Development of Ultrasonic Welding Equipment for Refractory Metals
Abstract
The demonstrated feasibility of ultrasonically welding thin sheets of Nb(D-31), Inconel X-750, Mo-0.5Ti, PH15-7Mo, Rene 41 and W was extended to heavier gages of these materials. Measurement of the acoustical energy required confirm values previously estimated by an equation devised during fundamental research work. Salient problems associated with high power ultrasonic transducer-coupling systems for welding machines were considered and solutions were formulated. Thus, the ultrasonic welding of both mono- and bi-metal combinations in gages up to 0.10 in. is considered feasible. Information pertinent to the development of ultrasonic welding equipment for joining such materials is summarized. A first approximation of the energy required was supplemented by new data obtained by ultrasonically welding these materials in gages up to 0.040 in. with a 6 to 8 Kw laboratory device; thus, confirming the feasibility of joining such materials and of developing the necessary equipment to produce such junctions in thickness up to 0.10 in. Pertinent information on transducer, coupler, and terminal element materials is presented.
