Abstract
A plasma welding method for a golf club head includes the steps of: preparing a club head body and a striking plate, and mounting the striking plate to the club head body; moving a plasma nozzle to aim to a 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 vertical direction of the combination of the club head body and the striking plate for the plasma welding; and controlling the tilted plasma nozzle to weld the striking plate to the club head body so as to constitute the golf club head.
Claims18
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.

A manufacturing 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 a first inclined surface on an inner circumference of a front opening of the club head body and forming a second inclined surface on an outer circumference of the striking plate, the first and second inclined surfaces being arranged adjacent to the neck portion of the club head body such that a receiving groove is formed between the first and second inclined surfaces;
- 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.

A plasma welding method for a golf club head, comprising the steps of:
- preparing a first club head component and a second club head component, and mounting the first club head component to the second club head component between which a connection line is formed, the second club head component including a barrier portion;
- forming an inclined surface on the first club head component adjacent to the barrier portion of the second club head component such that a receiving groove is formed on the connection line;
- moving a plasma nozzle to aim to the connection line formed between the first and second club head components before the plasma welding;
- tilting the plasma nozzle a predetermined inclined angle with respect to a direction of the combination of the first and second club head components for the plasma welding such that a trajectory of the plasma nozzle avoids obstruction of the barrier portion of the first club head component;
- and
- controlling the tilted plasma nozzle to weld the first club head component to the second club head component.
