A method of manufacturing golf club is to design the contour of a club head and a club shaft. Sheet metal forming for divided golf club head are formed by stretching the Titanium Alloy plate within the forming dies, then processed with stress relief. Assembly welding are processed in a vacuum chamber where inner-gas, argon, is filled therein to avoid any inpurity may occur on the product during manufacture. Temperatures for stress relief, solid solution and aging are controlled in various degree depending upon each different procedures in order to form a best quality in vacuum furnace where vacuum gauge is best under ten to the negative fourth power of TORR.
