Class Information
Number: 228/2.1
Name: Metal fusion bonding > Including means to provide heat by friction between relatively moving surfaces (i.e., friction welder)
Description: Device having means for causing motion, one with respect to the other, of either (a) two mutually engaging work portions or (b) a work portion and a work-engaging, tangible instrumentality, which rubbing contact generates heat sufficient to produce a flow of the metal work portion(s) for subsequent fusion bonding.
