Be Advanced Welding Processes

Posted by syico | 12:07:00 AM | | 0 comments »

Welding has traditionally been regarded as a craft rather than a technological manufacturing process. This reputation has not been helped by the dependence of conventional joining techniques on highly skilled manual operators and the relatively high cost and poor reproduceability associated with many welding processes.

Developments in welding technology have in the past been based largely on metallurgical research, which has enabled a wide range of materials to be joined, adequate joint properties to be maintained and the integrity of welded joints to be con- trolled. Whilst further work is still required in the materials research area, in particular to enable advanced materials to be joined effectively, much of the recent effort has been devoted to improved understanding of the basic processes, consumable and equipment development and control and automation.

This book outlines the common production welding processes, discusses developments in
consumables and processes and covers in some detail the developments in electronic power regulation, computer control, automation and process monitoring. It attempts to draw together the latest work in each area and indicates how the advances in welding technology may be used to produce cost-effective joints of appropriate quality.
