摘要： PROBLEM TO BE SOLVED: To provide a golf club head, usually called an iron, having a super wide area expanded in a sweet area capable of enduring the use for a long period. SOLUTION: A clad material is made of a low specific gravity metal such as titanium, aluminum or these alloys having less than 5.0 of the specific gravity and a base material is made of a high specific gravity metal such as steel, stainless steel, copper, nickel cobalt or these alloys having 7.0 or more of the specific gravity. A clad member connecting the clad material with the base material is disposed on the face position of a head body 2 so that the clad material provides a ball driving surface and the base material of the clad material is connected fixedly to the head body 1.

摘要： PURPOSE:To prevent a pattern of a weld zone from being transferred to metallic foil by performing cladding by welding on both sides of a weld back bead, then, crushing a reinforcement part of weld, etc., and performing heat treatment in the electrodeposited face plate drum to manufacture a titanium plate. CONSTITUTION:Multilayer welding 2 of two or more layers is performed from the outside of the drum and claddings 4 by welding are performed on both sides of the back bead 7 of welding 2. Since Ti is active metal, gas shielded arc welding, etc., by inert gas, TIG welding, for instance, is performed. The parts of the reinforcement height 5 of weld from the outside and the cladding thickness 6 of cladding by welding are crushed by cold or warm plastic working and made to almost the same as the thickness of base metals 1. These are subjected to heat treatment at the temperature above the recrystallization temperature, weld metal of welding 2 and heat-affected zones 3 are made to recrystallization structure and weld zone hardness is conformed to hardness of the base metals 1. The drum where the pattern of solidified structure of the drum surface and the pattern of the difference in level by welding 2 are not transferred to the metallic foil is manufactured.

摘要： PURPOSE:To surely join the endmost parts of a titanium plate by subjecting the final ends of the titanium plate to continuous seam resistance welding in the method to perform lap joint welding of the titanium clad steel and the titanium plate by applying the titanium plate to the titanium cladding material side of the titanium clad steel. CONSTITUTION:In the method to perform lap joint welding of the titanium clad steel 1 and the titanium plate 2 by applying the titanium plate 2 to the titanium cladding material 5 side of the titanium clad steel 1 formed by joining titanium to steel base metal 4, the endmost prt of this titanium plate 2 is subjected to continuous seam resistance welding. In addition, in the method to perform lap joint welding, both endmost parts of this titanium plate 2 are subjected to continuous seam resistance welding at the same time. Consequently, the endmost parts of the titanium plate are joined surely and the steel base metal does not melt. Accordingly, a joined part excellent in corrosion resistance where a gap is not formed can be efficiently obtained.

摘要： PURPOSE:To easily form a colored film on Ti by anodic oxidation without requiring placing in an electrolytic cell by using the Ti as an anode, bringing a cathode into contact with the surface of the Ti while applying or feeding an electrolytic soln. to the surface, and supplying electric current. CONSTITUTION:Ti or Ti alloy is used as an anode and a portable cathode provided with a body impregnated with an electrolytic soln. is brought into contact with the surface of the Ti or Ti alloy while applying or feeding the electrolytic soln. to the surface. Electric current is then supplied to form a colored film on the surface of the Ti or Ti alloy by anodic oxidation. At this time, by using a mask or the like, a patterned colored film having a figure, letters, etc., can be formed. The hue of the colored film can be varied in accordance with the combination of voltage with current supply time. An aq. electrolyte soln. contg. about 0.5-10wt.% alkali salt of a strong acid may be used as the electrolytic soln.
