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.
