M255045 捌、新型說明： 【新型所屬之技術領域】 本創作係關於中空高爾夫球桿頭，特別關於設置有配重 材料的高爾夫球桿頭。 【先前技術】 為了調整鋼或鈦合金等的金屬製的中空高爾夫球桿頭 的重心高度或重心深度、或高爾夫球桿頭的平衡等，有時 在底部配置用鎢等高比重材料構成的配重材料。 當桿頭本體由鈦合金等的低比重的金屬構成，配重材料 用鎢或是鎢合金構成的時候，把桿頭本體和配重材料一起 焊接極其困難。在曰本專利特開平1 〇 - 9 4 6 2 3號公報中，描 述了在用鎢構成的質量體的外周圍，嵌接或捲接和桿頭本 體的底材同一材質的筒狀、帶狀或是線狀的材料，然後將 其焊接在底部。 (專利文獻） 曰本專利特開平1 0 - 9 4 6 2 3號公報 【新型内容】 (創作所欲解決之問題） 上述日本特開平 1 0 - 9 4 6 2 3號公報中的高爾夫球桿頭， 在質量體的外周上，由於嵌接或捲接和桿頭本體的底材同 一材質的材料後要進行焊接，所以安裝質量體很費事。另 外，在質量體同嵌接或捲接在質量體上的周圍材的介面間 會浸入水分，也恐怕要降低高爾夫球桿頭的财久性。 本創作目的在於為解決上述現有問題點，提供一種高爾 4 M255045 夫球桿頭，使其安裝的配重材料既堅固，又具有優越的耐 久性，同時也容易製作。 (解決問題之手段） 本創作的高爾夫球桿頭是具有中空桿頭本體的高爾夫 球桿頭，在該桿頭本體的向下表面部分，至少有一部分是 金屬製，高爾夫球桿頭的該金屬部分固定有配重材料的高 爾夫球桿頭中，其特徵在於：相對於該高爾夫球桿頭本體， 配重材料實際上僅是通過焊接被安裝，在高爾夫球桿頭的 主體上設置有開口或從外面向内凹陷的凹部，在該開口或 是凹部繫合上述的配重材料，該配重材料的外緣部相對該 開口或是凹部的内緣部進行焊接。 再者，所謂的向下表面部分是指球桿底部、側部及其他 實質是與冠部相對的向下表面部。 本創作係關於高爾夫球桿頭，配重材料相對於桿頭本體 實際上僅是通過焊接被安裝著，配重材料的安裝既堅固， 又具有優越的耐久性，同時也容易製作。 本創作中最好是進行焊接，把形成的焊道埋入在配重材 料的外緣同開口或凹部的内緣部之間的縫隙處。最佳的焊 接是能夠容易形成焊道的電弧焊接或電漿焊。 本創作中的桿頭本體最好全部是金屬製，但也可以一部 分是碳纖維強化合成樹脂等。 當把高爾夫球桿頭做成球道木桿或多功能桿的高爾夫 球桿頭時，該金屬的比重最好是6. 5〜8. 5。以比重為6. 5 7 的不銹鋼為例說明滿足該比重的特別合適的金屬材 5 M255045 料。 配重材料的比重最好是1 0〜1 3。利用使配重材料為鑄造 品，能夠容易製造出尺寸精度準確的配重材料。 本創作中的配重材料最適合是鶴合金。特別當桿頭本體 是不銹鋼製的時候，最好是容易同不銹鋼進行焊接的鐵· 鎢合金。 以下，就合適的組成範圍進行詳細的說明。 【實施方式】 以下根據附圖對具體實施例進行說明。圖1是從底面看 到的根據實施形態的高爾夫球桿頭的立體圖，圖2是沿著 圖 1中的Π - Π線所作的剖視圖，圖 3是和焊接前的圖2 具有相同部分的剖視圖，圖4是說明其他實施形態的焊接 前的剖視圖。 該高爾夫球桿頭 1是中空金屬製的木頭型高爾夫球桿 頭，其具有擊打球用的面部2，從該面部2的上緣向後方 延長的冠部3，從該面部2的下緣向後方延長的底部4，插 入桿柄（省略圖示）後，並用黏劑等固定的桿插鞘部5等。 該高爾夫球桿頭 1由桿頭本體 1 0以及配重材剩：2 0構 成。桿頭本體1 0的底面部的後部上帶有開口 1 1 ;配重材 料2 0繫合在開口部，並通過焊接固定在桿頭本體1 0上。 元件符號2 1表示焊接配重材料2 0的焊接金屬（焊道）。配 重材料2 0僅通過焊接被安置在桿頭本體1 0上。 桿頭本體1 〇構成了除高爾夫球桿頭1上的配重材料2 0 以外的所有部分。在本實施形態中，雖然桿頭本體1 0是根 6 M255045 據熔模鑄造法鑄造成一體的，但是也可以其多個部份分別 通過鑄造、鍛造或衝壓成型等進行製造，利用焊接接合成 中空形狀。 開口 1 1位於桿頭本體1 0的左右寬度方向，即桿尖側· 跟方向的大致中央部，而且是靠近底部的最後部的位置上。 雖然在本實施形態中的開口 1 0大致是橢圓形，但也可 以大致是圓形、大致是方形或大致是多角形。當開口 11 是橢圓形時，最好長徑為桿頭本體10的左右寬度方向，橢 圓形開口的長徑最好是短徑的1 . 2〜2. 0倍。 在本創作中，整個開口 1 1可以設置在高爾夫球桿頭 1 的向下的表面上，如同該實施形態般，也可以開口 1 1的一 部分設置在高爾夫球桿頭1的向後的表面上。如此般使開 口延長直至配重材料的後面，並使其後面的一部分用配重 材料構成，能夠加大高爾夫球桿頭1的重心深度。 如圖3中所示般，使配重材料2 0同開口 1 1繫合，從外 側進行焊接，以便在開口 1 1的内緣同配重材料2 0的外緣 之間形成焊道。除T I G焊接和Μ I G焊接等電弧焊接以外， 電漿焊接最合適。再者，在本實施形態中，為了在容易進 行焊接的同時，還能夠提高配重材料2 0的焊接強度，如圖 3所示，在配重材料2 0的外緣同開口 1 1的内緣之間，設 置有坡口。 從能夠製造出尺寸精確的好產品的角度出發，配重材料 2 0最好利用炼模鎮造等鑄造法進行製造。為了使配重材料 2 0易於焊接，最好使其具有同周圍的底部同等程度的或在 7 M255045 其以上的厚度。配重材料2 0的厚度既可以整體均句分佈， 也可以是中央部厚、周圍邊緣部薄，大致呈凸透鏡形獻。 另外，本實施形態中的中空高爾夫球桿頭，其面部2的 壁厚要超過冠部3以及底部4的壁厚。如圖3所示，面部 2與底部4以及冠部3之間的連接部加大壁厚，以便保持 強度。 另外，並非特定在本創作之中，當把桿頭本體 1 0作成 不銹鋼製的球道木桿的時候，因為面部2需要有打擊球時 的強度，可以把厚度作成2〜3.5mm。厚度超過3·5πιιη以上 時，會出現質量過剩，結果不能夠再加大高爾夫球桿頭1。 同時，當厚度未達到2mm，會導致擊球時的強度不夠。 冠部3以及底部4的厚度是0.5〜2. 5mm，最好的厚度是 0. 7〜2. 2mm。當未達到0.5mm時，在進行重力禱造，特別 是利用熔模鑄造法進行精密鑄造時，由於金屬液流動性變 差，出現無法確保精度的問題。另一方面，當厚度超過 2 . 5 m m時，會導致質量過剩，結果無法加大高爾夫球桿頭 1。 底部4的厚度超過冠部3，能夠實現高爾夫球桿頭1的 低重心化。為達到此目的，可以加厚底部4的厚度，使其 一部分或全體的厚度達到3mm。 本創作的高爾夫球桿頭適用於球道木桿或是與其類似 的多功能桿。當使用球道木桿或多功能桿時，擊球面傾斜 角適合為13〜25°，體積適合程度為150〜220cc，質量適 合程度為 2 0 0〜2 5 0 g。這種情況下的配重材料質量，最好 是2 0〜5 0 g，特別是在2 5〜4 0 g的程度（高爾夫球桿頭1 M255045 質量的8〜2 5 %，特別是1 0〜2 Ο %的程度）。 接下來，就桿頭本體1 0的構成材料等進行說明。 構成該桿頭本體 1 0的金屬材料的比重最好是 6. 5〜 8 . 5，特別是6. 5〜8 . 0，6 . 5〜7. 0尤其好。通過使桿頭本 體的比重在8. 5以下，能夠實現桿頭本體的輕量化，例如， 設定桿頭本體的體積為150〜220cc，對於打高爾夫的人來 說，彳艮容易把球道木桿處理成便於使用的大小。 桿頭本體 1 0的構成材料最好是鋼，從具有優越的強度 以及耐腐蝕性的角度出發，特別是不銹鋼。作為不銹鋼的 馬田散體系、肥粒體系、沃斯田體系、析出硬化形等任何 一者都可以。桿頭本體1 〇是不銹鋼以外的鋼或非鐵系合金 也可以。下表1中是一例表示在本創作中能夠使用的鋼及 其它合金。 9 M255045 [表1 ] —--- ^"a I ----- --—. 組成例 不 錢 (SUS410) 0· 15C-12.5Cr 鋼(SUS405) 0. 08C-13Cr 錄鋼（SUS304) 18Cr-8Ni 銹鋼（SUS631) 17Cr-7Ni-1·1A1 赶星^鋼(S U S 6 3 0) 17Cr-4Ni-4Cu_0.15Nb 南張力鋼（ΗΤ8(Π 0.12C-0.8Mn-l.0Ni-0.5Cr-0. 4Mo 機械構造錳鋼 (0.4 〜0·6)0(0·7 〜2.0)Mn 鉻鋼（SCr430 ) 0.3C-0.7Mn-1.05Cr 非 舞·鉬鋼（SCM44iH_ 0.4C-0.7Mn-1.05Cr-0.25Mo 不 錄·絡鋼 (0· 25〜0. 55)0(1. 0〜5. 0)Ni-(0. 3〜2. 0)Cr 銹 表面滲碳硬化處理鋼 (0.09-0.25)C-(0.55-1.50)Cr 鋼 低溫用鋼 3Ni 低溫用鋼 9Ni 馬氏體時效鋼（250 ) 18Ni-8Co-5Mo ----. 高錳銦（哈德菲爾鋼） (0· 8〜1· 4)C_(l(M5)Mn 非 鐵 系 合 因科羅伊耐熱耐腐蝕鎳鉻鐵合 金800 46Fe-21Cr-32Ni-0· 4AH· 4Ti 另外，當桿頭本體是不銹鋼的情況，由於在焊接時不銹 鋼中的Cr同C發生繫合生成碳化鉻，有可能降低焊接的強 度。因此，當採用不銹鋼或其他的鉻鋼時，最好採用低碳 素鋼。 下面，就配重材料 2 0的構成材料進行說明。該配重材 料2 0的構成材料的比重最好是1 0〜1 3，特別是1 0〜1 2。 作為配重材料2 0具有高比重的同時，當桿頭本體1 〇是不 銹鋼的情況，從和不銹鋼具有良好焊接性的角度出發，最 適合採用鐵·鎢合金。 舉例說明在配重材料 2 0中作為鐵·鶴合金的合適組成 的質量百分比： F e 43〜54重量°/〇 10 M255045 w 25 -

[Prior art] In order to adjust the center of gravity height or depth of center of gravity of a hollow golf club head made of metal such as steel or titanium alloy, or the balance of the golf club head, a configuration made of a high specific gravity material such as tungsten may be arranged at the bottom Heavy material. When the head body is made of a metal having a low specific gravity, such as titanium alloy, and the weight material is made of tungsten or a tungsten alloy, it is extremely difficult to weld the head body and the weight material together. In Japanese Patent Laid-Open No. 10- 9 4 6 2 3, it is described that a cylindrical shape, a tape, and the like made of the same material as the base material of the head body are embedded or rolled around the mass body made of tungsten. Or wire-like material and weld it to the bottom. (Patent Document) Japanese Patent Laid-Open Publication No. 10-9 4 6 2 3 [New Content] (Problems to be Solved by the Creation) The above-mentioned Japanese Patent Laid-open Publication No. 10-9 4 6 2 3 On the outer periphery of the mass body, since the same material as that of the base body of the head body is welded after being welded or rolled, it is troublesome to install the mass body. In addition, water may be infiltrated between the interface between the mass body and the surrounding material which is embedded or rolled on the mass body, and the financial performance of the golf club head may be reduced. The purpose of this creation is to provide a Gore 4 M255045 golf club head to solve the existing problems mentioned above, so that the weight material installed on it is sturdy, has excellent durability, and is easy to manufacture. (Means for Solving the Problem) The golf club head of the present invention is a golf club head having a hollow club head body. At least a part of the downward surface portion of the club head body is made of metal. The golf club head partially fixed with a weight material is characterized in that the weight material is actually only installed by welding with respect to the golf club head body, and an opening or The concave portion recessed from the outside to the inside is connected with the above-mentioned weight material at the opening or the concave portion, and the outer edge portion of the weight material is welded to the inner edge portion of the opening or the concave portion. In addition, the so-called downward surface portion refers to the bottom surface, side portion, and other downward surface portions that are substantially opposite to the crown portion. This creation is about a golf club head. The counterweight material is actually only installed by welding with the head body. The installation of the counterweight material is both sturdy and has excellent durability, and it is also easy to make. In this creation, it is best to perform welding, and the formed bead is buried in the gap between the outer edge of the weight material and the inner edge of the opening or recess. The best welding is arc welding or plasma welding which can easily form a bead. The head body in this creation is preferably made entirely of metal, but may also be partially made of carbon fiber reinforced synthetic resin. 5。 When the golf club head is made of a fairway wood or a multifunctional golf club head, the specific gravity of the metal is preferably 6. 5 ~ 8. 5. Taking stainless steel with a specific gravity of 6. 5 7 as an example, a particularly suitable metal material 5 M255045 which satisfies the specific gravity is described. The specific gravity of the weight material is preferably from 10 to 13. By making the weight material a cast product, it is possible to easily manufacture a weight material with accurate dimensional accuracy. The counterweight material in this creation is best suited for crane alloys. In particular, when the head body is made of stainless steel, an iron-tungsten alloy that can be easily welded to stainless steel is preferable. Hereinafter, a suitable composition range will be described in detail. [Embodiment] Specific embodiments will be described below with reference to the drawings. FIG. 1 is a perspective view of a golf club head according to the embodiment as viewed from a bottom surface, FIG. 2 is a cross-sectional view taken along a line Π-Π in FIG. 1, and FIG. 3 is a cross-sectional view having the same portion as FIG. 2 before welding FIG. 4 is a cross-sectional view illustrating welding before another embodiment. The golf club head 1 is a hollow metal, wood-type golf club head having a face 2 for hitting a ball, a crown 3 extending rearward from an upper edge of the face 2, and a downward direction from the lower edge of the face 2. The rear extended bottom 4 is inserted into a shaft (not shown), and the shaft is inserted into a sheath 5 and the like fixed with an adhesive or the like. This golf club head 1 is composed of a head body 10 and a weight material remaining: 20. An opening 11 is provided on the rear portion of the bottom portion of the head body 10; a weight material 20 is fastened to the opening portion and fixed to the head body 10 by welding. The component symbol 21 indicates a welding metal (weld bead) to which the weight material 20 is welded. The weight material 20 is placed on the head body 10 only by welding. The head body 10 constitutes all parts except the weight material 20 on the golf club head 1. In this embodiment, although the head body 10 is root 6 M255045 is integrally cast according to the investment casting method, it can also be manufactured by casting, forging, or stamping, etc., by using welding. Hollow shape. The opening 11 is located in the left-right width direction of the head body 10, that is, approximately at the center of the tip and heel directions, and is near the bottom of the bottom. Although the opening 10 in this embodiment is substantially elliptical, it may be substantially circular, substantially square, or substantially polygonal. When the opening 11 is oval, the long diameter is preferably the left-right width direction of the head body 10, and the long diameter of the oval opening is preferably 1.2 to 2.0 times the short diameter. In the present creation, the entire opening 11 may be provided on the downward facing surface of the golf club head 1, and as in this embodiment, a part of the opening 11 may be provided on the rearward surface of the golf club head 1. Extending the opening to the back of the weight material in this way and making a part of the back surface with the weight material can increase the center of gravity of the golf club head 1. As shown in FIG. 3, the weight material 20 is engaged with the opening 11 and welding is performed from the outside to form a bead between the inner edge of the opening 11 and the outer edge of the weight material 20. In addition to arc welding such as T I G welding and M I G welding, plasma welding is most suitable. Furthermore, in this embodiment, in order to facilitate welding, and also to improve the welding strength of the weight material 20, as shown in FIG. 3, the outer edge of the weight material 20 is inside the opening 11 A bevel is provided between the edges. From the perspective of being able to produce good products with accurate dimensions, the weight material 20 is preferably manufactured by casting methods such as mold making and ball making. In order to make the weight material 20 easy to weld, it is better to have the same thickness as the surrounding bottom or more than 7 M255045. The thickness of the weight material 20 can be distributed uniformly as a whole, or it can be thick at the central portion and thin at the peripheral edges, and is generally convex lens shaped. In addition, in the hollow golf club head according to the present embodiment, the wall thickness of the face portion 2 is larger than that of the crown portion 3 and the bottom portion 4. As shown in Fig. 3, the connection between the face 2 and the bottom 4 and the crown 3 is thickened to maintain strength. In addition, it is not specific in this creation. When the head body 10 is made of a stainless steel fairway wood, since the face 2 needs the strength when hitting the ball, the thickness can be made 2 to 3.5 mm. When the thickness exceeds 3.5 mm or more, an excessive mass occurs, and as a result, the golf club head 1 cannot be enlarged any more. At the same time, when the thickness does not reach 2mm, it will cause insufficient strength when hitting the ball. 2mm。 The thickness of the crown 3 and the bottom 4 is 0.5 ~ 2. 5mm, the best thickness is 0. 7 ~ 2. 2mm. When the thickness is less than 0.5 mm, when gravity prayer is performed, especially when precision casting is performed by the investment casting method, the fluidity of the molten metal is deteriorated, which causes a problem that accuracy cannot be ensured. On the other hand, when the thickness exceeds 2.5 mm, an excessive mass is caused, and as a result, the golf club head 1 cannot be enlarged. The thickness of the sole 4 exceeds that of the crown 3, and the center of gravity of the golf club head 1 can be reduced. To achieve this, the thickness of the bottom portion 4 can be increased to a thickness of a part or the whole of 3 mm. This created golf club head is suitable for fairway woods or similar multifunctional clubs. When using fairway woods or multifunctional clubs, the angle of inclination of the striking surface is 13 to 25 °, the volume is 150 to 220cc, and the quality is 200 to 250 g. In this case, the mass of the weight material is preferably 20 to 50 g, especially in the range of 2 to 5 g (golf club head 1 M255045 8 to 25% of the mass, especially 1 0 ~ 2 0%). Next, constituent materials and the like of the head body 10 will be described. The specific gravity of the metal material constituting the head body 10 is preferably 6. 5 to 8.5, particularly 6. 5 to 8. 0, 6. 5 to 7. 0. By making the specific gravity of the head body below 8.5, the weight of the head body can be reduced. For example, the volume of the head body is set to 150 ~ 220cc. Handled to a convenient size. The material of the head body 10 is preferably steel. From the standpoint of superior strength and corrosion resistance, stainless steel is particularly preferred. As the stainless steel, any one of the Ma Tian powder system, the fertilizer grain system, the Vostian system, and the precipitation hardening system can be used. The head body 10 may be steel other than stainless steel or a non-ferrous alloy. Table 1 below shows an example of steel and other alloys that can be used in this creation. 9 M255045 [Table 1] —--- ^ " a I ----- ---.

Therefore, when stainless steel or other chromium steel is used, the most Low carbon steel is used. Next, the constituent materials of the weight material 20 will be described. The specific gravity of the constituent materials of the weight material 20 is preferably 10 to 1 3, especially 10 to 12. As a weight At the same time that the heavy material 20 has a high specific gravity, when the head body 10 is stainless steel, from the viewpoint of good weldability with stainless steel, iron / tungsten alloy is most suitable. For example, it is used in the weight material 20 as an example. Mass percentage of suitable composition of Fe · Crane alloy: F e 43 ~ 54 wt ° / 〇10 M255045 w 25--35 wt% Ni 1 3 ~ 1 9 wt% C u 1 3 wt% Fe • yan alloy of this composition Not only has excellent weldability to stainless steel5, but also good workability. The reasons for the limitation of the composition are explained below. 0% and below indicate the mass%. ○ In order to maintain good weldability with non-steel steel, The iron (F e) contained is 4 3 ° / 〇--5 4% 〇 When the iron content is not reached. When it reaches 43%, it cannot be charged Improve weldability. On the other hand, when the iron content exceeds 49%, the specific gravity of the weight material will decrease accordingly. The iron preferably contains 4 5 to 5 2 0 / 〇 :, especially 47 to-5 2 0 / 〇 Even better 〇 By adding W, the effect of increasing the specific gravity can be continuously and sufficiently maintained and the weldability can be improved as much as possible. Crane (W) is an element for increasing the specific gravity of the weight material. When W does not reach 25%, it will become "a specific gravity: a very low West 2 > heavy material. On the other hand, when W exceeds 35%, the weldability M of the weight material will deteriorate, so > the W content should be 2 5 to 35%, preferably 26 3 4%. S2 * Heavy material 6 ^ J Corrosion resistance, • To add 1: 3 ~ 19 9 ° / 〇 recorded (N i) 丨 Do not be: Tim force mouth 15 ~ 17% of nickel (N i) ° When Ni does not reach 13%, the weight of the weight material is not enough. On the other hand, when Ni exceeds 19%, the strength of the j weight material will decrease, and its specific gravity will also decrease accordingly. In order to increase the tactile property of the weight material, t is added by 1 ~; 3 ° / 〇 Copper (C υ) 〇 When the CU does not reach 1%, the corrosion resistance of the weight material will be insufficient. On the other hand, when Cu exceeds 3 ◦ / 〇, the weight material will become excessively soft. 11 M255045 The specific gravity of the weight material will become lower. In addition, the total content of Ni and Cu is preferably from 14 to 21%, especially from 15 to 20%. When the total content of Ni and Cu exceeds 21%, the strength of the weight material may decrease, and its specific gravity will also decrease. Although F e, W, Ni, and Cu are necessary components of the weight material, it does not matter that other elements are mixed without damaging the characteristics of the weight material. Other elements include metal elements such as Z η, A 1, M η, C r, Si, P b, Mo, Ti, and the C element as an example. When these elements together with the above alloys (F e, W, Ni, Cu) reach 100 ° / ◦, their content is preferably below 10%, especially 7%. In addition, when Cr is contained, because Cr is combined with C to form chromium carbide, thereby reducing weldability, it is preferable that the C content is 0.08% or less. In addition, carbon (C) can be stabilized by adding T i or N b which is easier to bind than C r, and it is possible to make it difficult to form chromium carbide. As shown in FIGS. 4 (a) and (b), a stepped stopper portion may be provided on the edge portion (inner edge portion of the head body 1 0 ′) of the opening 1 1 of the head body 10 ′. 12. When the welding is performed, the weight material 20 is locked on the stopper portion 12 and can be used for positioning. The stopper portion 12 may be provided on the entire periphery of the opening 11 or may be provided on a part thereof. The stopper portion 12 may be formed in a claw shape. In addition, FIG. 4 (b) is an enlarged view of a portion B in FIG. 4 (a). The stopper portion 1 2 may extend beyond the center of the opening 11 as shown in the figure. In the illustrated embodiment, the head body 10 and 10 'are all provided with openings 11. Alternatively, instead of the openings 11, a recessed portion recessed from the bottom side may be provided, and a weight material is fitted into the recessed portion to perform welding. 12 M255045 (Example) Hereinafter, Examples 1 to 15 and Comparative Examples 1 to 11 will be described. In Examples and Comparative Examples, SUS 6 3 0 stainless steel was used to produce the No. 3 wood head body 10 shown in FIG. 2 by an investment casting method. The opening 11 of the head body 10 is elliptical. An oval disc-shaped weight material having a mass of 30 g manufactured by the investment casting method was fitted into the opening 11 and TIG welding was performed to form a golf club head. The thickness of the center portion of the weight material 20 is 3 mm, and the thickness of the peripheral edge portion is 2 mm. The dimensions of the golf club head and other parts of the head body are as follows: 170cc in mass and 218g in weight (including weight material 30g) The inclination angle of the striking surface is 15 °. The wall thickness of the face is 2.7mm and the wall thickness is 2.0mm. The composition of the weight material is shown in Table 2 below. 13 M255045 [Table 2]

After welding, grind and remove the bead on the bottom side and observe the condition after welding. Fig. 5 is a bottom photograph of the golf club head before grinding in Example 1, and Fig. 6 is a photograph taken after grinding and longitudinally cut in the front-rear direction. In Examples 1 to 15, no welding failure occurred, and no welding defects such as cracks were found. At the same time, there is no obvious boundary between the counterweight material 20, the bead 21, and the head body 10. 14 M255045 When Comparative Examples 1 to 11 having the same longitudinal cross section as Example 1 were observed, differences in the respective components of the weight material portion, the bead portion, and the head body were observed. In addition, the precipitation of carbides in the bead portion and crystal grain boundaries around the bead portion can be clearly seen. In addition, it can be seen that the structure of the bead portion is inferior in uniformity as compared with Examples 1 to 11. In the golf driving range, the golf club heads 1 of each of the examples and comparative examples were further evaluated for actual driving, and it was confirmed whether cracks (cracks) occurred and whether rust was generated thereafter. However, there were no cracks (cracks). Moreover, even within one week after the actual evaluation, there was no rust. The golf club heads of the above Examples and Comparative Examples were placed in an environment at a temperature of 35 ° C and a humidity of 90 to 95% to perform a corrosion resistance test. Table 2 shows the observation results of the above welded portions and the results of the corrosion resistance test together. As shown in Table 2, the observation results and the corrosion resistance of any of the welded portions in Examples 1 to 15 were good. (Creation effect) As mentioned above, this creation can provide a golf club head whose weight material can be easily and securely installed, and also has good durability.
