As the use of titanium in various industrial sectors has gained attention, interest in basic properties of titanium, alloy technology, processing technology and applications is increasing. Titanium has been developed for the purpose of aerospace and military use and has been called “the material of dreams”, but now its use is expanding in various fields such as implants, sports equipment, accessories, frames, automobiles, medical devices and heat exchangers. Titanium is abundant in the Earth's crust, but it is not found as the pure titanium metal state because of its strong binding force with oxygen. Therefore, in order to use it as a metal, it has to undergo a manufacturing process such as reduction treatment, so it belongs to relatively expensive materials such as 15 times of aluminum and 8 times of stainless steel per unit weight. Therefore, a research and development of processing methods of titanium and its alloys have been actively carried out, among which welding of titanium materials is a necessary technique for various application and flexible application of Titanium materials. In this paper, especially, laser welding method is discussed as a processing method which can improve the product quality and reduce the cost of the Titanium products. KCI Citation Count: 1
