Description

  The present invention relates to a golf club head, and more particularly to a golf club head having a connecting block structure.

  In the structure of the golf club head, the striking surface of the golf club head is the main point where the golf ball is in direct contact with the golf ball and a force is applied to the club head. High strength, stretchability and toughness were basically required for the material of the striking surface. In addition, the angle change that occurs on the striking surface of the club head is reduced, the toughness (easiness of elastic deformation) of the striking surface is improved, and the contact time is extended to improve the stability and the flight angle of the golf ball. It was important to design the striking surface.

  Please refer to FIG. FIG. 1 is a cross-sectional view showing a conventional golf club head. The conventional golf club head 900 enhances the hitting effect of the golf club head 900 by coupling the composite hitting surface 920 to the club head main body 910. The composite striking surface 920 is formed by coupling the first plate body 921 and the second plate body 922, and the first plate body 921 (for example, a titanium metal material) directly hits the golf ball. It is used for. The second plate 922 (for example, a stainless steel material) is made of a material having good weldability with the club head main body 910, and the composite striking surface 920 is coupled to the club head main body 910 by welding. Since the titanium metal material of the first plate 921 has characteristics such as light weight, high strength, and corrosion resistance, the golf club head 900 has obtained a high striking effect by the composite striking surface 920.

  However, in the coupling structure of the club head main body 910 and the composite striking surface 920, the weldability between the first plate body 921 (titanium metal) and the club head main body 910 is not good (that is, the first plate body). 921 and the club head main body 910 are not weld-bonded well), and the combined stability of the combined striking surface 920 and the club head main body 910 is reduced, and the structural strength and striking of the entire golf club head 900 are reduced. The effect could be adversely affected.
