DEFINITION

Classification: 219/86.1

By spot bonding:

(under subclass 78.01) Subject matter wherein welding is made between or upon overlapping members, coalescence may start and occur on the faying surfaces or may have proceeded from the surface of one member, and the weld cross section is approximately circular.

(1) Note. This subclass relates, for example, to spot welding of two overlapped plates where the spot weld is a substitute for a bolt or rivet connection.
