Abstract:
1. A plasma welding method for a golf club head, comprising the steps of: preparing a club head body and a striking plate, and mounting the striking plate to the club head body between which a connection line is formed, the club head body including a toe portion, a blade portion, a neck portion, a sole portion and a hosel; forming an inclined surface on an outer circumference of the striking plate adjacent to the neck portion of the club head body such that a receiving groove is formed on the connection line; moving a plasma nozzle to aim to the connection line formed between the club head body and the striking plate before the plasma welding; tilting the plasma nozzle a predetermined inclined angle with respect to a direction of the combination of the club head body and the striking plate for the plasma welding such that a trajectory of the plasma nozzle avoids obstruction of the hosel of the club head body; and controlling the tilted plasma nozzle to weld the striking plate to the club head body.
