DEVELOPMENT OF NEW IMPROVED TECHNIQUES FOR UNDERWATER WELDING

This comprehensive report describes the results of a 2-1/2- year research effort to develop underwater welding techniques capable of producing durable, hard welds economically. During the initial phase of the project, several new, improved processes were conceived. Two were then chosen for full development. One, stud welding, an arc welding process, was selected because of the ease of application by one, minimally trained diver. The second, flux-shielded welding, offered the advantage of being able to operate free of a gas supply, making it good for deep sea diving. Another feature, a direct flux covering, minimized water contact. Both processes were tested in the M.I.T. welding laboratory and then subjected to actual diving conditions in the Baltic Sea during a cooperative experimental venture between U.S. and German scientists. The report which provides an overview of world-wide underwater welding research, also includes a bibliography on all literature published on the subject since 1930.
