, research, and application of welded fabrications in challenging environments. This book discusses the developments in pulsed gas metal arc welding; pulsed FM-GMA welding; and narrow gap welding of pressure vessels. The fracture toughness considerations for offshore structures; microcomputer method for predicting preheat temperatures; and submerged arc welding of high yield strength steel are also elaborated. This text likewise covers the influence of nitrogen content on deposited weld metal notch toughness gas-metal-slag interactions of binary fluxes containing CaF2 and evaluation of susceptibility of welds made with a stable austenitic welding wire to hot cracking. This publication is a good source for welders and metallurgists, as well as students interested in welded fabrications in challenging environments.
