DEVELOPMENT OF ULTRASONIC WELDING EQUIPMENT FOR REFRACTORY METALS

Abstract

Design, development, and construction of the 25-kilowatt spot-type welding machine has continued. Experience gained during the evaluation of ceramic transducer assemblies was used to design a 4.2-kilowatt unit. This assembly incorporates all the modifications previously found desirable to improve the electrical characteristics and facilitate heat removal from the ceramic elements. An extensive study of the test model of the overhung-coupler geometry revealed the factors contributing to its unsatisfactory behavior, and necessary modifications are being made. Assembly of the 25kilowatt power source was completed and acceptance tests were conducted by Aeroprojects personnel. The equipment performance was satisfactory, and the complete assembly was delivered to Aeroprojects. Installation of welder control components on the 25- kilowatt welder frame was completed.
