Talk:Ultrasonic welding

From Wikipedia, the free encyclopedia

[edit] Uhhm

"Although there is heating, it is not enough to melt the base materials. Vibrations are introduced along the joint being welded.....Ultrasonic welding appeared in the mid 60's and is rapidly developing. In its infancy, only hard plastics could be welded because their properties were the only fitting—they were acoustically conductive and had a low melting point."
