Abstract
A tip is welded appropriately using an energy beam. The tip is welded to a base portion by irradiating the interface between the base portion and the tip with the energy beam. The welding the tip to the base portion includes: applying the energy beam continuously, while moving the irradiation position of the energy beam, in a first period of time; and applying the energy beam a plurality of times according to a pulsed output pattern, while moving the irradiation position of the energy beam, in a second period of time subsequent to the first period of time.
