DEVELOPMENT OF ULTRASONIC WELDING EQUIPMENT FOR REFRACTORY METALS

Abstract

Joining refractory and superalloy metals in thicknesses up to 0.10 in. by ultrasonic welding is feasible. A first approximation of the ACOUSTICAL ENERGY REQUIRED INDICATES THAT THE REQUISITE WELDING EQUIPMENT IS ALSO FEASIBLE. The report is a compilation and discussion of information pertinent to the development of ultrasonic welding equipment for joining AM-355 steel, Inconel X, Rene 41, W, Mo-0.5% Ti, and Nb alloy (duPont D-31). The feasibility of welding the materials and gages of interest is supported by data, appropriately referenced, from previous work with thinner material. Information on transducer, coupler, and tip materials is presented with information on evaluating efficiency and practicability. Design information on spot-type and roller-seam welding machine tips is presented. Data on various properties of the weldment materials are tabulated.
