DEFINITION

Classification: 228/2.1

INCLUDING MEANS TO PROVIDE HEAT BY FRICTION BETWEEN RELATIVELY MOVING SURFACES (I.E., FRICTION WELDER):

(under the class definition) 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.
