Advances in Vibration Welding Technology 840223

The primary objective of this paper will be to focus attention on recent major advances in vibration welding technology which directly apply to the automotive industry. Breakthroughs in large part welding capabilities, combined with product improvements, now extend the range of current joining possibilities, opening the way for new and innovative automotive product design.
Welding reinforcements up to 50” (127cm) long, to an all plastic bumper, has become a reality with the development of a large part vibration welder (LPVW). Currently in production, this new technology and equipment can also be applied to other large part applications, such as welding structural or support members onto large exterior components, i.e.: hood and trunk lids, quarter panels, valence panels and spoilers.
Improvements in standard sized welders such as advanced process controls and built-in flexibility will offer significant gains in weld quality, automation, adaptation and overall productivity.
A discussion of basic theory and principles of operation will be essential for background Information, along with equipment descriptions ranging from standard welders to special large part vibration welders. Details such as part size capabilities, operating parameters, and equipment selection relative to specific types of applications will be described thoroughly. Examples of successful assembly applications in areas such as fuel management, exterior lighting, ducts, and under-the-hood components will be used for capability familiarization.
