• 1 • 2 • 3 • 4 • 5 The first patent ever issued for ultrasonic metal welding was awarded to Sonobond Ultrasonics (then known as Aeroprojects) in 1960. Since then, the company has been the worldwide leader in the development of ultrasonic metal welding equipment. Sonobond ultrasonic metal welders create precise, solid-state metallurgical bonds without heat, current, or consumables. This is accomplished by introducing high-frequency vibration while the weldment is under moderately high clamping force.

In this way, non-ferrous similar and dissimilar metals can be welded with repeated accuracy.. 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. 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. This system maximizes metal welding effectiveness by combining low vibratory amplitude with high vibratory force. Dependability is assured by utilizing shear mode vibration that is parallel to the welding surface. Bending stress is eliminated by positioning the line of force directly over the welding surface. This bonding method permits the joining of thin-to-thin or thin-to-thick materials, including dissimilar metal joints.

Reducing Pipeline Construction Costs With Girth Weld. Luger Serial Number Database. Defect acceptance criteria for pipeline girth welds. N Advancements in automated ultrasonic testing. Full-text (PDF) Automated ultrasonics (AUT) is more reliable, faster, has better detection of critical Lack of Fusion defects in pipeline construction welds, and.

It produces joints with good thermal and electrical conductivity, while welding through most oxides and tinned metals. No special cleaning process is required. This technical data sheet contains in-depth explanations of the two systems used for ultrasonic metal welding—Sonobond's patented Wedge-Reed System and our competitors' lateral drive system. A comparison of both systems' design and operation; their capabilities, amplitude and force differences; and the importance of matching system and load impedance are included.
