This bonding method permits the joining of thin-to-thin or thin-to-thick materials, including dissimilar metal joints. Bending stress is eliminated by positioning the line of force directly over the welding surface. Dependability is assured by utilizing shear mode vibration that is parallel to the welding surface. This system maximizes metal welding effectiveness by combining low vibratory amplitude with high vibratory force. Sonobond's Unique 'Wedge-Reed' Bonding System Sonobond's metal spot welders have an important advantage over other types of ultrasonic metal welding equipment because they use the unique, patented 'Wedge-Reed' bonding system. It contains an in-depth explanation of the process and principles involved in ultrasonic metal welding, as well as helpful information about equipment and applications. In this way, non-ferrous similar and dissimilar metals can be welded with repeated accuracy. This is accomplished by introducing high-frequency vibration while the weldment is under moderately high clamping force. Sonobond ultrasonic metal welders create precise, solid-state metallurgical bonds without heat, current, or consumables. Since then, the company has been the worldwide leader in the development of ultrasonic metal welding equipment. 5 The first patent ever issued for ultrasonic metal welding was awarded to Sonobond Ultrasonics (then known as Aeroprojects) in 1960.Mechanical Engineer ASNT Level III ET/MT/PT/RT/UT/VT.
