WELDING PROCEDURES FOR TITANIUM AND TITANIUM ALLOYS
Abstract:
The report covers the state of the art of welding procedures for titanium and its alloys. Methods employed in the past and present are described. Many of the conventional welding and brazing processes are used for joining titanium and its alloys. Information on the use of these processes, when available, was condensed or extracted and included in this report. Necessary additional processing such as preweld cleaning, joint preparation, postweld cleaning, and postweld operations are also included since they form an integral part of the welding processes without which successful welding cannot be accomplished. Joining processes that have been used only experimentally also are described briefly. The need for proper preweld cleaning operations and proper shielding to prevent contamination of titanium welds is emphasized throughout.
