Abstract:
A vehicle lamp vibration-type welding method comprising the steps of:(a) fitting a first workpiece having a joining portion into a lower receiving jig;(b) securing the first workpiece such that the joining portion does not resonate in a direction of vibration;(c) fitting a second workpiece having a joining portion into an upper receiving jig such that the joining portion of the second workpiece faces the joining portion of the first workpiece;(d) moving the lower receiving jig in a pressure direction until the joining portion of the first workpiece is pushed against the joining portion of the second workpiece under a predetermined pressure; and(e) vibrating the upper receiving jig in a direction perpendicular to the pressure direction to generate frictional heat and weld the joining portions of the first and the second workpieces together, such that one of the joining portions is wedged into the surface of the other joining portion.
