Book Description
The present state of the art and future developments necessary for successful commercial application of high-strength materials in welded structures are reported. The 10Ni-8Co-2Cr-1Mo steel and the Ti-6Al-2Cb-1Ta-0.8Mo titanium alloy were selected as candidate materials on the basis of their outstanding fracture-resistance characteristics and their roughly equivalent strength-to-weight ratios. The availability; chemical composition, physical, and mechanical properties; and heat treatment and metallurgical characteristics of both candidate materials are summarized. A general review of the problems and potential of the various welding processes is included and those processes that show greatest promise and should be further developed are identified. The available information on the mechanical properties of state-of-the-art welds (made for the most part under laboratory conditions) also is discussed.
