PURPOSE: A pin welding method and apparatus for manufacture of an armature type unit are provided to improve the durability of an armature type unit by vertically welding a connecting pin to a vibrator. CONSTITUTION: A pin welding method for manufacture of an armature type unit comprises the steps of: projecting a laser beam(620) to one end of a vibrator(340) to temporarily melt one end of the vibrator, inserting a pin(335) to the temporarily melted one end, and curing the one end to fix the pin. The vibrator is formed in a U shape and has a hole(510) on the other end. The laser beam arrives at the one end of the vibrator by passing through the hole. |
