Under this structure, there is no flexible space behind the hitting panel, and when hitting the ball, it hits The ball has poor flexibility, with a short time of 10, and low friction, especially when hitting the ball in the bunker, the disadvantage of 'cannot do more effective spinning stroke skills' will be more obvious. In addition-a kind of customary The iron head is filled with fiber-reinforced resin in a groove on the front of the head, and a metal plate is embedded in the groove, and a ball striking groove is provided on the metal plate to form the metal plate ^ Ball panel 15 under this structure The impact panel can push the fiber-reinforced resin backwards under high-speed impact. It has a deflection space and flexibility, which can increase the contact time with the ball and improve the disadvantages of the above head structure. However, the impact area is limited to On the front side of the embedded metal plate, the effective hitting area on the front side of the head is small. And because the metal plate is embedded in the groove, it can be seen on the front of the striking metal surface that it is clearly visible on the front of the head. There will be traces of fiber-reinforced resin around, and the overall appearance is inconsistent, which is the disadvantage of this conventional head.

A soft metal layer 20 is formed on the 11th peripheral surface. The hardness of the soft metal layer is below HRC9, and the thickness is in the recession 1. The soft metal layer is, for example, 2G thinner in the soft metal layer. In this embodiment, the layer system is a metal plate, which is embedded in the groove. 02mm A welding layer 30 is provided between the soft metal layer 20 and the bottom surface of the groove 11 for welding the soft metal layer 20 in the groove 11, and the thickness of the welding layer 30 is 0.02 mm To 0.06mm. In this embodiment, the thickness of the 5 welding layer 30 is 0.038 mm, which is formed by melting and welding a thin plate of an amorphous metal material formed by nickel-based hard solder, such as the American AWS Association No. BNI-2, and the American AMS Association. No. 4777F nickel-based hard solder. A thin batting surface layer 40 is provided on the front surface of the casing 10 and abuts against the annular shoulder 12. The hardness of the thin batting surface layer 40 is above HRC 35, and the thickness is 10 degrees and below 1.5 mm. The front surface of the thin hitting surface layer 40 is provided with several hitting grooves 41 to form a hitting surface 42. In this embodiment, the thin ball striking surface layer 40 is an abrasion-resistant metal plate and may be made of a hemp aging steel metal material. A welding layer 50, see the second and third figures, is disposed on the back of the thin ball 15 surface layer 40, and the thin ball surface layer 40 is welded to the annular shoulder 12 and the soft metal layer On 20, the thickness of the bonding layer 50 is between 0.02 mm and 0.06 mm. In this embodiment, the thickness of the soldering layer 50 is 0.038 mm, which is the same as the thickness of the soldering layer 30 between the soft metal layer 20 and the groove 11. An amorphous metal is also formed from nickel-based hard solder. Twenty thin sheets of material are formed by fusion welding, such as nickel-based hard solder of the American AWS Association No. BNI-2 and American AMS Association No. 4777F. An annular welding layer 60 can be welded on the outer peripheral surface of the thin ball striking surface layer 40 and the annular shoulder 12 as shown in the second and fourth figures to strengthen and fix the thin ball striking surface. The bond between the layer 40 and the shell 10. In the embodiment of this -6-new specification, the annular welding layer 60 is formed using ™ welding. Therefore, the original Pu club head is set on the back of the _ high hardness wear-resistant hitting surface-a soft metal layer, which can have a strong structural strength. When the hitting surface reaches the same speed, the material is a thin hitting surface. The layer can press the soft metal layer to produce a deflection effect, so that the ball striking surface has better flexibility and a better ball striking effect. In addition, the thin batting surface layer covers the entire front of the club hinge. In addition to having a larger effective shot area, it also visually sighs the overall shape of the club head. It should be noted that the soft metal layer of this creation may not be welded to the housing receiving portion using a welding layer as described in the above embodiment, or the soft metal layer may be directly fixed to the soft metal layer by mechanical manufacturing. The undertaking department can also achieve the purpose of cost creation. Therefore, those who have the thin batting surface layer and soft metal layered structure disclosed in this work to form the face of the head should be included in the scope of this work.
